Hi, all. I'm an old school hotrodder and I'm more used to butt-data than real data but there are a lot of similarities. Ran across gearhead-efi while on a quest to interrogate the CCM on my odometer challenged '92 ZR-1. I know you guys are LT1 but I saw the 'Corvette CCM Reverse Engineering Anyone?' thread and I was hooked. You guys know a lot of shit.

OBD1 is cool. The car supports a lot of diagnostics through the aldl and DIC, so I'm just chipping away.
