    Help!problem with ms45 in a e30 m54 2,5

    Hey guys, I use the translator so sorry if there are some wrong words.
    I really need some advice and help now on my e30.
    I've read through all the threads on the forum but I have not found all the answers.
    I've done a motor swap and put an M54 2.5L in my 87 e30.
    But! engine runs fine all the way up to 4000 rpm and then it goes in limpmode, we have tried and engage the speed signal both cluster basis and directly from diff but no luck.
    The car is now with a friend of mine who is very good with ecu etc,, but he asks me if I can find more info on what to disable etc
    I run with MS45 and ews system from one Z4 car.
    So guys is there anyone willing and share info to me so I get the car ready for racing in Sept.
    I live in Norway, so there is a time difference of about 7-9 hours

      I run MS45.1 on my E30. Speed signal from the E30 cluster will not work, DME has to be reflashed to accept different speed signal. What other factory codes are you getting?
