Unknown user thank you for the video. I did notice that the car was a bit twitchy on and off the gas. I also noticed that down the straight your car appeared to loose boost. Were you able to fix that problem?

neye4rx7 09-25-13 08:40 PM

Kilito thanks for your reply and your inventation. I still have my apexi ecu just in case but I do have trust in your dads work. I will like to take you up on your inventation though maybe this will take away any doubts I have with this ecu. I have seen some of your dads car at the drag strip and yes they do work. Just wondering how he can tune it for quick boost coming out of corners on the lower rpm. Kilito I met you once before and you are a class act just like your dad. I am still working hard to get a few more parts for the fd and hope to see use guys soon.

RotaryEvolution 09-25-13 08:53 PM

i have a microtech in my car and i drive it everyday too, i have been for the past 8 years or so(back during the first group buy we got for them and the ONLY group buy we ever had on this site for them).

is it reliable? yes
does it work? yes
does it work well? sort of, but not by today's standard
can i switch things around easily with it? fuck no, microtech wants you to send it to australia just to do basic changes with it and charge out the ass for the changes
does it give basic functionality that other ECUs offer with their most basic ECUs? see last response and multiply it by 10. no times 10 is still no.

but i understand, your tuner specializes with microtech. it will work, it will work just fine. you already have the unit, you have a tuner who tunes the unit and that is all you need.

even their support has gone to shit when asking a basic question. i used to prefer them, i now push other products instead. they had their chance to build a whole new ECU, they chose to make the same BS garbage, giving you an idea of what they are about. the people saying to avoid the microtech just don't want you to be caught stuck in the rut we were sold into, unless your plans of modifying the car are very narrow then it might just work ok.

i can't even run more than 20psi without sending the shitbox back to australia and paying some absurd amount like $350 to do so. that's 1/3 of a brand spanking new REAL ECU.

even the megasquirt is more advanced now than the highest line MT units, made by kids who tinkered in their garage with transistors and resistors as a hobby to start with AFTER these microtech units were sold for many years already.

Drag vs roadcourse
 
Well I have seen them work well on drag cars but I am not too sure on how well they work on rx7 used on road courses. On road courses you are on and off the throttle. I also dont know how well they work on street cars as far as driveabilty. I run a power fc and its ok.

RotaryEvolution 07-10-16 12:25 AM

3 year bump?

funny how the answers are still the same though. microtech is that slow with updates.

my microtech still works and it works fine, but it's still a bit of a turd.

Rotaryevolution what type of driving do you do with your rotary and do you have any on and off power jerking? Having a hard time getting.peoples experience on this ecu. I bought a lt10. I know its not the latest model in ecu but pretty simple and I see a lot of guys runnung them in Australia and on the drag seen.

RotaryEvolution 07-10-16 11:27 AM

i've run it for about 10 years and about 60k miles, mostly daily driving, normal driving with the occassional foot to the floor 100-120mph to pass a car or 5. one time up to 145mph or so.

never really tracked the car, ran it at the drag strip a couple times.

gets 23.5mpg highway, never bothered to calculate city mpg.

it's never treated me badly or left me by the side of the road, IMO it's the easiest ECU to tune aside from these newfangled ones with autotune functions, if they actually got them working properly yet. the tune has been untouched for i don't know how long(maybe 5 or 6 years?), and i don't keep a wideband in the car to monitor the tune, because honestly it has never given me a reason to need to monitor it.

if tuned properly the microtech works fine, but you're locked into the boost level that your ECU map sensor is configured to.

Rotaryevolution thanks for the good info. Pass 5 cars.lol That 23 mile per gallon hwy is not bad in my book. All those 60k miles on one engine with microtech? How much boost and rwhp? Also cant the.boost be controlled by adding a boost controller?

yes, just the one engine, about 325whp, i didn't beat the snot out of it every chance i got but i took it on a few 1k mile road trips.

you can't raise the boost beyond what the map sensor can read, on my lt8 it was originally sold with a 2.5bar sensor, if i want to run more boost than the sensor can read then they want me to send the unit back to australia...

I know the wall of text on the MicroTech seems impressive, but it can't do half of the things the Motec can. Hell, a Megasquirt can do more than a Microtech if set up properly.

Wow. A lot of info there acr. Can you give to me in a nut shell. A ecu for dummies if you will. Lol. How will the motec out perform the microtech far as driveavility/power delivery/engine temps/does it reduce turbo lag/make more power or torque. Not really interested in traction control or lunch control.

I'll try and go down your list as best as possible.

The power that an engine delivers is 100% dependent on the quality of tune. If you plug in the exact same numbers (or equivalent values in the ECU fields) both controllers should and will make the exact same power. This is provided you scale the maps identically and such.

As far as driveability, the Motec will shine as long as it was tuned correctly. The interpolation of the map cells is much finer than the MicroTech. You can have better transient response in the small areas of the map that the MicroTech just doesn't have the resolution for.

Will this be noticed in every application? Maybe. Depends on the tune, supporting mods, the tuner, and other factors.

As far as power delivery, temps, and more power or torque, again that is dependent on the tune. If you tune an engine incorrectly, it can be reflected in the coolant and exhaust temps.

As far as turbo lag, sure. If you have anti-lag turned on, but you don't want to do that on the street. Turbo lag is dependent on the type of turbo and the port shape, airflow volume, etc. You can not change it with a tune, unless you are using some kind of anti-lag strategy or significantly change up the tune. Again, as an apples to apples comparison we assume all fields have identical values inputted.

The Motec has closed loop boost control, which can affect spool times compared to a manual boost controller. That involves two different control strategies and is not equivalent in our comparison.



Again, there really is no comparison. Try comparing a Windows 95 PC and a current and stable running Windows 10 machine as far as performance. Sure, you can browse the web and do your email, but the MicroTech doesn't get the updates.

I would not waste my money on either of these controllers. The MicroTech is an outdated controller that doesn't have close to the inputs and outputs a Haltech, AEM Infinity, Adaptronic, Link/ViPec, or a Megasquirt Pro has.

The Motec is primarily designed for racing applications (as are all aftermarket controllers), but you have to pay for additional features. Many of the controllers I listed above come with them unlocked.


Lets simply look at price:

Motec M800- $3000

MicroTech LT16c- $1200

Haltech PS1000- $1400

Adaptronic E440- $1300

MS3X- $800

MS3Pro- $1200

Link Fury- $1800


If you shop on price alone, the MS3X is your best choice. Find a reputable tuner you trust. See what they support. You will be worlds ahead. If they only support MicroTech, that's fine. Just understand that you can get so much more with a different controller.






I will quote what RotaryEvolution said three years ago about the microtech.

i have a microtech in my car and i drive it everyday too, i have been for the past 8 years or so(back during the first group buy we got for them and the ONLY group buy we ever had on this site for them).

I would recommend you do some research on your own and come to your own conclusions. You seem hell bent on going with a MicroTech because you keep asking about it, even when you have been told it pales in comparison to modern engine controllers. MicroTechs had their place. They do "work", but wouldn't you want something so much better?

spintriangles 07-11-16 06:01 PM

microtech
 
Appears you are right. Microtech is the way I am leaning based on my tuners words. Just want.to make sure I am not making a big mistake. I would even be willing to change tuners just to switch ecu. I have read this thread and many others but as far as track day use and dd the info.seems limited. I was hoping someone would.chime in who.runs.there car on the track and dds it would.chime in. All thus info is valuable and I will continue to research it. My cars engine just got rebuilt with street port,aspec turbo kit 6262 1ar and re v mount. Just want it to run well.

ACR_RX-7 07-11-16 06:11 PM

Your tuner probably likes them because they are easy to tune and are well known on a rotary, but that does not mean it is the end all be all. As far as a PCM suitable for a daily, they really all can be used that way. The microtech is not some idle/wide out PCM that only does two things. It can be driven. Any PCM can be used for everyday driving. It just comes down to the features and capabilities you want.

Hell, the PowerFC is a fantastic unit....for it's time. Loads of people have used them and continue to do so, but wouldn't you rather have something a bit more up to date?

Think about it this way. If any aftermarket controller could not be tuned to run on the street, do you think that people would go out and purchase one at all? We have multiple subforums dedicated to multiple types of controllers. Many people have their favorites for one reason or another.

If you actually read through this thread, you would see the same messages over and over. It's a decent PCM, but has major shortcomings. The same thing is repeated over and over. Yes, it works, but it's old and antiquated.

Go onto the various subforums and look at what people run and what they like. For my money, go with a Haltech Elite 1500 or an MS3 Pro. The Adaptronic is the new kid on the block and is also very popular. You really cant go wrong with many of the options out there, but if you are going to drop the cash on a controller, get the best one for your dollar. And, in your case, get one your tuner supports. Otherwise, you may need to find another tuner.

I'm not a tuner and can't comment about the Microtech. But the largest FD user knowledge-base, especially here on the forum, will likely be the PFC.

Back in the day, the Microtech LT(s) series was delivered full of promises. Fast CPU, continuous software updates from Microtech, and additional features continually being developed. How many updates have we received since the thing was released 10 years ago? Zippo. So all of us LT8s (and this translates to the higher numbered ECUs as well) are stuck with an ECU that offers:

-poor interpolation between load points
-ridiculous timing model based on a distributor paradigm
-no closed loop O2 control
-extremely limited I/O
-crappy datalogging
-software from the late '90s

I'd highly recommend you go to an ECU that was designed in this century such as the Haltech Platinum series, MegaSquirt 3 (if you like DIY), or similar.

And by excessively rich, I mean that it's difficult to lean out the light load bins because of the poor resolution and interpolation. Lean those bins out and there is a big hump when the engine moves into the next bin. Terrible.

Not running an O2 sensor?!? Why in the great name of all that may or may not be holy would you do such a thing?! Widebands are a great tuning aid and necessary for good datalogs. And any ECU that doesn't suck (so not Microtech) can use an O2 sensor to continually adjust the mixture to keep the engine at optimal AFRs for both power and economy. The better ECUs can even self tune the AFRs via the O2 sensor.



You won't run into any problems mechanically running a Microtech. It is a reliable ECU that will do the job. However your tune will never be as good as the more modern ECUs. And considering Microtech has not dropped their price, there is zero advantage to buying one over a decent ECU.



I have over 10 years tuning Microtechs on everything from a 146HP stock port NA to 500HP bridgeported big turbo cars.

For example, modern ECUs allow FULL closed loop AFR control over the entire load table to tightly maintain an appropriate AFR regardless of conditions. They also support autotune which makes it a hell of a lot easier for a single person to tune a car. Additionally things like engine protection if the AFR starts to drift.

A Microtech isn't cable of any of this. The most important of the above features are closed loop.



I thought I was clear: Because the Microtech offers poor resolution and interpolation, the car at light loads must be tuned richer than it should be to maintain smooth operation. So you're wasting fuel, stinking up the air, dropping efficiency. Also the on/off decel on the Microtech doesn't have any smoothing. Zero idle control so the idle must be higher and richer than a proper ECU allows.

Oh and the timing control on a Microtech sucks. There's no other way to describe it. A virtual distributor...yeah, take something as limiting as a dizzy and then simulate it in software. Bloody brilliant (sarcasm).



Buy a Haltech P1000 with a plug and play FD harness then. Done and done. A well known supported configuration with a great ECU, large amount of forum support and a solid track record.

In this day an age, the ECU does far more than just control fuel and spark.



You are absolutely correct.



The Microtech is a fine ECU if you intend to use it on the track only. It is only on the street where its deficiencies quickly show.

I remind you I've been tuning Microtechs (as well as many other ECUs....Haltech, MegaSquirt, Wolf) for over 10 years.


Originally Posted by RotaryEvolution (Post 11455631)

microtech
 
Still no one has really chimed in as far as track days. Sure wish I could see a vid of a car on the track running microtech. So far it sounds like I will have to use the microtech. I dont want to adjust any setting once the car is tuned so I dont understand why I would need a hand held tuner.

ACR_RX-7 07-11-16 07:00 PM

You don't need a handheld tuner. Many people have a PFC Commander so that they can datalog. The MicroTech does not datalog well. Not many people are going to come in and chime in on track days because you posted in the New Member section. If you want to know more, go to the MicroTech subforum.

Why are you concerned about adjusting the tune? Once a controller is tuned, it's done. You don't need to go back in and mess with it unless something has changed.

Also, you will not find many videos of people doing a track day with a MicroTech because the MicroTech was popular before YouTube and cell phone videos that could display more than ten pixels.

I know Aaron Cake uses a MicroTech in his FC, so I'll link a couple of his vids.




Again, I am not sure why you are hung up on the track days part of it. if the controller can run the engine on the street, it can do so on the track. In your first post, you mentioned you had a PowerFC. Why not stick with that? It's outdated, sure, but quite a bit better than a Microtech.

Howard Coleman ran a PFC on his 500+hp FD for years and eventually switched to a Vipec V88 for additional datalogging support.

Good video. That car seems to run well. It does not look choppy. Looks like a smooth acceleration. I live in Orlando

Aaron Cake 08-01-16 10:45 AM

I am of course the owner of the car that is in the videos above.

The car is a fair weather daily driver, running a Microtech LT8s. However, I would like to make it very clear that this car is about as removed from stock as one could get. It's a 6 port high compression turbo engine (S4 NA block) with a mild bridgeport. GT4088R turbo, and my own custom designed and fabricated intake manifold with runner lengths, diameters and plenum volume calculated to the engine (as best as I could guess/estimate when I built it).

I chose the Microtech because at the time, in the early 2000s, ECU choices were rather limited. The Haltechs at the time had known VR sensor issues with the FC CAS and were susceptible to noise (one loves to see 16K RPM spikes in their datalog while figuring out why the apex seals are now located in the muffler). The besides the Haltech, there was only the Wolf series (which could not run stock trailing coils), the Tec ECUs (expensive, lack of true rotary support), Motec (write a blank cheque). Megasquirt was at the 2.2 board level. Microtech introduced the LT8s advertising a new 32 bit processor, said that they would offer continuous software updates for the ECU and tuning software. And now more than a decade later, how many software updates have their been? Zero.

The ECU has been acceptable to me. It is a very reliable ECU. Easy to tune to a point. But once you reach that point you are stuck. There really is no way to refine a tune. The poor interpolation (seriously, vacuum bins ever 5"?!?!) means that you'll never have both a smooth tune and an economical tune. With a refined Microtech map that I have a considerable amount of time into, my car starts up first try, idles cold, and runs fine. But I continually bump into the limitations of the Microtech. I can't run an idle valve. I can't control multiple fans (oh, and the fan control is idiotic...set an on point for the fan which is only adjustable in 2 degree steps, but the off point is hard coded at 5 degrees below that). I don't have extra inputs to monitor sensors. The data logging is terrible. No closed loop so there is lean section in my map for cruise that the engine occasionally hits at light throttle acceleration. And the timing, oh the timing. It's a complete compromise. Without a 3D table I can't bring in nearly as much timing as I want at decal because the correction curve is very limiting. I also can't increase the timing in the cruise area because one can't be too aggressive with the base RPM curve as the stupid correction curve needed (think mechanical and vacuum advance, virtualised) can't compensate properly as the engine goes into boost in those areas.

Fundamentally, the Microtech works. If your tuner is familiar with it, then that ECU might be the best choice.

Though at that point I would recommend a better tuner.

There are MUCH better choices these days for equivalent or less money as already laid out in this thread.

For a track only car, if that's the question, then the Microtech works fine. A lot of the refinement we need on the street isn't needed on the track. But where it starts to fall apart as a track only ECU is the fact it datalogs about as effectively as a passenger writing down numbers on a clipboard during the run. So if you don't care about datalogging, but want a solid, reliable and easy to understand ECU, then the Microtech is fine for your track car.

I'd also like to point out that looking at some AutoX videos and then saying "that car runs fine because it's not choppy" is in no way a way to evaluate an ECU. No ECU should run "choppy" on a track scenario. The track is about quick throttle transitions and big changes, exactly where basically any ECU will do the job.

Thanks for providing input, Aaron. I kept trying to say the same things over and over again and felt like I was talking to a wall.

I still stand by what I said before. A person can get so many more features for about the same price, especially the improved datalogging. In any racing situation, datalogging is key to maintain and edge and make sure the car is running well. The poor interpolation and map resolution also seems to me like a huge limitation in any situation, especially with the newer controllers on the market.

Aaron Cake 08-06-16 10:37 AM

Yes, that's absolutely what it boils down to. There's almost no point in buying a Microtech these days when there are multiple better options for the same or less money. And all of them have software on the computer side that doesn't make you want to punch babies when you use it!

Oh, that's another thing I haven't mentioned: the stupid Microtech laptop adapter. To access the Microtech via computer you must pony up another $100 to buy a hardware dongle containing a microcontroller that translates the signal from the serial port to the equivalent of the hand controller so the Microtech can understand it. As I recall, this was done by Microtech to avoid paying licensing fees to someone else who had a patent on direct serial communication with an EMS. Oh and that dongle is where you can save your maps, up to 4 of them, if you wish.

ACR_RX-7 08-06-16 10:56 AM

Isn't it true that you can only save the maps to the dongle and not to a disk? Basically, you are unable to send another person a base map.

spintriangles 08-06-16 12:21 PM

Aaron thank you for your input. You seem to know a lot about Tunning. I wish I was that brave to tune a rotary car. Adaptationics seems to be a good ecu but my Mechanic tunes microtech. Just making sure I was not going to start hating my car if I switched to microtech

Find a better tuner. Get a controller that is modern and has better support. The microtech will work, but it is grossly outdated at this point.

Also, tuning any and all ECUs are just about the same. They all have fuel maps and timing tables. They all squirt fuel into an engine and fire a spark plug. If your tuner will not touch anything outside of a microtech, it might be time to find someone who is comfortable with more ECUs and even more car lines.

If you want to see for yourself, you can download the Haltech software and the Megasquirt software for free and play with it. You can see how the tables are arranged and how to adjust them. They are all basically the same, for the most part. I also just downloaded Eugene for Adaptronic and loaded a basemap just to play with. You can get in and play around without having the ECU hooked up.

About 8 years ago, I built a car for a customer. It was a twin turbo 3000GT with an AEM standalone in it. I dropped it off at a tuner nearby to get it dialed in. The guys there specialized in Camaro and Mustang drag cars. They were happy to tune the 3kGT and said it would take a little longer than usual just so they could familiarize themselves with the software. The car ended up making 550WHP when it was done. It really is all about the tuner, less so the controller. If you have a tuner that prefers the Microtech that's fine, just be aware that at your price point, you can get so much more.

spintriangles 08-06-16 12:57 PM

For what I gather in this thread microtech is the carburetor of ecu. It will work on all applications just like a carb but not as efficient

And control ignition like a distributor.

Your assessment sums it up.

spintriangles 08-06-16 01:06 PM

I am not much into fancy things like launch Control and changing around maps. I like adoptronics for it seems more spot on as far as fuel delevery, spark and timing which= better running car but i would have to research a good turner in this area. I can't afford for some half ass turner to blow my engine trying to tune it.

Like I said, all ECUs do the same thing. It just depends on how precise and sophisticated the controller itself is. Almost any controller these days has launch control or what you call "fancy things".

If your current tuner only does Microtech, chances are he is not very experienced overall. It's just how it sounds. I'm not saying to find the guy who tunes everything and anything, but keep in mind that any good tuner will stay safe and not push the engine for some ungodly number. A well running and balanced car once done keeps a guy in business. If they are known for popping engines, they will also be unemployed fairly quickly.

I'm going to guess that you have a Facebook account. Look up "Tuning Fork" on there. He's the guy who guest appears in Mighty Car Mods. He has several videos about these topics, from choosing a controller, to getting your car ready, and finding a tuner. It's all generic really, but you need to make sure that before you strap down to the rollers that your car is ready to go.

Any good tuner will have a checklist or at least will inspect and chat with you before any work is done about the process and what needs to be done. Far too often you hear about guys who pay a couple hundred bucks, get on the rollers, they make a power run and KABOOM. Some tuners try to advertise that they can get more power out of a car than anyone else. This is usually a sign that they are only interested in the number on the sheet, not the welfare of your engine.

There is a guy here in Washington who claimed to get more power out of EVOs and STIs than even English Racing. He also claimed that his tunes would do better on a car even after English had just gotten done with a tune. All of those cars he tuned are now getting new engines. All. Of. Them.

To be fair, he did get more power out of them.....for a little while.

spintriangles 08-06-16 01:46 PM

Ya. I have a lot of those big Number tuners in my area (central,Fl). The other problem is not many of them tune rotaries. My guy has a very good rep with rotaries and tuning them but only tunes microtech. He believes they were built just for rotaries. I wish he tuned adoptronics

Sort of true, sort of not. The most recent version of the Microtech laptop software allows saving and loading of maps. At least, it is in the menu. Oddly the Save is in the File menu, and the Load is in the maps menu. I think that speaks volumes for how user friendly the software is. Now I say this is theoretical as I have not tried the feature myself nor heard of anyone else using it. And I think the feature saves only the fuel map, not anything else. Knowing Microtech it will also be locked to that particular ECU so no sharing. Additionally, the feature doesn't work offline. One must be connected to an ECU (why I've never tried it). So no opening up a map to review or work on without being connected to the car and overwriting what's in the ECU!

Typical Microtech. When they do implement a feature, it's only 85% of the way and years too late.

I've tuned almost all of the popular ECUs out there (with exceptions of the Adaptronic and Motec). To be honest, the Microtech is actually the LEAST user friendly to tune. Sure, it is the simplest ECU as the tuner simply doesn't have the options other ECUs present, but the software is just so, so awful. It's like being thrust back into DOS Shell when you've been using Windows 7. Arcane key combinations, mimicking the hand controller, no way to highlight and scale maps. It's basically a terminal emulation to the ECU.

I completely agree with the statement that if the tuner only tunes Microtech and is unwilling to even look at something else (probably because his understanding is barely above carburetor, and he likely also says stuff like "I don't do wiring!" or doesn't understand how a relay works) then find another tuner! Frankly anyone who has tuned a Microtech should be able to get used to another ECUs tuning software fairly quickly. Their eyes will go wide with how much it doesn't suck. There virtually is no difference in the basics of tuning no matter what ECU.

I'd also say I agree with the suggestion that you download the Haltech and Megasquirt software (TunerStudio) and take a look. I have Megasquirt maps on my website. Load one up in the software and poke around. You can find Haltech maps on this forum to do the same thing.

To be competitive in the market, and not saddle customers with limited functionality for the same or more cost of other products which do much more.

Kilito Racing 08-08-16 09:55 AM

It works better than most. I've had my car running 3+ years with it, no issues.

ACR_RX-7 08-08-16 10:15 AM

Once running, they work just fine with no issues. This is a guy who wanted to install a Microtech and was asking about it's functionality.

Sure, 3+ years ago, no one would steer you away, but today there are far too many other options that are more equipped and easier to tune AND more precise for the same or lower price.

I look at it from several angles, but it's been summed up adnauseum by other members.
Pros: They work.
Reliable.
Noise free

Cons: You have to send it back to Aus for any work and upgrades
No software updates at all the last 10 years
Tuning software from the DOS era
Poor interpolation
Poor datalogging
Fewer inputs and outputs than other controllers in same price range
Lack of additional features (closed loop, traction control, etc)

No one is denying that the Microtech will work just fine and last a long long time. Probably one of the most reliable out there, but controllers today are built better, have more features, better user interface, better datalogging, superior cell resolution, and more.

It comes down to the cost to benefit ratio. The cost is on par with a Haltech Platinum, or a Adaptronic 440, but has a fraction of the features and support.

If I go to Best Buy for a new laptop, I'm going to expect Windows 10 on a Quad Core Intel, not Windows NT on a Pentium 2 unit.

Kilito Racing 08-10-16 01:06 PM

The new microtech have a lot more features than you think including traction control, boost control, data logging, ect.. My microtech does not have those features. Even so, my old out dated one runs better than most of the current competition.

ACR_RX-7 08-10-16 01:35 PM

The onboard logging on the LT10c, which is the new unit, is an add-on upgrade and only stores 5 minutes of data. Otherwise, you must log directly to a laptop. A bit inconvenient in my opinion.

For the price, there are better options. I would like to know what you mean by


Even so, my old out dated one runs better than most of the current competition


The runnability is dictated by the accuracy of the tune and the setup. If two controllers have the same map resolution, in the Microtechs case 16x16, and they both have equivalent values inputted, the engines should run exactly the same.

The interpolation of many newer controllers is better between cells, and I know that Haltechs have larger maps with better resolution. They should, in theory, run smoother with better transient response, all things being equal.



Spintriangles, who has been asking about these controllers said in his early posts that he had a PowerFC and just bought a LT10. He did not say which LT10, but his concern was mainly with daily driving, track use, and if he was going to be happy with it in the long term.

The answer is very likely yes, but when there are other newer options available, it's a good idea to consider a controller that a person can grow with and end up with more precise control.

Kilito Racing 08-10-16 01:49 PM

What I'm saying by that is that my car with old technology still runs strong on the track and street at about 4-500+whp depending what I'm doing.

Except when we look at those features, they are enabled in a typically Microtech restricted way. Data logging to the ECU is a $100 option. And then you find out that it's limited to a silly low number of events. And the same old same old user hostile tuning software makes you want to punch babies when you switch from something awesome like TunerSudio back to Microtech. And where's the closed loop with AFR tables? Boost control is still just a "black box" algorithm that if it doesn't work, it doesn't work. Can't set boost per gear, per RPM, boost limits via wastegate, etc. There is so much backwards with the Microtech it's not even viable in today's ECU options. Oh, that datalogging. Most ECUs now just take an SD or MicroSD card so they can log to the capacity of the card.

Never would I say that the Microtech doesn't work. It does work, and works very well for its limited feature set. It's reliable, and can be tuned well enough to make a car drivable by 1980s standards. But here's the thing. Why pay the same price for an ECU with 20% of the features when equivalent money buys you a modern unit? What's the advantage?

A 386 SX/16 runs Microsoft Word 3.0 just fine on Windows 3.1. A Core i7 6700T runs Word 2016 on Windows 7 (Windows 10 is annoying) just fine. Which one would you pay $1000 for? Would you even look at that 386 SX/16 if it was available today? So why look at Microtech?

And to be a little nasty: A $220 Megasquirt 1 w/3.0 board (granted, you are soldering it up yourself!) runs a rotary better than the latest $1200 Microtech could ever dream of. And that's on a 12 x 12 fuel table vs. the Microtech 16 x 16!

My car, a 500HP bridgeported FC, is a dailyish driver running a LT8s. It works fine. But years ago I bumped into the limitations of the Microtech. I want to control 2 cooling fans. I want closed loop AFR control. I want an idle valve to high idle the car when cold and compensate for electrical loads. I want logging of fuel pressure, oil pressure, oil temp. I want engine protection features based on fuel pressure, AFRs tied into datalogging so a log starts anytime there is something odd as well as lighting a CEL. I want smooth interpolation. I want idle maps because idling the bridgeport on the main fuel table is a compromise. I want flex fuel capability. I want tuning software that doesn't suck donkey ass, that actually allows me to save maps! I want extensive datalogging review capabilities and the ability to auto tune the map based on real time AFR output AND offline datalog analysis. A $660 Megasquirt 3 (assembled!) provides all this and more. Well, to be fair, that MS1 provides a good subset of these abilities as well. Or for the same price as the current LT series, I could buy an MS3-Pro.

spintriangles 08-13-16 01:16 PM

Don't need
 
I don't need no stinking traction control. The Control is in my right foot. At of all the things listed looks like the only things I would miss is being able to boost different psi in different gears. Man that is kinda of cool. Also controlling fans sounds good. I have temp gauges and so on to monitor engine temps so that I not worried about. Just want to make sure I have a reliable system with a reliable tuner that will allow my car to work properly (haul ass). My tuner is my Mechanic and he is very well respected in the rotary community. Kilitto I saw your video. At what Rom are you getting full boost,what was the full boost and what turbo?

spintriangles 08-13-16 01:24 PM

For me
 
Microtech is the choice due to my Mechanic being able to work on my car and tune it. It is really that simple for me. For what I gathered they are much better ecu but I am not a tuner not Mechanic. I am limited to what my Mechanic can do and he does microtech. He makes them work well on many cars in central fl. Many cars pulling good reliableable power coming out his shop. If he was ever to go adoptronics I would switch to that in a blink of an eye though.

ACR_RX-7 08-13-16 10:42 PM

Your car, your call. We at least tried to help inform you of the choices out there.

You say that your tuner/mechanic is well respected and regarded and that you trust him. That's fine, but I still stand by what I say. If he is not willing to work on any other controller, then I personally think you should look elsewhere.

I know you don't think you need that many features, and that's also fine. Traction control is not the features that are important. You seem to be hung up on that one specific feature.

The larger benefits that Aaron pointed out are superior fuel control, more inputs, idle control, datalogging, and the ability to save and submit maps for review. Load of users on the forum will have a car running, post their logs and a map file, and other users will pick it apart and try and help. You can't do that with a Microtech.

Again, I never said that the Microtech will not work. It works just fine. If you are ok with settling for "just fine". My car will get a newer controller with more inputs and outputs with more features because that is what I want my car to have.

I would at least take Aaron's advice. He has been around for a long time, helped many users, and has a Microtech on his own car. He knows the system very intimately and has laid out in detail what he has encountered.

Just understand from my perspective that you came to ask a question about it, we gave you our input, and in the end stuck your fingers in your ears and said you don't want a better controller for the same cost with more features. Because your tuner said so.


Edit: Also, you said you had a PowerFC in your original post. Did you already pull it out? Why not stick with it? The PowerFC is a better controller than a Microtech in certain respects. Especially since it can run factory twins, if you still have them.

spintriangles 08-14-16 07:40 AM

Not really
 
The views and facts on this subject have not gone on a def ear. I hear everyone loud and clear. Instead I am very grateful for the info that Aaron and others have game me. The one of the reasons I joined this forum is to get educated and more familiar of the working of my rx7. I have had this rx7 since 98 and have had many horror stories due to poor mechanics,techs and tuners. With this said I finally I have a well respected machanic,tech and tuner. Please don't think that I don't appreciate those members who are trying to help. Like I said before if I had someone I trusted like my Mechanic to do adoptronics it would be a no brainer. Considering I don't I have to go what I believe will be the best option for me at this time. When you have been screwed as much as I have you tend to compromise just a little. By the way this is at no fault of my car it is a great machine but in this area we have a lot of rotary con artist. Many around here say they know but don't know ish blow your motor and you get to eat a rebuild. Maybe ok for a young man with no real responsibilities but a no go for a grown family man with a passion for family and rx7s.

spintriangles 08-14-16 07:50 AM

To add to my last post. Based on the info gathered I too believe the adoptronics is a more up to date option. I do not knock the ecu nor its tuners. Like I said before carburators vs fuel injection I get it. My decision is not a disrespect to those who chimed in. Just my choice based on my particular situation at this particular time.

I get full boost around 3500-4k. Full boost in the car is 20 psi. Turbo size is a 67/65 precision. My car does have an idle valve. When the car is cold or when I turn the a/c on, it will raise the rpm to compensate. I've never had the need to have my map reviewed... But I guess that would be cool if I needed it.

spintriangles 08-14-16 10:51 AM

Not bad at all
 
I also have a pte but it is a 6262 bb 1ar. Hope to get full boost near that same Rpm.
