Adapters and Flash Memory

The following adapters and Flash chips are available to ease the tuning process for the EPROM based ECMs.

 
SST27SF512 Flash chip. Can be used as a direct replacement for the 27C128, 27C256 and 27C512 EPROMs used in many GM ECMs. This is the Flash chip included with the OBDI-Tune kits. $6.00
G1 Memcal Adapter. This adapter is used on the newer GM ECMs that had the EPROM mounted in the full width Memcal module. This adapter bypasses the stock EPROM and allows you to use a replacement EPROM or Flash chip without having to modify the Memcal. This is included in the OBDI-Tune kits for the newer vehicles. $35.00
G4 Memcal Adapter. This adapter is used on the newer GM ECMs such as the 16183247 that had the EPROM mounted in the narrow width Memcal module in which the knock sensor circuitry is mounted underneath the EPROM. This adapter bypasses the stock EPROM and allows you to use a replacement EPROM or Flash chip without having to modify the Memcal. This adapter is included in the OBDI-Tune kits in place of the G1 Memcal Adapter when appropriate.

$45.00

G2 EPROM Adapter. This adapter allows the use of the SST27SF512 Flash chip in place of the original type 2732 EPROM used in the older ECMs. This adapter is included in the OBDI-Tune kits for the older vehicles.

$35.00

HDR1 Memcal Adapter. This adapter allows you to read an EPROM mounted in a Memcal with the Burn2 programmer or any standard EPROM programmer without having to remove the EPROM from the Memcal. This adapter is included in the OBDI-Tune kits for the newer vehicles.

$12.00

24-pin DIP Socket. This socket is used to replace the original socket in the older ECMs that used a type 2732 EPROM. This socket allows you to plug in a 2732 EPROM without the use of the PROM carrier and allows the use of the G2 EPROM adapter. This socket is included in the OBDI-Tune Kits for older vehicles.
