How can a fuel cut cause detonation when there is no fuel to detonate or pre-ignite?
Well, I have no real proof, but I'm guessing that it's possible for the ECU to see the rpm needed to initiate the cut as it is spraying the injector, and end up shutting off the injector mid-fire. Granted, I can't speak from first hand experience, but I believe it's the main reason most forced induction setups with standalones use ignition cut to rev limit, not fuel cut.
