The Microsquirt is a small (2.75 in. x 3.75 in) Engine Control Unit that comes completely assembled, in a rugged, weatherproof aluminum enclosure, with a high quality Ampseal connector and wiring harness, one end terminated to an Ampseal plug and the other open-ended, for attaching to the engine sensors and components. This unit is built with the MS II/ HCS12 processor and runs the same software - also downloadable for easy (and free) upgrades.

MicroSquirt v2 is now shipping. Details of the (minor) improvements in the new version can be found at http://www.microsquirt.com/viewtopic.php?f=87&t=23064.
