The MicroSquirt is an entry-level, fully-assembled version of the MegaSquirt 2 ECU. It features up to 4 ignition channels and 2 fuel channels making it suitable for running a four cylinder with full sequential ignition or a V8 wasted spark.
Additional firmware can be downloaded to allow you to use the Microsquirt as a plug’n’play I/O extension box for the MegaSquirt 3 or MS3-Pro ECUs.
