Hello everyone, i'm from italy and quite newbie with HP tuner.
I have a 2005 LS2 from a Corvette with T56 transmission and E40 ECM. I fitted the engine on a Jeep with TH400 transmission. I got a stand alone wiring harness from a supplier and start to modify the ECM tune erasing VATS, o2 sensors, evap system etc.
The throttle body and the gas pedal are the original installed in the car so it match.
When I got the wiring harness form the supplier, I've installed it but the engine won't start, no fuel pump signal. After some test I check the pinout and the blue connectors was completely assembled upside down from the supplier. I've mirrored the pinout matching the correct one. Now the car start, stay at idle but wont accelerate.
- I tried to accelerate with VCM Scanner on the idle function and it work fine.
- I checked the TPS on the scanner and the value increase when gas pedal is pressed.
- I checked the volts on APP1 and APP2 at the gas pedal and it works correctly.
- The throttle body seems work correctly
This is my first ECM so I'm not sure to have erased all and the correct DTC's or if any other functions have to be enabled or disabled.
Here my OEM tune got from ECM and the modified currently on the car.
Please if some guru can watch it and let me know his though it will be very helpful.
Thanks
