Megasquirt Engine management systems
Since 2001 the Megasquirt family of ECUs has been making the benefits of mappable fuel injection and ignition systems accessible to everyone.  With functionality usually only found on far more expensive systems Megasquirts have been used on everything from land speed racers to lawnmowers and pretty much everything in between!

Megasquirt/Microsquirt ECU
!
Microsquirt ECU. Injector shown for indication of size only
The Microsquirt is the latest addition to the popular Megasquirt family.  Controlling both ignition and injection in an extremely compact form factor is very capable system at a very attractive price point.  The Microsquirt is a great match for 4-cylinder engines and can also run V6, V8 and other engines too.
  • Two ignition outputs suitable for:
    • Direct drive wasted spark ignition on 4-cylinder engines
    • EDIS based ignition for 4, 6 or 8 cylinder engines
    • Control of distributor driven spark on all engine types
  • Two injection channels for either one low impedence fuel injector per channel or up to four high impedence injectors per channel
  • Coolant and air temperature sensor inputs
  • Oxygen sensor input
  • MAP sensor input
  • Throttle sensor input
  • Engine speed input
  • Fuel pump and Fast idle (IACV) valve outputs
  • Tacho output
  • Boost control
  • CANbus
  • Soft and Hard-cut rev limiter
  • Sealed case, little larger than a pack of cards
  • 35 pin ampseal connector and loom

Complete Microsquirt system for Ford Zetec/Duratec engines
!

A complete package of everything you need to install distributorless, 3D mappable ignition and fuel injection to your Zetec or Duratec engine.

The Microsquirt features two inbuilt drivers for wasted spark ignition should you wish to directly control the ignition, so our basic package   We recommend that rather than directly drive the coils that you use the EDIS ignition system.  With EDIS you retain full control of the ignition timing from the Microsquirt ECU but gain a "limp-home" ignition mode.  EDIS ignition also offers reduced electrical noise and an extremely tolerant crank sensor conditioning circuit.

This package contains:

  • Microsquirt ECU
  • Pre-wired 35 pin waterproof ampseal connector and stub loom - every wire has been printed with labels all along its length
  • Deluxe Loom kit and shielded wire
  • Pack of 7 new connectors for crank sensor, temperature sensors and injectors
  • New coilpack connector
  • New coil pack*
  • Coil pack bracket*
  • EDIS ignition module*

* As part of optional EDIS package

Tacho Driver
From
!
tachodriver130
Tacho driver module for coil-driven rev counters
Suitable for Megasquirt, Megajolt and many other ECUs the tacho driver allows you to retain your existing coil driven rev counter.  If you have a recent rev counter accepts the 5 volt output of most ECUs then you do not need one of these.
 
  • For 4-cylinder, wasted spark installations or two-cylinder independent coils use the 2-input version.
  • For 6-cylinder wasted spark or 3-cylinder triple coil installations use the 3-input version.
  • For 8-cylinder wasted spark or 4 cylinder coil-per cylinder setups use the 4-input version.
