so my friend went FI on his last 3 M3's and subsequently has extra ecu's turns out one of the cars that he bought had a dinan chip in so he swapped it out for a stock ecu. well i am buying the ECU from him and want to put it in. so today i go to his house and we put it in, but my car wont start, it partially turns over and then the dog gear pulls out and the starter just spins. my car has been doing this recently alot with my sock ecu. it would not start after 15 tries, so i put back in my oem and after 3 tries it came to life. now could this be because my starter is just bad and i know it is, or is it because the car doesnt recognize the ecu? i want to think that itwill work, but i hope i dont have to mess with the EWS or do i?

you have to have your ews aligned. this can only be done with a gt1 machine at the bmw dealership.

btw im assuming when you said the ecu has a "dinan chip" that its actually just dinan software downloaded on a 96+ ecu correct?

a 95 ecu that actually has a physical dinan chip will not work in an obd2 car.

You can disable the EWS by cutting a wire at the ECU (66 iirc). A quick search would give you the correct wire. Of course that is ghetto engineering, the correct fix would be getting the EWS aligned at the dealer. (if they would do it)

Your starter issues are completely irrelevant to the ECU and or the EWS.

No that doesn't work on an obd-2 car, you can't just cut the wire that only works with obd-1, you have to take it to the dealer to get it re-aligned

True. Ask me how I know...

My dealer only charged me like $65 to have it re-aligned. This IS an OBD2 ECU going into an OBD2 car, right?

Your starter issue sounds like it's totally unrelated...

Realign the w if u can find a dealer to do it. I was unable to find a dealer to the get job done so I missed a good deal on an AA ecu.

why did you have to capitalize dinan?
