Product Description

MegaSquirt-II Engine Management System with 3.0 Main Board – UnAssembled Kit; Part # MS230-K_m4

The MS230-K kit includes everything you will need to build your MegaSquirt-2. The genuine B&G partial kit with PCB3.0, the Bill Of Materials, the case, pre-machined endplates and heat sink bar, even the tube of heat sink compound and a bit of jumper wire is included. All you add is tools, solder, and time!

MS230-K Kit Bill Of Materials (BOM) Includes:

  • All ‘Basic Components’
  • PWM Flyback Damping Circuit components
  • Hall Sensor/Coil(-) and VR Sensor Ignition Trigger Components
  • IGBT High Current Ignition Driver Components
  • Current Limiting Circuit Components
Legend for Kit Labels

The MegaSquirt 2 Standalone EMS is the latest product from Bowling and Grippo; Truly the dream ECU computer for the DIYer. This latest rendition can control fuel, ignition, stepper motor IAC, and more for your turbo, supercharged, or naturally aspirated engine. More information about MegaSquirt-II can be found at HERE.

MegaSquirt II includes all of the features and benefits of the original:

  • Onboard MAP and baro sensor for NA or boosted engines up to 44psi (upgrade over standard 21 psi single sensor)
  • Speed density or Alpha-N.
  • Use any injector – High or Low impedance.
  • Compatible with output from narrowband sensors and wideband O2 systems.
  • Log data on your laptop for later analysis.
  • Tuning software is free for download and regularly updated with new features.
  • Source code and hardware information is available online allowing you to customize things beyond the massive feature set already available if you choose.
  • Includes proper female DB37 connector and shell for your wiring harness.

Additional Features new to the MegaSquirt-II

  • 24 MHz HCS12 processor,
  • Fuel control to 1 µsec (100 times more resolution than MegaSquirt-I),
  • Ignition control (full spark timing advance control, dwell control, etc) for one coil/distributor (7 pin HEI for example) and Ford’s EDIS systems,
  • On-board stepper motor driver for IAC stepper control (this requires a few jumpers, included in the kit, to be added on the MegaSquirt PCB to connect the socket jumpers to the DB37 connector),
  • Ford PWM idle valve firmware support,
  • Built-in rev limiter, either ‘fuel cut’ or ‘spark retard’,
  • All tables are now 12×12 in size,
  • WBO2 AFR target table (in AFR units),
  • Independent dual-tables for VE and AFR target,
  • EGO feedback in wide-band mode is proportional to the difference between the measured AFR and the target AFR, the bigger the difference, the bigger the feedback step,
  • Spark advance table can have different rpm and kpa bins than VE and AFR tables,
  • 115,200 baud serial interface with MegaTune2.25+,
  • CANbus networking
  • Barometric correction amount and direction configurable in software, and provisions for:
    • barometric correction based on initial MAP reading,
    • independent 2nd barometric MAP sensor for continuous real-time baro correction, or
    • no baro correction.
  • TPS values for open loop and flood clear mode are user configurable,
  • MAP based open loop can be set as well as TPS,
  • Both TPS and MAP based accel enrichment is built into the code, you can configure the ratio of each,
  • Blended Alpha-N and speed density is an option,
  • 2 spare I/O lines for custom controls. (This is in addition to 4 lines for Idle stepper control if you don’t need this, or the Fast idle solenoid then becomes a spare if you do use a stepper motor.)

DIYAutoTune Kits and Completed Units also Feature:

  • Extruded Aluminum case with CNC machined flanged ends for easy mounting and a perfect fit!
  • The crystal and all nuts are glued in place to reduce sensitivity to vibrations. (Completed units)

Available Source code means Endless Development

As with the original MegaSquirt EFI system the MegaSquirt 2 is an open project allowing anyone to customize the hardware and code to meet different needs.   This firmware’s featureset has grown hugely and continues to be refined.  If there’s a feature you’re after, chances are MS2/Extra can do it!

As with all DIYAutoTune.com 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 as pictured below. 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….

Here’s a shot of a complete, assembled unit.

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
    • 4 bar MAP sensor (onboard)
    • Barometric pressure sensor (onboard)
    • Oxygen sensor - narrow band or wideband with external controller
    • Throttle position sensor
    • On/off fast idle valve
    • Stepper fast idle valve
    • 2 injector output channels
    • Tach input - Hall effect, optical, or VR sensors supported
    • Single direct coil control spark output

I've seen a mention of an MS2 Daughter Card. Do I need to order that separately?

  • No. The MS2 daughter card is included as part of this kit.

Does this kit include a MAP sensor?

  • Yes, there is a 4 bar MAP sensor included. It is a small circuit board in a static resistant bag and will not look like a conventional GM MAP sensor.

What firmware does it have?

  • The daughter card ships without firmware. You will load firmware during assembly.
