Megasquirt Adapter Boards

Megasquirt adapter boards fit in a gutted stock ECU case and connect to the Megasquirt using our relay cable or plug directly into the Megasquirt depending on the design. Depending on the board, these may be in kit form or sold as bare PCBs. To use one of these adapter boards, you will need to take a stock ECU and reuse its case and connector. The adapter boards generally require a few modifications to the Megasquirt; each adapter board has an article covering what mods it needs.

These boards are not designed/manufactured by DIYAutoTune.com but by various contributors to the MegaSquirt project in an effort to help streamline your MegaSquirt installation experience!
