Out of a 90 535i automatic. Works perfectly fine. Has never been opened. This Is one of the ECU's that will work for your M30 swap if you are putting in the later e34 motronic 1.3 engine. Will plug right into the m20 Motronic 1.1-1.3 Harness also.
Just for shits and giggles I plugged it into my harness with the 2.7i and it ran fine. I didn't drive it much but it felt like the bottom end power was smoother.
This ecu is in perfect working order and has never been opened.
