use this list to find your ECM/chip locate your engine/platform in the left side menu, locate your year, then the corresponding ECM number...use the the ECM number listed in the lower main menu to find the memcal/PROM that was used with that particular ECM/ vehicle application This page lists the several generations of GM engine, powertrain, and vehicle control modules which are characterized by having a single EPROM or EEPROM containing both the vehicle calibration and program code. This page does not cover the older C3 generation of ECMs. It also does not cover any flash based control modules. Items in italics are unverified.
