Product Description

MegaSquirt-I with V2.2 Main Board

MegaSquirt programmable EFI Engine Management System from Bowling and Grippo. Install fuel injection on anything from a single cylinder lawnmower engine to a fire breathing V12, and anything in between! This kit is easily the biggest bang for the buck in the standalone EFI arena. You build it, You tune it, you drive it. The sense of accomplishment is amazing as are the results when you finally get your car dialed in just right after spending who know how long messing around with piggybacks and other ‘hacks’ that just don’t get the job done right. Stop wasting time and money and MegaSquirt your ride! You won’t regret it.

This is our entry level system. It can control two banks of high impedance injectors, and fuel-only control or ignition systems that use a square wave RPM signal and a logic level output signal. Examples of ignitions that work well with this one include GM 7 or 8 pin HEI, Ford EDIS or TFI, Toyota VAST, and Mazda Miata ignitions. If you need to run low impedance injectors, variable reluctor (inductive pick up) ignitions, or direct coil control, or are thinking about stepping up to an MS3 in the future, we recommend starting with a V3.0 board.

This kit includes everything you will need to build your MegaSquirt ECU. Just add tools, solder and time! (Black Anodized Case is included, it’s wrapped up under the PCB in the pic above, EVERYTHING is include to build the ECU) Mod kits for additional hardware features are sold separately.

As with all un-assembled kits, the quality is second to none. Everything is meticulously organized and labeled to help make your ECU assembly go as smoothly as possible. For example, each of the above bags contains a certain type of part, one with all of the resistors, one with diodes, one with capacitors, etc. Inside each of these bags the parts are further broken down and labeled in their own individual baggies. We even go so far as to put the components in numeric order to make finding them easier. We’ve really tried to think of everything….

    Very fast shipping! Assembled it in 5 hours, the next day my car had started with Megasquirt! :)

    Excellent kit, great website. I will be ordering anything else I need from these guys here. First time putting things on a PCB, easy to follow along what needed to be where.

What inputs and outputs are provided with this kit?

  • It includes the circuitry needed to connect to the following sensors and outputs:
    • Coolant temperature
    • Intake air temperature
    • 2.5 bar MAP sensor (onboard)
    • Oxygen sensor - narrow band or wideband with external controller
    • Throttle position sensor
    • On/off fast idle valve
    • 2 injector output channels
    • Tach input - Hall effect or optical sensors supported

Does this kit include a MAP sensor?

  • Yes, there is a 2.5 bar MAP sensor included. It is a small UFO-like item in a static resistant bag and will not look like a conventional GM MAP sensor.

When should I use a V2.2 board, and when is it worth stepping up to a V3.0?

  • The V3.0 is significantly more flexible. For a new build, a V2.2 could be cost effective under the following conditions:
    • You will be running high impedance injectors.
    • You will be using fuel control only, or one of the following ignition systems:
      • Ford TFI
      • Ford EDIS
      • GM HEI
      • VW Hall effect distributor and "139" ignition module
    • You do not need any other outputs beyond fuel and ignition control.
    • You do not intend to upgrade to MS2 or MS3 in the future.
  • If your plans include any features beyond this, starting with a V3.0 is likely to be a better option.

What firmware does it have?

  • The processor ships with Bowling & Grippo V3.0 code. It is easy to upgrade to MS1/Extra code during assembly.
