If anyone has time- need some direction on a car dropped on me. I will try to filter out non relevant work and post what I know.
2012 camaro l99 with auto trans. Customer had a separate unknown shop install 2012 ls3 with manual transmission.
Original l99 computer was reused with original operating system- tuned and tweaked on to make it start. Ran horribly , back fire, several dtc codes, no cam signal, no clutch pedal signal
BCM and ABS original as well
I received car- pulled diagram of harness- one by one did pinout from pcm to each sensor on engine can the previous installed clutch pedal with sensor. The harness diagram of l99 vs ls3 in that year very similar minus the dod. Cam sensor wires were wrong- fixed the back fire. verified clutch pedal wires are correct to pcm pinout.
Now for the crazy tuning. it would not idle and any snap throttle would allow rpm to fall to far down causing it to stall. the final airmass table was zeros in the low rpm range. I changed it to 5g/s. 90 percent resolved.
DTCs: i still get u0101 (for missing tcm) out of the bcm, p0600 1 time, several random light and accessories malfunction out of the BCM.
ABS- u0101 , traction control on .
When driving - it will take of like a jet, then go to reduced power mode.
My questions:
1)What do i need to restore clutch pedal sensor function? I was told I need a manual operating system to be flashed by gm mdi2 so all 8 layers of coding change? Can anyone verify this? I have changed the trans to manual in hpr tuners but make no difference.
2)Do I need to change BCM or ABS module? Can it be disabled? I did disable any reporting in the engine diag section of hp tuner on the tune- still get the u0101; BCM hp wont touch.
3) I found a 08 ls corvette manual trans tune on this website. do you think writing this with mdi2 will be compatible?
