1987 BMW 535i
If this is an actual 535i (which it appears to be) it has the 3.4 M30. That was the most powerful, most desirable motor BMW put in these cars (besides the M5).
I'm amazed this thread is still up here. I actually just finished installing megasquirt onto the car. I used the innovative LC-1 wideband kit, put the A/F ratio gauge on a cheap pod on the dash. Here are some pics.

3" afm delete pipe with gm IAT sensor.

In the progress

Getting there.

Megasquirt to stock ecu, so I could use the factory harness.

Put in a new dash while I was at it.
