MegaSquirt 2 (MS2) is the second generation of MegaSquirt Engine Management Systems, targeting engines with semi-sequential or batch-fire fuelling and wasted spark ignition. The MegaSquirt 2 shares the same software as the MicroSquirt but most options will require hardware customization. The software 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 batch fire fuel injection and up to four channels of logic ignition. Over 40 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.
