  • How to: Megasquirt2 v3.0 and Megatune


    Installation
    The megasquirt is now ready to install.

    Cam Position Sensor signal - Pin3
    Cam Position Sensor ground - Pin1
    Crank Position Sensor signal - Pin24
    Crank Position Sensor ground - Pin1
    SparkA 1/4 - Pin36
    SparkB 2/5 - Pin4
    SparkC 3/6 - Pin5
    All coils ground - Pin2
    12V should be taken from the engine harness. Typically, you can use the pink/bl wire in a GM vehicle or the same 12V source the Megasquirt uses that doesn't switch off during crank.
    The following diagrams are of the stock 3500 ignition system:

    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...

  • 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...
