What is better option PFC or Microtech
 

I have to decide for my single project.
I was gona get PFC like everyoneelse but THE PFC now on back order.
and my local tuner strongly recommands Microtech.
I like the Idea of datalogic also I can keep the OMP if go with PFC.
but I have to pay for datalogic box.
Microtech I have to give uo the OMP but it comes with new harness so OLD harness can go! also I can buy handset for 200 and some what outperformes the PFC..

What is better choice?

Who is going to tune the car?

if your tuner likes microtech, then I would go with that, he probably has more experience with it/ likes it better.

I've had both. I really like the Microtech better. But as stated you should go with what your tuner is most familiar with.

BINGO!

Microtech has slightly less resolution, but doesn't matter all that much. I feel more tuners are familiar with the PFC.

Oh whada you know.... you don't even own a FD!!

Power FC

Microwreck = gheto ;)

Do yourself a favor and look into the new Haltech E11.....VERY nice ecu....

Do yourself an even bigger favour and use a real ECU like an Autronic SM2 or SM4.

Seriously ownes all the other pretenders on the market, pm enzo250 or frode of this forum and get with a decent product v's the plethora of garbage thats hyped up to be decent when its far from it by comparison to real top shelf units.

Autronic is the top shelf but with a middle shelf price :) :) :)

Do yourself the BIGGEST favor and check out the other cars your choice for a tuner have done and in that way you can make a decision based on the actual results.

Good Luck.

and there in lies the BIGGEST FALICY in this *game* that you base a decission base on a persons limitations and or bias rather than that of a technicaly superior product (on paper and in reality) !

anyone competent with basic level of ability can tune an Autronic or a motec, if your tuner/god of choice recommends against it and suggest another based on their lack of skills or knowledge then they are pretty useless in my books ;)

seperate the hype and garbage from reality and find competent people to do your work and you will be fine ;) thats the biggest and best advise you can have :) :) :)

I dont think Crispeed said to go to a tuner because of their limitations, he meant go with a tuner based on their results, regardless of management. Like you said, if a tuner is good, he can extract power regardless of management.

I run a Electromotive TEC3R, have had excellent results with it. Now is it technically inferior to other products as well because my tuner suggested it? I don't think so. However he also did NOT say, oh dont go with so and so management because it sucks, he based his recommendation off of past hard real world experience and results, not hype or bias as you put it.

I would stick with what is proven to work within your price/budget, as we all know not everyone has the funds to buy a top of the line motec.

hear hear, lol. Seriously, I've seen great results with the haltech and microtech. IN the 1/4 mile I think microtech has proven itself time and time again. I'm using the lt10 and don't expect any issues from it. It's a fine ecu that again has been proven.

I'm been semi-looking at getting a new EMS. I'm currently using the E6k, It runs the car great, its just old and doesn't have the features that i want to play with.

I really want to play with the new Electromotive TecGT, I know a local guy that is running one in his Subby, i'm going to check it out sometime.

Given the options you presented, as a former Microtech owner, I'd get a PFC. I'd put a Megasquirt in my car before another Microtech.

I agree. I feel like a religious zealot when I talk about my SM4, but it really is that good. In the 'low end' price range, I don't think there's a better choice.

Why is that? Reasoning, facts, something.

also curious. what sort of problems did you experience?

The Microtech is basically a sequentially injecting electronic carb. I think that it's one or two steps better than a Holley Pro-jection setup; at least the Microtech isn't TBI. If I were racing my car (e.g. WOT 99% of the time), then the Microtech would be great: it's easy to set up and it'll hold an AFR under load. The car I drive is on the street 99% of the time, and tuning the Microtech for all of the different running conditions just sucked. I never got the drivability of the ECU where I wanted it; I spent a lot of time datalogging in all sorts of situations, and the ECU always needed fiddling.

Once I went looking at other ECUs, I realized how much the Microtech lacks. It's 1980s ECU technology being sold to the aftermarket in 2007. It has no comprehension of engine volumetric efficiency (VE), so instead of doing what a computer is good for (math) it requires the tuner do a bunch of unnecessary work. It doesn't have a good suite of output controls to perform arbitrary functionality (e.g. complex boost control or water injection), and last time I used it the software sucked.

I moved to the SM4 because it had most of the power/control of a MoTeC M800, without the cost. I'm not a big tuner MoTec (I've only worked on a M48 in a 3 rotor, and looked at the new M800 V3 software), but I prefer the SM4's way of doing things. As far as the Megasquirt goes, at least they're using some modern fuel contro techniques; it's not all about pulse widths and correction maps.

As an example of what a modern ECU is capable of, check out this video (copied without permission, I just want to save the original host's bandwidth):

http://www.andern.org/alexander/movi...ronic1cell.mov

It shows how powerful the Autronic's internal VE modeling is. Watch the AFRs on the run with only one cell in the fuel table. I've done similar tests, and it does work this well in the real world.

I would say Haltech based on the feedback from my tuner. The E11 is supposed to be out of this world according to my tuner.

Like most ECU's people use here, 70s GM boxes LOL...

Haha I've owned 6 of them:lol: and have a bunch on the shop right now. I'm most familiar with the PFC but am also Haltech certified. I honestly prefer the Haltech but alot of people don't want to do the complex install or pay for it.

a7r -

thank you for your post. i have been agonizing over this EMS decision for about 2 months now and no one has given me any REAL input - despite my asking. the manufacturer's websites are useless. maybe my reseacrh tactics have not been the greatest, i entertain that thought, but i try. at any rate, you have provided me with the first bit of useful info, as opposed to people that spew without backing info and or those that simplt speak in circles.

now I'm getting some real information.
thanks guys and keep comming.

Sm4 price? ballpark?

Heres my opinion, I don't claim to be an expert tuner, or any expert on anything, but; if you can't control when each injector fires vs e shaft position, if you can't control each injector and spark plug individually, if you can't datalog and tune with multiple thermocouples( besides mutliple o2), etc, etc then you're better off using a carbureator!
