Description

Included is a MegaSquirt-III Engine Management System w/PCB3.0 – Unassembled Kit Part # MS330-K

This MS330-K_BL kit includes everything you will need to build your MegaSquirt-3. The genuine B&G partial kit with V3.0 PCB, everything in the standard Bill Of Materials (note: BIP373 coil driver is sold separately as most installations do not need this), the MS3 daughter board kit, the case, pre-machined endplates and heatsink bar, even the tube of heatsink compound and a bit of jumper wire is included. All you add is tools, solder, and time! The MS3X Xpander board is sold separately and allows you to fully take advantage of the MegaSquirt-3, including 8cyl sequential injection, 8 ignition outputs allowing 8cyl coil on plug, nitrous control, and more.  Add a tuning cable to your order if you don’t have one already. 

MS330-K Kit Bill Of Materials (BOM) Includes:

  • MS3 Daughter Card
  • All ‘Basic Components’, including 2.5 bar MAP sensor
  • PWM Flyback Damping Circuit components
  • Hall Sensor/Coil(-) and VR Sensor Ignition Trigger Components
  • Current Limiting Circuit Components

The MS3 daughter card on its own will give you all these features and more:

  • VE and ignition tables are now both 16 x 16
  • 0.1% steps on VE table, 0.1 degree steps on ignition table
  • Socket for an onboard SD card – no laptop required for data logging  (SD Card not included)
  • Built in USB port
  • GM stepper IAC control
  • Closed loop idle and mixture control
  • CANBus communications for interface with GPIO Board, IO Extender, or other devices
  • Staged injection
  • Native support for many different OEM trigger patterns

The MS3 also gives you a starting point for even more expansion. You will be able to connect the headers on this board to additional hardware, such as the MS3X board to enable features like these:

  • 8 channels sequential fuel control
  • 8 channel sequential ignition control
  • Individual fuel and spark trim for cylinder by cylinder tuning
  • 2 and 3 channel PWM IAC control
  • 2 stage nitrous controller
  • Table switching for multi-fuel engines
  • 2 step launch control
  • And more!

  1. 5 out of 5

    Excellent attention to detail with this kitI've assembled three of these now - one is currently running my turbo swapped 260Z. I have to say that the organization, packaging, and labeling of all the small parts is outstanding. With the excellent assembly documentation, it makes building up this DIY kit as easy as it could possibly be. I appreciate that this kit let's me "build it my way"... Kudo's on an excellent kit for the do-it-yourselfer!

    very easy to assemble, well labelled and packaged kit.the kit comes to you fully labeled in bags with quantities and part number, which combined with following online tutorials make it very easy to assemble,
    just allow yourself 2-3 hours and a cup of coffee. and you should have a fully working MS3 by the end of it. here are some pictures for inspiration.

    brilliant bit of kit, great support.after getting an MS2 from here for my mk1 miata.
    and assembling it, along the process i learned a lot of things, and make a few mistakes, Matt from diyautotune was an absolute champ, and answered all of my queries and helped me solve the problems. gave me voltages and instructions to trouble shoot the issue (which turned out to be my coilpack wiring and not the ms2) :P
    later i built the sequential spark and fuel circuits along with switchable maps etc.
    it was a great learning curve and i quite enjoyed it.
    later i swapped my engine for a v6 KLDE, hence i got a MS3 to be able to have fully sequential spark and fuel for a 6 cylinder.
    having a ms3x card made the process piss easy.

    Would highly recommend it to any and everyone, its very easy to assemble as long as you have the basic electrical knowledge and a decent soldering iron.
    there is all the support out there for v3 boards. and diyautotune has incredible after sale support, probably the best in the business.,

    My truck has been up and running on a MS3X system 6 months now. I bought the unassembled kit and put it together with no issues other than my eyes not being as good as they used to be - I had to buy a lighted magnifier to do the soldering. The kit is very well marked and documented and well worth the effort.

    even thow I’ve been a real pain in communications, Matt and DIY Autotune were great in answering and helping in getting the package delivered in time for further shipping to NL,
    now to get it in my hands and put it together, can’t wait to start using my crabs as a doorstop…..

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
    • Stepper fast idle valve
    • 2 injector output channels
    • Tach input – Hall effect, optical, or VR sensors supported
    • Single direct coil control spark output
    • Onboard data logging
  • Adding an MS3X expansion card will add sequential injection, eight logic level spark outputs, and more.

I’ve seen a mention of an MS3 Daughter Card. Do I need to order that separately?

  • No. The MS3 daughter card is included as part of this kit.

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.

What firmware does it have?

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

    This includes the case and everything for the main board including jumper wires. Other add on boards that you can use with the MS3, such as the MS3X expansion board, knock module, and real time clock module, are sold separately.

    Most components have a -40 to +85 degrees C rating at a minimum - the main exceptions are SD cards and, if you're using a real time clock module, the battery for the clock module. But the SD card and real time clock are not "mission critical", if you're entering a Siberian rally.

    You'll need to Locktite all internal fasteners to avoid vibration, and clamp the wiring harnesses to the body about 15 cm from the backshell exit.

    If this is something like a trophy truck or similarly extreme use, consider an MS3Pro EVO.

    Somewhere in the trashcan of MegaSquirt history. An early bill of materials for the V3.0 board used a different part for Q16 which required a pull-down resistor on its input pin. The VB921 that was originally used for Q16 in early production V3.0s, and the later BIP373, do not require this. Consequently, no standard build guide or bill of materials for the V3.0 board has ever called for anything in the R57 slot.

    MS3 solves this problem by using six individual spark outputs and skipping the two EDIS modules.

    Yes, the MS3 can run this engine - including VANOS with the right mods. You will need to convert to a cable operated throttle body, and if using the BMW coils, you'll need a pair of QuadSpark ignition modules.

    TunerStudio Lite is a free download, available at this link. You can purchase the registered version from the TunerStudio site at the "Register Online Now" page. Currently, only ECUs in the MS3Pro family (MS3Pro EVO, MS3Pro Ultimate, and MS3Pro PNP) include the registered version; for all other ECUs, this is sold separately.

    Yes. It would communicate with the MicroSquirt over the CAN bus. You just need to run two wires during assembly to bring the CAN connection to the DB37 connector.

    You will need to add the MS3 knock module kit to best make use of a knock sensor, and I would also recommend the MS3X expansion board. The MS3 also supports vehicle speed sensor input.

    We include a solder cup DB37. The RS232 and USB cables are sold separately - as an off the shelf cable is fine for the communication side of things, we don't sell solder cup DB9 or USB connectors.
