The OBDI Tuning Kits are complete packages with everything you need to tune your OBDI GM vehicle with an EPROM based ECM. (For 1994/95 LT1 and L32/L82 cars that have Flash based ECMs see our OBDI LT1 Tuning kits and OBDI V6 Tuning kits respectively.) The kits allow you to read the current calibration information stored in the EPROM, view and edit this information as needed and then program the replacement Flash chip included in the kit with your modified calibration right from the OBDI Tuner program.

There are two basic versions of the OBDI Tuner kits; one for the older vehicles whose ECMs used a type 2732 EPROM such as the 1227747 ECM, and another for the newer ECMs that had the EPROM installed in a Memcal.

Kit for older vehicles

Each kit for the older vehicles includes:

• C.A.T.S. OBDI Tuner Program
• ECM Definition File
• Flash Programmer
• G2 EPROM Adapter
• SST27SF512 Flash Chip
• 24-pin DIP Socket.

 

Kit for newer vehicles

 

Each kit for the newer vehicles includes:

• C.A.T.S. OBDI Tuner Program
• ECM Definition File
• Flash Programmer
• G1 Memcal Adapter
• HDR1 Memcal Adapter
• SST27SF512 Flash Chip

The installation of the 24-pin DIP socket in the kit for the older vehicles requires that the original socket be removed and replaced with the new socket so some soldering is required. No modifications are necessary for the newer vehicles.

Support for additional vehicle types can be added by purchasing additional ECM Definition Files.
