How did you get to that link from the front page? That has to be the most user unfriendly website I've ever used

You start at the front page and select catalog, by vehicle, GM, 82-92 Camaro, 82-92 Camaro engine, 82-92 Camaro engine ECM and Prom,

They have some Corvette Proms mixed in with the Camaro stuff.

The ones at this site and also found on ebay are made from v6 memcal they jumper the netress pin 56 to ground to change the cylinder select from v6 to v8. This means no limp home mode !!! The knock board on 90-91 corvettes does not work either. For anyone wanting to do this I can help. I have all the corvette , firebird, camaro .bin files for most tpi's. will reprogram for cheap...

I can burn a stock type chip if I have the .bin if you want to use one of those GP1 kits. That way you can retain the limp home mod.
