just had a 325i conversion on my 318i cab, and had loads of problems with idleing etc, and the car kept revving up and down like it had a mind of its own, but sometimes was ok,
fitted the 173 ecu and put a new engine loom in yesturday night (thanks to dazleeds for the parts) and now she runs fantastic, carnt stop driving now!!

does the engine size and transmission affect the ecu numbers you have to use?
