Scott,

Sorry mate, said I wasn't all that clued up on cozzy management.
It is the sensor that picks up the disc at the back of the cam pulley that he had problems with.

Perhaps its time to get it on the back of a trailer and get someone to look at it.
You could be driving it in only a couple of weeks!!!!

Matt.

P.S. Was just reading back through.
You say you have a moded Dizzy that has the phase sensor turned round due to the cam direction being opposite from cozzy to RS Turbo.
Have you checked this is set in the correct position?
Does it generate the correct signals (if any) at the correct time?
