Recap what going on with my car. I took my car out of commision to installed suspension parts, 2G Maf, chip flash with Tuner Pro for 550cc injector. The car was a runner with 450cc injector prior to this project.
Now the car has:
550cc Evo 8 injectors
Big 16 Turbo
2G Maf 501
I'm not new to this tuning stuff, this one stump me. This what I have done:
-I have all new temp sensor installed thinking that it could be bad.
-Rewire ECT wire, it was brittle and normal for these car.
-Rewire for 2G MAF.
-2G TPS sensor wire in.
-Checked for vacuum leaks and pressure leaks.
-Replaced all throttle body seal.
-Replaced ISC motor.
-Triple check all my wiring that I modified and they all correct to ECU pinout.
I tried to start in small increment on this project and didn't want to get crazy.
The issue i'm having is at idle and after rev. The car will die after high rev. I'm narrowing it down to ECU. The closed TPS signal is there when the ECU power up and after it started the signal is an open. The only thing that control it is the ECU. I did do all my pinout verification and wiring resistance test. They are good.
What do you guy thinks?
