I THOUGHT a simple efi 350 in a S-10 would be so easy. NOPE!!
Started with 2002 3500 Chevy Express L31 (EFI) 2156 OS/ that had an automatic tranny. Well, I went with a NV3500. I have seen and flashed a -L31 manual .bin- to it, however when I opened it in tuner pro IT IS A STOCK .BIN. So, I found 3 .ctz files (similar to .bin, yet for EFILive instead of TunerPro). These are for Mexican Chevy Trucks that had the L31 with a manual tranny. I have no way to convert them to .bin files.
My issue is the 2002 L31 did not come with a manual tranny. Here are the files I have gathered.
