    Hi everybody

    Sorry for this new topic, but i cant find a solution for my problem on the net, and i hope you can help for me.

    So this is the situation:

    i have a BMW E36 limusine 91' wih M40 with no abs/asr.
    3 months ago i have changed the motor, well now there is an M44 in my car.
    I have carsoft, and carsoft read a few dme fault codes, but i solved them exept one: road speed error.

    I read a lot, and i found that the dme waiting speed signal from the abs/asc, and now the max rpm is about ~ 5000.
    If i clear the fault code, the motor is good for about 5 minutes, and then the fault will come back.

    what can i do to solve this?

    thx for the answers

    You have two choices, either fit ABS into your car, or get the ECU tuned to remove the error.

    and how can i tune the ECU exactly? now it is a bit chinese for me but i am informatics, so i hope i can do if somebody give me instructions.

    thx again

    edit1: hmm i read a bit.. and ecu tune = chip tuning? sorry for my english, but sometimes something is not always clear. So this is the next question... if i take a chip tuning (ecu tune) in my car everthing will be ok? or is it some speciel tune?

    Yes, it is chiptuning.
    It will need to be something special but it will fix your problem.

    Ask around and see if you can find anyone in Hungary who can work with your ECU.
    Try these guys-
    Chiptuning | MMC Autochip | Chip tuning, tuningbox test
    They have a nice, honest site, and I'm fairly sure I have seen the name around before.
    If they are unsure of what to do, ask them to contact me

    If all else fails, you can sent the ECU to me (UK) and I will be able to remove the limiter for you.

    Hi guys,

    I've similar issue, but without any limiter problem.

    My engine is swapped, from M43 to M44, and I don't have ASC unit in my car. Therefore my ECU always get error "120 Vehicle speed (Signal wheel sensor) " I've tried to wire it differently, but nothing helped. If wired the rear right sensor directly for the ecu X20 pin 9, the ABS stopped working.
    I've heard that the ECU needs conditioned speed signal, does anybody know something about this? Additionally my car has automatic gearshift, and the speed signal is really important for the ecu.

    Anybody has any idea, how to solve this issue? I dont want to modify ECU.

    Many Thanks
    Zoltan
