Hello! I'm here as I bought a '94 Corvette recently and I intend to do some PCM tuning and trouble shooting. My car is a 6-speed so I intend to disable the skip-shift and read the DTCs which my CCM won't show me for some reason. I know I have a DTC set as my cooling fans run continuously and the dash is showing "SYS". I bought the factory service manuals off EBay which already helped me with the climate control. I have a 16-pin male ALDL connector and some female DB9 connectors on the way to build an adapter; I want to use the FTDI USB to DB9 serial cable I already own.

I'm a telecommunications electronics tech so the hardware side of things doesn't bother me, but code puts me to sleep. I greatly appreciate what coders do for us so thank you.
