that may be the easiest way, but it's certainly not the only way, or probably the cheaper way.
all you need is another amp (or replace the single one with a twin) to run in wasted spark mode (i.e. 2 plugs get a spark at the same time, but only one cylinder is ready for firing). you then need some way for the pulse from the ecu to the original amp to be split into 2 and sent to the correct amp for firing of the right pair of cylinders. this can be done with a microcontroller sensing the pulses from both the crank position sensor ad the phase sensor, but they need somesignal conditioning first.
ok so you can still tell me you dont need P8 to run coilpack on weber -
i didnt think so , all youve done is list a possibility what a crock , if its that easy why dont you build the unit your on a bout and sell it ?
like i said m8 to run it with no probs you will need the coil pack adapter that stu is trying to sort ( would be good if it happens _ havnt read the post yet
) but it can be done with P8 with just a chip mod and a bit of wiring and another amp ( or a dual amp) . the only problem you will have using P8 is driving the rev counter as stu says
i know all this because we ( me and MSD) looked into all the possibilities last year , and found that the best most reliable was to use the factory system !!
