New LT9c
 
1 Attachment(s)
New ecu will apparently be available in 8 wks and have 32 x 32, save to disc and map sensor option.

it's nice to see they addressed many of the issues with their old rocks, unfortunately we have to buy a new ECU to get beyond those limitations.

took them long enough... suppose they finally saw the decrease in sales enough to finally do something about it.

wonder if it works with their current LT8 or LT10 harnesses. building a new harness isn't that big of a deal but it would be nice to just swap out the ECU and be done. also curious what map sensors are supported and if they are configurable or if it is limited to their own sensors. tired of brick walling customers into buying things from them to upgrade things that not a single other EMS walls people into buying with their tag on sensors or drivers.

"listened to the long time loyal customers" makes me gag.. more like they have seen these long time customers,,, i rate myself as one of the first customers back in the first analog , digi, MT/LT days

... leave in droves due to lack of fulfilled true laptop capability and lack of user define

now they are well behind the 8 ball.. 32x 32.. user define and lap top save and share has been staple everywhere else for 5 years

lets just hope harness and build quality have come up to the line too

If it's anything like the LT10c it will be hugely sensitive to RFI. The one thing Microtechs were known for was their lack of RFI related issues - but due (I assume) to a hardware change on the board that seems to be a thing of the past. You know there is a serious problem when the ECU switches itself off for a split second half way through a dyno pull! Not just one dyno pull but almost every dyno pull. And what's worse the same thing happened on 2 different cars with 3 different ECU's, and 2 different igniters. One FD, and RX3. The only thing in common was the LT10c's.

Needless to say I won't touch another new Microtech.

lambda feedback o2 correction ?.. target AFR correction? .. ..

saturated only injectors

look close people and be sure it will suit your current and future needs before you see the price..

for about $200 more , some other ecus bring options that are 32 x 32 for fuel AND IG .. with no limit on injector choices ,, and have target correction AFR are have no limits on user config and map define

bang for buck this microtech doesnt look too bad if you have an oldschool conversion
.. its aimed clearly at the haltech sprint market but isnt quite everything everywhere

but anything more complex or for future expansions i would be looking closer at other options
.. stuff like e420D is only $200 more and falls just short in capabilty of the major offers at twice the price
,, and happily runs stuff like complex rx8 staging and ignition triggers at the tick of a box

Load and save maps to Hard drive, as well as to a text document.

These sound like options that can simply be had with new s/w.

Maybe those of us with older ECUs will benefit as well...

If Microtech truly listened to their long and loyal customers they would have:

-delivered software updates to the LT8s as promised
-updated the tuning software to something one would expect in this century (including save to disc)

While it's great they've released a new ECU, it's like the new iPhone 5: obsolete before it's released.

There doesn't seem to be any info on their website on this new ECU, but based on the info posted in this thread, it's a non-starter.

High impedance only? Makes it fairly useless to high HP rotary people running big low impedance injectors.

A good number of outputs for a basic setup but no mention of idle valve control.

Closed loop operation? Target AFR table? Quick/auto tune?

How about AE settings? Can it compare to the other ECUs on the market or are we stuck with "Pump1" and "Pump2"?

Hopefully they've fixed the terrible and rough interpolation in the matrix table!

I sure hope they've discarded that ridiculous distributor based ignition table in favor of a proper 3D table that every other ECU has had since...um, forever?

3D temperature correction as opposed to just a linear correction?

And if it doesn't plug into the LT8 series harnesses, then it's not much use. If I'm modifying harnesses on my car to get rid of the LT8s (which is a certainty as soon as I'm done my Cosmo) I'll be installing a P1000 which is just about $200 more expensive (already mentioned in this thread) and has 10x the features.

It's worth mentioning that MS3X is cheaper and far more capable.

dam why only high impedeance drivers doesnt make sense?

Aaron Cake 10-06-12 10:17 AM

Google "microtech lt9c" and the only thing that shows up is this thread and threads tagged as "lt9c" on this forum.

Seems rather odd there's no announcement on the Microtech website, forums, nor anywhere else.

I need to buy something soon but from the History I worry that if there are glitches or issues, will they come to the party or leave us with our pants down as they did before. :scratch:

WLD 07 05-22-13 04:27 AM

Well it's 6 months after they said it would be released...... So they maintain their reputation.....:icon_tdow

garyc 05-26-13 04:24 AM

I won't be buying one of these that's for sure I'm now researching Link G4 and Adaptronic it would seem that the latter might be the one to go for. Has anyone got any comments on the G4 or the 440 from Adaptronic I will add the innovate MTX L




The other question I have is on the oil pump
I have a mechanical pump that’s not from my series 5 does that matter
The way I have connected it is via a linkage that goes from the pump to the throttle so its at full on full throttle if that makes sense to you.
Other issues I have is my instrument cluster as it’s from the original car I need to link up its oil pressure revs temp etc. what I will also need is boost pressure and I would also like to have fuel air ratio from a five wire lambda sensor is there anything more that you would suggest and do you sell stuff like that.
I have sent some pictures of my build and some of the components

I've had my series 6, LT8s ECU for years and after speaking with John three times
regarding a CAS issue; I see they finally made a change to their
wiring diagram... Hope they offer better technical service in the future.

waztted 05-26-13 06:09 PM

good to see they are still ignoring voltage compensation !!! theres no way id buy another microtech

because they are just distributors ... they are not the actual "microtech" guys that everyone would love to speak to. they just try to feed anyone with what ever they wanna hear

WLD 07 05-27-13 03:53 AM

???

I spoke to Microtech at QLD Jamboree in September and they said 8 weeks.

cody27 09-02-13 06:29 PM

It's out, and it's mostly the same old shit in a new box. LT-9c Series

garyc 09-03-13 03:26 PM

Any one want a Mtx 8 cause I'm running Adaptronic 440 select and loving it. No comparison with self learning capability and it runs like a dream. My advise is don't waste money get the best that you can its well worth it especially if you got back up like I'm getting from Adaptronic

RotaryEvolution 09-03-13 04:22 PM

seems like a waste of time with these. the only thing i can see that seems ok is the fact that you can change map sensors now... woo woo!

still have to pay $600 for the ability to log a simple wideband which is a 15 year old standard now(and stuck with their sensor mind you, that i'm sure they charge bank for replacements of).

the worst thing is the ECU is still fairly hardware locked, most changes have to go back to australia to be performed. fuck that.


i would also probably suggest the adaptronic if they have a PnP for your car. still wish they had one for the FCs, we get screwed yet outnumber all other rotary cars in production.

"the cheapest ECU on the market" should also say "with the least amount of options on the market"

after 6 years the hand controller started wigging out on my LT8, suppose it is time to move on to something that was modern even in the year 2000.

WLD 07 09-08-13 03:41 PM

Microtech are a joke. The LT9c is still only 16 x 16 despite saying it would be 32 x 32 last year.

Still over promising and under delivering. :scratch:

Aaron Cake 09-15-13 10:21 AM

The resolution doesn't matter so much in most cases, but the interpolation between bins definitely does. Original MegaSquirt 1 is only 12 x 12 (if I remember correctly) but far smoother interpolation means it runs about a zillion times smoother than an LT8s or other Microtech with higher resolution.

WLD 07 09-16-13 06:54 AM

I agree Interpolation is important, but it doesn't help if the values aren't linear which is where (user definable) higher resolution is required.

waztted 10-16-13 06:18 AM

lol wanna know something funny !!

yes the lt9c have save to file functions..

but you cannot load a tune via the function so its effectively useless !!

Yes it is!
I have one and i am a little confused.
LT9 only runs high imp injectors and i have low imp injectors.
I asked the sales rep if i can run resistors or a driver box and use my low imp injectors and he said that it wont be possible that it will damage the injector drivers on the lt9..........does anybody have any ideas if this it truth or not.I seen low imp injectors running on haltechs with oem resistor boxes or injector controllers with no issues!This is the only thing holding me back and i dont have a answer for sure!

Im not sure how that would damage a injector driver its the same thing with the power fc. Resistor boxes is just a conversion to utilize from high to low impedance. But heck someone chime in??
