stu at msd has done mine and its great. fires straight away and never misses a beat.
whats involved.
1.coilpack and loom
2.twin ignition amps
3.coilpack leads
4.coilpack driver in ecu
5.mod on back of rev counter.
stu supplies all the parts as a diy job. this is what i did but just got stu to put the driver into the ecu. the mod on the rev counter is really easy.
he does the whole job with full instructions as a diy kit for £400
