Found this useful article on the Ginetta website which shares its ignition system with the MGRV8.

The Electronic Ignition system used on the Rover V8 is a basic system using mostly parts from much older generation of cars, with the exception of the electronic switching system used to drive the coil. It only uses a single coil that has to provide a reliable spark up to say 6200 rpm, so its worth taking a look at how this trigger system works, in combination with the coil and HT leads.
