Jwt Ecu

for those of you who have JWT reprogrammed ECU's, did you have to do any rewiring of the main harness to fit the sr20de ecu into your Ga16de?

no i didnt rewire the harness and have not had any MIL's yet, except for the rear 02...but i dont have a cat or the sensor plugged in and my im not using the egr either. my car is a 97 and im using a 95-96 5spd ecu. i have no idea why JWT cant reprogram the 97+'s.

i believe this is what u are talking about.

thanks Javier,
That's exactly what I was wondering... so the sr20 ecu is a direct plug and play into a ga16de (with some tuning) How does Jim wolf handle the valve phasing? I know the sr20 doesn't have it... does having a sr20 ecu disable the cam phasing solenoid?

JWT can add an additional board in the ecu to control the valve phasing but they charge another @400-500 to do it. If you just get the normal JWT upgrade you lose the valve phasing.

Jim Wolf tuned the sr20 ecu to work with the b13 ga16de, that's why you would lose the VTC. Javier, i imagine you still have your cam phasing on your engine?

Post I see.

I understood that but valve phasing was throwing me off. I believe Eric A had the VTC module added but I thought it was less expensive than that, not sure.

Post Well

I hope they get it done soon, I will be sending them my ECU for that exact profile within a few weeks.

I assumed he was talking about VTC when he said valve phasing so I just used his same terminology.
