Flash Prom vehicles are unique in that their ECM is specific depending on the VIN number. The name "Flash" comes from the fact that the entire memory chip is erased and reprogrammed without removing it from the ECM. It's less expensive, more reliable and has increased memory capacity.

Flash PROM vehicles listed in YELLOW are the current OBD1 models we reflash and modify for performance applications. Anything listed in white can be upgraded to the latest GM calibration at a modest cost at our shop.
