Complete MegaSquirt-I V2.2 assembled engine control unit set up for fuel-only operation. This ECU has two outputs for bank to bank fuel injector control, an on/off idle speed control, and fuel pump control. Accepts tach input from a coil or a 12 volt square wave tach signal. Built in 2.5 bar MAP sensor can read up to 21 psi of boost. This ECU allows for real time tuning of your fuel and data logging to a laptop. Perfect for basic fuel injection conversions on a carbed motor where you're happy with the existing ignition setup, or can also be used to control additional injectors to add fuel under boost for a turbo motor. For ignition control applications, we recommend starting with a V3.0 or V3.57, although it is possible to modify this unit for ignition control, just a little more involved. The schematics and source code are publicly available for those who want to customize their MegaSquirt.
