Motronic55 to BMW e30 with m20b25

(1/1)

Tzl:
Hi!
I would like to replace the ECU in my BMW e30 to Vems Motronic55. Sorry for the amateur questions, but this is my first job of its kind.
My question is, this ECU pinout is 100% compatible with the stock ECU?
It can manage the extra things in addition to general things? I mean:
- outputs:  fuel pump relay, the main relay, the O2 sensor relay, the idle controller coils, the evaporator canister valve, tacho and econometer output for the cluster, MIL lamp,
- Inputs: A/C signals, throttle endswitch, Cylinder ID sensor, anti-theft input?
And in this ECU I/O points are configured to the corresponding type, direction and power?

Thank you.

https://www.pnpecu.com/ makes a pnp setup for this. Although you may need to switch some wires around in your x20 connector to get body related stuff working.
