I did a swap in a truck that comes stock with an Ly6 and didn't look at the serial number of the motor I put in it until i already had it in there and now it has a l76 and it just doesn't idle right so I bought the MPVI2 and now thats were im stuck on what to do next.
What year?
Year of truck? ECM Type? Tune and log file?
2010 Chevy Silverado 2500, Stock Ly6 ECU.
2010 Chevy Silverado 2500
Hmmmm... Maybe find a 2009 G8 GT tune, copy over the engine settings ONLY and write calibration to get started. DO NOT WRITE ENTIRE or LICENSE THE G8 TUNE AND WRITE IT? If youre not familiar with this, DONT TRY IT. Rather get someome to help you.Quote:

Ill see what I can do.Quote:

The L76 have AFM/DoD too where as the LY6 is just VVT.
Did you delete the AFM/DoD system?
he can disable that stupid DOD with the software right? and cant you disable the VVT also?
Yes.
I asked because his LY6 harness won't have the stuff for the AFM system, so if that it not disabled it won't run correctly.
I meant to tell the OP that. I should've known better since I own an G8.Quote:

Post the stock tune file I will make some adjustments for you since I have an MPVI2 send it back.Quote:
