I have a ECU/electronics question if anyone has knowledge in this area. Im preparing for a manual and 4WD swap on my 2002 SR5. I'm using a '95 Tacoma with manual hubs as a parts car. My issue is this - the stock 2002 4Runner ECU will have a permanent CEL with the manual trans. I'm also concerned that there might be fuel injection issues since the ECU thinks its still an auto. As I understand it, the 95 Tacoma ECU wont work, even if I repin the 4Runner wiring harness, because the 01/02 has a partial electronic throttle control. The usual choice for this swap is a 03/04 manual 4WD V6 Tacoma ECU, which works with the manual transmission and V6, but since Im using manual hubs, the lack of an ADD differential will confuse it and cause the permanent CEL again.
My question is mostly will the stock 4Runner ECU actually have fuel injection problems with the manual trans? If not, I might just deal with the permanent CEL. The other thing that was suggested to me was wiring resistors where the disconnected auto solenoids were, to spoof a signal and turn the CEL off. Would this work and how would I go about doing it? Could I do that with the 03/04 Tacoma ECU instead to disable the ADD CEL?
Its a bit of a mess, but if anyone has the info to help me out, it'd be much appreciated.
