    M4.4 Remapping.......

    This is how I went about flashing my 2.5 lpt M4.4 ECU

    Tried putting a battery charger on the battery to get the voltage up to 13.5v, the battery charger would only raise the voltage to 12.5v.
    Borrowed a charger/booster which raised the voltage to 13.1v



    On the Wiki site it states the voltage needs to be 13.5v but I`ve found that aslong as the voltage is greater than 13v it will flash the ECU.
    Using the software and bin file from the wiki site started flashing ECU




    The only change I`ve done to the bin file is to lower the tickover from 900-1000 rpm to 700 rpm.

    Before


    After


    This is the part of the bin file I`ve changed



    I`m not going to go to mad with this ECU until the forged engine is up and running................. then the fun begins

    A bit of careful testing, good idea to dip your toe and see what happens, think I'll be doing the same as my head is still hurting from a flashing overload from what I've read in the last few months, think it will be at least a year till I get going at it properly, but enjoying reading all your thread up dates Rob

    Been going through the bin files over the last few evenings and have found a "launch control" file

    Hope to copy this file over to the map that I flashed onto the ECU at the weekend

    Be interesting to see how that works, it must just limit the rpm while the car isn't moving

    As far as I can tell it works when the clutch is depressed, you just set the a max and min rpm.

    Also you have to set a restart rpm which I think is for when you lift the clutch for the engine to fire on all cylinders.

    It`s a shame it only works by stopping the injectors not the spark plugs

    So it'll only work on cars with cruise control as others don't have the clutch switch. The system I use cuts the ignition so sounds like the wrc cars anti-lag

    Think the launch control was changed because of the switch problem, the switch part was cut out of the code. Will have to check but I think the launch control applies when the car's speed is 0

    launch control is controlled via the speed sensor on the car, ..... you set the rpm etc and the speed before launch control releases.

    I cant run it on my build due to not having an abs/speed sensor.

    so I will be re editing my map to read a micro switch on the clutch

    I`ve been doing some more reading up on this and I was wrong, it doesn`t work off the clutch switch.
