This is an ECM for a wide family of General Motors cars from 1987 through 1993 model year. (See below). This particular ECM and PROM were removed from a running 1988 Oldsmobile Cutlass Ciera (this unit was used for troubleshooting, it was working fine when removed). The PROM code is ALZL, with is for the 2.8L V6 engine, 3 speed auto transmission (Code MD9) and final gear ratio code F17. You can install any compatible PROM from this family into this ECM. I downloaded the application list from a website so please double check the ECM part number to make sure it is correct for your vehicle. Thanks for looking!
