Just as the title states, trying to find out if I can get a segment swap done from a L31 350 to a LQ4 or LQ9 6.0L on my 0411 PCM which started with 12212156 O/S converted to HP Tuners 1281002 R/T MAF Enhanced O/S. I have the PCM in my 1997 Express van with the L31 and looking to do the EFI Connection 24X reluctor ring and 6.0L LS coils. The factory L31 ignition system is JUNK and ready to have something that does not have a case of cold/wet weather misfires.
For most segment swaps you need to have the original OS, do the segment swap and then re-upgrade the OS.
Thats what I was hoping to avoid though because that would cost me $100 in credits for the same VIN PCM and same operating system. 12212156 was also used with a 6.0L.Quote:
