I just finished a swap in for a friend's 99 G20 with a U12 Sr20det. We used the factory harness along with all the sensors such as distributor, knock, tps, throttle body, IAC, from the 99 into the the U12 sr20det. Ecu i am running is Calum's B14 daughterboard and my own program. THe car start up but i cannt got a TPS voltage via consult so i can adjust it. I am getting RPM signal, airflow signal, but TPS is showing at zero. Can someone help?

have u measured the tps voltage at the ecu and see if the ecu is getting any voltage? if not, do that

Did you modifiy the harness to run a pre '98 ECU? I remember something about messing with the boost solenoid inorder to see TPS voltage.

Hi, i did modify the harness the run a 96 ecu according to JWT manual. I modified the o2 ground and signal that's all. About modifying the boost solenoid? I Didnt touch any of that. I didnt know the 99 G20 has a boost solenoid.

Ok i found out i installed the TPS wrong. The hook on the tps didnt latch on the to throttle body so the whole time the tps hook didnt move when i step on the gas pedal.
