Distributor-less systems "Gems":

The latest generation of Rover V8 engines have no distributor at all, the system uses magnetic trigger from the flywheel and, with 8 separate coils, is the ultimate in spark management.

The 'Gems' type also uses the vehicle's own ECU to provide the perfect timing advance mapped to the engine's load and cruise driving requirements. Like re-mapping the fuel system, when you are in control of the spark management, some significant gains in engine efficiency & power will be attained.
