    Part Number Revisions:
    Certain ECMs were re-released with different part numbers. There may or may not be slight changes
    in the internal parts, but they are interchangeable. They may even be just the numbers that are
    assigned if it is a re-manufactured ECU.

    Certain cars were set up to use ethanol/methanol/flex-fuel from the factory, as far as i can tell, the
    only models that had this option are 1991-1992 Luminas. They use a 16153084 ECM. It is
    externally identical to a 1227727. The known BCCs that use this are: AXAW, AXFX, AZRT, BAHA,

    • How to: Megasquirt2 v3.0 and Megatune
      by Jonpro03
      First step is to plan and buy your Megasquirt. I used a v3.0 board and a MS2 processor. 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...
