We’ve upgraded the MicroSquirt for tuners who want to push this box to the limits! The AMP’d MicroSquirt adds higher current capacity injector drivers, higher current capacity on its optioisolated input, and 4 user configurable option switches that activate on-board pullup resistors for applications that use hall or optical style crank and cam sensors. They can also be used to re-purpose digital switch (ALED and WLED) outputs to become logic level ignition outputs for applications that require 3 or 4 ignition outputs without having to solder resistors into the ECU case or wiring.
MicroSquirt is an entry-level, fully assembled ECU with varied applications targeting power sports, single cylinder all the way up to 8 cylinders with up to 2 fuel and 4 spark outputs. Over 40 different ignition modes are supported from mainstream applications like GM LS1, Ford Zetec, Bosch Motronic, and Chrysler Gen III Hemis to unusual modes like Renix Jeep and the Suzuki Swift GTI.
We recommend using the AMP’d MicroSquirt over the regular MicroSquirt for these scenarios:
When using 6 injectors in the 9-10 ohm range, or 8 or more injectors
8 cylinder distributorless ignition applications
Fuel only installations triggered off the negative terminal of an ignition coil
