So I just swapped an l-31/0411 pcm into my Trans Am and of course it won't start. Using a timing light I found the ignition timing was firing at 0 degrees TDC which explains why it doesn't want to start. Using the EFI live scan tool I confirmed that was no error the PCM is actually calling for 0 degrees of advance.
However, after looking through the tune file I see no reason for the PCM to call for 0 degrees of timing? According to the "Spark Timing When Cranking" table it should be calling for like 13 degrees of advance? I even tried changing the "Minimum Spark Advance", which according to EFI live's description is the absolute minimum timing that the PCM will ever allow, to 10 degrees and it's still calling for 0 degrees of timing?
The tune is essentially a stock 2002 l-31 express van tune with the exception of things like the VATS being disabled. I'm totally new to EFI live so I'm hoping I'm just overlooking something here. Any ideas as to what is going on?
