    Turbo M50 ECU

    Hi guys,
    Just bought an m50b25 that I'm going to put in my e30, and will turbo down the line. I have the ecu and harness from the e34 that it came out of. Will a reflash of that work for a modest turbo or should I invest in a standalone now? If so which one does everyone recommend?

    Thanks in advance

    bosch ecu for m50 isnt flashable, only chip tuning. Not many people do those these days.
    Go standalone or convert to ms41.2 using the harness, sensors, ecu and trigger wheel from an m52 engined car.

    +1 for standalone, not too much more money new tech and flexibility.
