MicroSquirt with 30″ 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.

Only logged in customers who have purchased this product may write a review.

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?

    The MicroSquirt can run fuel and ignition on a single cylinder no problem. Reverse engineering a stock map is a bit of a challenge. If the stock ECU puts out OBD2-type codes, you could try this method from Andy Whittle's How EFI Works channel on YouTube. The MS2/Extra setting up manual also covers how to put together a startup tune.

    This unit would be capable of running a V8 with bank to bank fueling, wasted spark ignition, and at that point it would be close to the limits of available I/O. Stepping up to something in the MS3 family like an MS3Pro EVO would allow for fully sequential fuel and ignition control as well as control over the variable valve timing.

    Asked by Kiernan
    Answered by the admin

    The Ford V6 is fairly straightforward. You will need a QuadSpark ignition module if running the stock coil.

    An MS2 V3.57 or V3.0 would be a better choice for the TBI. We do not recommend MicroSquirt on GM TBI applications as its injector drivers cannot handle the current that the very low resistance TBI injectors use without current limiting resistors (which slow down their opening times) and does not have an output for the stepper IAC valve. The MS2 can run both of these out of the box and is a better fit for TBI applications.

    The MicroSquirt has only two injector outputs. Normally on a 3 cylinder 2 stroke, the system would use one coil that sparks all three cylinders at once, and the MicroSquirt software is set up to do this. It does not currently support 2 separate coils on a 3 cylinder unless they are triggered at the same time.

    It does, however, have boost control capabilities.

    This should work - just keep in mind the following limits.

    2. The MicroSquirt does not have an output for stepper type idle speed control valves. If your throttle body has one of those, you could use a '90s era VW 2 wire valve instead.

    We currently do not have an easy way of controlling direct injection systems - they run at around 50 to 100 volts, and need special voltage and current control circuitry. There have been some experimental installs with systems in the MS3 family using third party direct injector driver circuits, but this is highly experimental and not something documented well enough for others to duplicate.

    This would only be street legal if installed in a vehicle that predates emissions controls.

    Yes, you can trigger it from a distributor, no problem.

You will also need air and coolant temperature sensors, and a wideband O2 sensor will make tuning it a lot easier.

    Yes, this includes a short wiring harness.

    The MicroSquirt is basically a scaled down MS2. The PWM current limiting for low impedance injectors and the stepper IAC outputs are the main features that didn't make the cut. The overall I/O is somewhat more than a standard MS2, but you can add somewhat more I/O to an MS2 if you add enough mods to it. A MicroSquirt, by contrast, is a standard package that is only built one way.

    All you've got to do is wire it up and tune it. See the 4G63 / Miata wiring notes in the MicroSquirt hardware manual.

    Yes. If you run the coils in wasted spark mode, you will have ALED and WLED free for functions like boost and fan control.

    Yes, as long as you use a thermistor type cylinder head temperature. The MicroSquirt currently does not support thermocouples for engine temperature, but there are a number of suitable thermistor type CHT sensors out there.
