Hi,
I installed a/c in my e30 318is. Everything works fine, but when A/C is turned on, rews drop low, that engine dies. When A/C is off car idle at aprox. 800 rews/min, when A/C is on drop on 500...I tried to connect signal wire from A/C to dme pin 85 or 86, but it is not better...
Any idea or sugestion what to do? I tried on both computers from e30 and from e36, on both same situation. Engine is e36 m42b18 with e30 intake manifold, engine wiring is from e36 engine.
Thx for help,regards, Dejan

The ICV is suppose to bump up the RPMs when the AC button is pressed.I would start with checking ICV.(ICV = idle control valve)

where you been able to sort the AC idle bump issue,
and why did you change intake manifold?
i did the same swap to an E30 316i, have to Say with DISA it does make a bit of a difference
