This guide is going to focus on the basic, as well as intermediate information of tuning GM OBD1 ECU's used in 60º V6 vehicles. Notice, 94-95 OBD1 vehicles are mostly unsupported. Only the 94-95 DOHC have a removable chip and some support, albeit not much. The 94-95 A body 3100 also has some MEMCAL chip setups, and Tuner Cat is the only known definition for tuning it. I recommend getting a Megasquirt or other aftermarket computer if you have a 94-95 3100 engine. You could also convert to OBD2 or a better supported OBD1 computer.
