MegaSquirt 3

The MegaSquirt 3 (MS3) is ready to support a wide variety of engines out of the box, with the ability to control anything with one to eight cylinders with sequential fuel injection and sequential ‘coil on plug’ ignition, a V12 with semi-sequential fuel and wasted spark ignition, or a four rotor Wankel with separate leading and trailing ignition outputs. Over 50 different ignition modes are supported, from mainstream applications like the GM LS1, Ford Zetec, Bosch Motronic, and Chrysler Gen III Hemis to unusual modes like Renix Jeeps and the Suzuki Swift GTI. The software includes many ‘race’ type features, two stages of progressive nitrous, water injection, closed loop boost control etc. Vehicle speed sensing, logging of EGT (with external hardware.)
