Does anybody have any diagram for swapping a 1994 g20 (p10) into a 2001 g20 (p11) car. Which color goes to which would be perfect, please help me out on this one!!

2000-'02 G20 ECUs are 32bit, '99 and down are 16bit, they are not compatible. It might be possible if you used the complete '94 G20 engine harness.
The '00 and up P11 that swap in DET's use the '99 P11 16bit ECU and harness to run the motor I think

Someone else care to chime in?

I have the 1994 ecu and plug in plus some wire out. I know it will work just gotta figure out which wire goes to what.

Here you go

Good luck and report back how it goes. I plan to do the same swap.

I used that and i am left with a bunch of wires it says to hook up but are not there, alot that seem important!

sorry to hijack this thread, ive done some searching around but nothing confirms. i have a UK spec 10:1 roller rocker DE (low port, obd1, non egr) would a G20 ecu yeld an increased rev limiter? currently my UK DE tops out @ 6950rpm.

sorry if this is a dumb question, its not tried in the UK
cheers in advance david
