Best IAC Hardware to use?

[multiplex]

I've still been struggling to get the BMW IAC to work as well as I had hoped.

at this point, i'm open to other suggestions.

Has anyone found a simple two wire IAC, and have a good working config for it?

Thanks

Theres a part number and some settings - of course these will need tuning to suit your engine.
