It can all be done with one sensor, and no cam or crank sensors are needed.

The knocking cylinder is the one that just fired. Software keeps track of it, and retards THAT cylinder next time it comes up on its compression stroke.

Coil on plug is not a requirement. It can all be done through the distributor.

Couple of posts from a 928 guy with one:
That was both shockingly intuitive and in retrospect, obvious. Thanks!
