Complete MegaSquirt-I V3.0 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. Beefed up injector drivers support both high impedance and low impedance injectors. Accepts tach input from a coil or a 12 volt square wave tach signal. Can be set up to work with variable reluctor (magnetic pickup) RPM input as well with a minor soldering change. 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. Ignition control outputs, or other features, can be soldered in. The schematics and source code are publicly available for those who want to customize their MegaSquirt.
