Based on a fuel map inside the main ECU chip, the system could then control the correct fuelling right across the engine rpm, load and temperature range. The following list shows which ECUs were fitted to which vehicles: Main article: ECU Pinouts. The ECU for each engine management system is differentiated by the size of its plug.

When things start going wrong, it's essential to check that signals are getting to or coming from the ECU, and that means testing the wiring. To help you identify what goes where, here are the pinouts for each generation of E30 ECU.

2012年10月27日 · Where and how to access ECU: I have tried to illustrate where and how to access the ECU, it is in the glove box compartment. To access it open your glove box and undo the two screws holding the plastic cover that is at the “ceiling” of the glove box compartment, under there you will find the ECU and the Connector.
