HELP with sy/ty eprom


New Member
I have a 93 sy/ty engine i need the eprom for. i have the correct ecm, but don't know where to find the eprom, any advice would be cool
I thought I had one for ya, but unfortunately its not for the '7749, it's for the '7730. If you come up short, or find one where they are asking way too much for it, I would seriously consider the SFI-6 in it's place...
you can still get those from gm. Do you have the chip carrier with the knock module and calpak ? it will be blue and about 4 inches long. Th chip itself plugs into that.

if not you will need the entire assembly.
