Description

The versatile MicroSquirt with 8′ Harness: Standalone Engine Management System, Transmission Controller or CAN I/O Expansion Module- Version 3.0

MicroSquirt with 8′ Harness is an entry-level, fully assembled ECU and universal 30″ pigtail 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.

MicroSquirt with 8′ Harness Transmission Control Options

MicroSquirt transmission control free firmware allows you to use MicroSquirt with 30″ Harness to control a number of electronic automatic transmissions (gearboxes). It can work standalone or integrate with one of our ECU’s over canbus.

Control applications: GM 4L60E I GM 4L80E I GM 4T40E I GM 5L40E (dev) I A341E I 41TE (dev) I Ford 4R70W I Ford E40D (dev) I Subaru W4A33 & more…

MicroSquirt with 8′ Harness CAN I/O Box Expansion

Microsquirt I/O Box firmware allows you to use a Microsquirt as a plug’n’play I/O extension box for MS3 or MS3Pro ECUs. It can offer a useful I/O addition:

-7 Analog inputs (0-5V variable)
-2 Wheel speed inputs (VR or hall type)
-2 Wheel speed (hall type) or ground-switch inputs
-1 dedicated ground-switch input
-2 high current PWM/switch ground-switching outputs
-4 mid current PWM/switch ground-switching outputs
-1 low current PWM/switch 0-12V output
-Perfect for capturing and logging vehicle speed and additional sensor data (e.g. pre- and post- intercooler temperatures, fuel pressure, oil temperature etc.)

To Use a GM 1, 2, or 3 Bar MAP Sensor with the MicroSquirt

In the illustration:

A is ground,
B is the sensor output signal to MicroSquirt,
C takes 5 Volts from MicroSquirt.

The pins are marked A-B-C on the sensor itself.

Product FAQ

Is this just for motorcycles and other small engines, or can it be used in a car or truck?

  • The MicroSquirt can run regular automotive engines; it’s not just for powersports applications. It is possible to run this on a V8 in wasted spark, although it doesn’t have very much I/O to spare for extra functions when using four spark outputs.

I’ve heard some people say it has two spark outputs and some say four. What’s the deal?

  • It was originally designed for two spark outputs, but the MS2/Extra code allows you to use WLED and ALED outputs as additional spark outputs. You will need to add resistors in the wiring harness for using them with most coils.

Is it waterproof?

  • No, but you can make it waterproof with a bit of RTV silicone around the edge of the case.

Are there other versions of the MicroSquirt for other functions? Transmission control or the “IO Box”, for example?

  • These all use the same ECU, just running different code to change its function and use it as a transmission control unit or I/O expansion device. See MSExtra.com for details.

Could I use two MicroSquirts, one running the engine and one running the transmission?

  • Yes. They would link up over their CAN networks to look like a single unit to the tuning software.

Where is this unit made?

  • They are built in the USA – electronics, harness, and case.

What do I need to tune this unit over USB?

  • You will need our external USB adapter.
