C3-C4 Corvette EPROM & Memcal Chip Codes 1980-1995

C3-C4 Corvette EPROM Memcal Code List 1980-1995

What is an EPROM/Memcal Chip?

An EPROM or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. EPROM refers to chips which are attached to the Engine Control Module (ECM) from 1982 to 1985. GM changed the name of this chip to a Memcal chip in 1986. The Memcal chip is attached to the Engine Control Module (ECM) on 1986 to 1993 Corvette models and in the Powertrain Control Module (PCM) on 1994 to 1996 Corvette models.

What does the EPROM/Memcal Chip do?

The EPROM/Memcal chip contains the “calibration” data which is specific to a Corvette model. This calibration data includes the engine type, transmission type, rear end ratio, etc…,
