  • How to: Megasquirt2 v3.0 and Megatune

    Planning
    First step is to plan and buy your Megasquirt. I used a v3.0 board and a MS2 processor. http://www.diyautotune.com
    Currently, the latest board release is v3.57 and processor is MS3. However, you do not need a v3.57 board to install a MS3 processor. It will work for either board version.

    I recommend a V3.0 board because it currently has the best documentation. However, the 3.57 board is pre-assembled if you are not handy with a soldering iron. If you choose a 3.57 board, you need to know this information to use this write-up.


    $430 Includes MS2 processor


    $253 not including processor.

    Processor choice is completely up to you.
    The MS2 processor has the best documentation and is easy to set up and use. However, it only has a limited number of inputs and outputs and cannot handle advanced engine operations like sequential fuel injection.

    $96

    The MS3 processor is very new and much more advanced. It is highly expandable and is for a true enthusiast.

    $199 This article however, only covers the MS2 processor.

    You can optionally buy the Megastim. The stimulator acts as a 'digital car' and is used for assembly/testing/flashing purposes. I highly recommend you buy/build one. It can be good practice if you haven't used a soldering iron in a while.

    $45

  • Heated O2 Sensor Install
    by bszopi
    This is a how-to on installing a heated oxygen sensor into your car. The benefit of a heated oxygen sensor is that your car will go into closed loop much quicker, which means the ECM is adjusting your fuel based off of the sensor and not maps. By doing this your car will run better quicker on cold start-ups. It will also improved fuel consumption during start up, as well as reduce emissions.
    First, you will need to get a 4-wire heated O2 sensor with the pig-tail.

  • EEPROM Code
    by bszopi
    Code is a language that computers or simple electronics understand, it serves as an instruction set to check what sensors are doing, and tells other electronic devices of the motor what to do and how to do it. For example, fueling and spark. "Code" what we refer to when tuning our ECU's, can be compared to as an ISO that is burnt to a CD. Or if you are not computer savvy, can be thought of, written letters and sentences on a piece of paper. The paper being the EEPROM and your writing as the code...
