My Airtrek is a 2005- It was the last one to be shipped to New Zealand.
What you might want to do is flash the car again with the rom image, start the car(or try to) and see if you pull any codes. This may give you an idea of any problems.
I dont have the pinouts with me for a couple of days, but I can PM you @Monday US time with them.
That will be the easiest way, because if the plugs are the same as the 3G(which im sure they will be) there may only be a couple of pinout swaps to be able to run a GTA or Airtrek ECU.
You wouldnt be able to PM me a copy of your 3G rom image and definition(if I dont already have it)?
It would be interesting to see where the auto maps are in that ecu.
The late model airtrek carries a different head from early models. The valves get closer to the evo side, but the exhaust are 1mm smaller on the airtrek
I would have to disagree with the GTA computer not working- but it maybe something to do with how old the wagon is.
I have plugged in and used a GTA ecu in my 2005 Airtrek with ZERO problems. I havent kept it because it ran on Evo7 Kernal and my stock one runs on Evo9 kernel and has quite a few extra maps for the gearbox.
There are only a couple of pins on the ecu that go to the AYC computer and these pins are empty on my loom.
No the Evo ecu dont fit-wrong plugs
What type of gearbox are you trying to control?- you may not be to control anything other than an exact GTA/Airtrek turbo gearbox.
Did you put FFFF into the immoboliser in ECUFlash or copied the number from your rom?
The best bet would be to piggyback an Evo 8 ecu onto your current one and continue to use the current one for controlling the tranny.
If you have a DSM you will have access to all the wiring diagrams. You will just need to share inputs that both units require like TPS Speed Throttle Position etc. There are not that many to share and it will run like a champ.
Ive done a similar exercise with a Tiptronic Lancer 1.8 Turbo- worked great!
Trying to do anything with the GTA or Airtrek Turbo ecu will be a lot of hard work.
I am about 2 weeks from finishing upgrading to a GT3540 and am targeting 10sec 1/4. There are so many things that the ecu does with the gearbox that no one else has found (as far as I know) and I wont be releasing ANY info until the 10second run is done.
Oh yea- we are doing it with Stock Block/Head (with headbolts)- Stock ECU and MAF- Stock Auto Box with a few adjustments physically and electronically. The only thing that may cause problems is loss of power through the stock maf, but I have a GM 3" if needed.
PM me if you need any further help.
hi my name is joanne can u tell me if the airtrek ecu works on the evo 4 engine i have it in a mit lancer?
