Ok,

For the benefit of the origional topic poster, if you are running P8 then all you need is Stu and Kenny @ Motorsport Developments to sort the software out for you. If you are running an L8 then you will need the SECS driver board.

With the P8 you will need a dual or second ignition amp and a wiring harness to run the coils and amps. You will need a spare pin on the ECU to fire the second coil. The other thing required is a pulse amplifier to run your rev counter.
