In the EFI world, if you want to control ignition timing from the ECU without even opening the hood or getting your hands dirty, you choose between a dual-sync distributor (for sequential port injection or CNP) or a crank signal-only distributor for TBI injection. Holley offers both dual-Sync distributors and the Hyperspark family of distributors.

 

If you don't want to use a distributor at all for Coil-Near-Plug, then you will need separate Cam and Crank sensors.
