Overview

Standalone engine management system based on Megasquirt MS3x Processor and firmware with enhanced inputs and output ports.  This device is customizable, you can choose the features you need and add it to be built, however there are some basic features which are 2 trigger inputs, 4 analog dedicated inputs (CLT, IAT, MAP, TPS, O2),  5 analog/digital inputs,  5 digital/frequency inputs, 5V ref voltage, USB connectivity. The other feature the device capable of are controlling sequential injection on engines up to 8 cylinders, or semi-sequential up to 16 cylinders, combined with direct fire ignition for engines up to 8 cylinders or wasted spark ignition on engines up to 16 cylinders, The 4 bar internal MAP sensor can read up to 44psi of boost, 2 Programmable knocking detector circuit can be used to adjust the ignition timing, and internal switch to pull up resistor.  and knocking) and 16 low side outputs to drive injectors or any solenoid valve.  Bluetooth or WiFi as optional connectivity, CAN bus, SD card for logging, Real time clock.
