Mike - Does your motec system give the 5V signal - I guess I would have to assume that it does? Do you have the part numbers for the coils? How did you source them?

That's surprising that noise was an issue. A Cayenne itself must be a noisy environment anyway with all the on board Latte machines and foot massagers.
Are you sure about the input signal you're giving it?
Motec has one I donated and they were impressed with it aside from intentionally shutting down at exactly 20ms. I don't think they supply it a 5v signal but rather a ground signal. It will probably fire with nearly any kind of activity. I'm over my head about that, it would be nice to hear from a boffin like Alan. I have a hunch you should not see the problems you saw and it's related to your wiring.
