hi all i am doing a project which consists of a 1990 mini, st170 engine, sierra gearbox, diff etc. i have got engine all in place with original inlet etc. now i need to get it running. i am going for the aftermarket ecu for tunability. i basically need to know how i get the variable valve timing to work. been looking at the megajolt system which runs with edis 4. anyone done this before or any ideas welcome. many thanks luke
