    L-Jetronic to Motronic 1.0?

    So we have a 323i e30 with a b27 swap and we found a motronic 1.0 ecu and engine harness from a e28 525e as we couldnt find a 325i engine loom and ecu as they're hard to find.

    The problem is that the fuse box connector is similar to the engine loom but smaller. How would we go about connecting these two up?

    Also is jetronic to motronic 1.0 possible on a e30? Since we got a loom from a 525e its a bit tricky getting everything to connect up

    Sure it's possible. Sounds like you'll need to convert or adapt the C101 fuse box connector.

      possible but wouldnt even bother ...

      just go for a megasquirt setup, at least you will get a modern ECU in exchange for all that work ...

        How would you go about doing that? I have searched everywhere and still have no idea.
