    Pretty much as the title says..

    We have a 1987 pre-facelift E30 325i which has the Bosch Motronic 1.0 (35 pin connector) DME fitted to it. We're having a hard time finding a replacement ECU as the later Motronic ones were fitted with a 55 pin plug and the earlier ones with a 35 pin plug (which we need) and the first ones had the L-Jetronic which is of no use at all!

    We have found an ECU from an E28 525e which is the 2.7L variant of the M20 series so will it run the E30 325i?


    Any help is greatly appreciated!

    What's the part number of the ECU?
    It should run it no problem, so try it and see how you get on, but the 525e was never designed with power in mind.

    Unfortunately it's for a rally car so it wasn't of any use :( It would have fitted and worked but we found out that the 525e is mapped for economy with roughly 135bhp and a rev limit of <4500rpm haha!
