So I have a 97 Supra which was a 5 speed NA but now has a TT engine installed. All was running great but now it is refusing to start.
To start id like to confirm I have not FCD or Speedo converter on the car, these seem to be the common causes for the problems I'm having.
I was running the Auto ECU the engine came with and was fine until one morning it started but then died immediately after. Didn't matter if you tried to hold the revs it still died as the revs just drop off.
Checking the error codes I get 31 which is air flow sensor? Where is this as when you research online most of it is from the american forum talking about the AFM which I don't have on the JDM engine.
Next I tried fitting a Manual TT ECU as I had read this helped someone with a similar problem. Now with this connected it does actually run and stay alive but it is VERYYY Lumpy it also now has more codes.
The Error codes it has with this are 27, 31 and 35, now if I am not mistaken this is 27 - Sub Oxygen Sensor, 31- Air flow again and 35 - Turbo pressure sensor.
Does anyone have any ideas at all what I should be looking at here?
Its got to that point I'm almost ready to part it out.
