    Swapping to 1.3

    I have a 87 325ic I have been told I can just swap in a 173 ecu since I already have the I motor is this true? I think it has a 153 in there now

          A 173 or later DME will do a better job of idle speed regulation, supports the stomp test, and has better tuning chip availability.
          The car makes it possible, but the driver makes it happen.

              I did this with my 88ix that had the 153, it should make you your check engine light blink codes to you

                  I tried both a 173 and a 524 in my '87 sedan. Both of them smoothed out the idle and provided a smoother application of power. You can swap in any E30 ECU 173 and on and they will provide about the same results.
