I fitted my wasted spark kit to my 3 door today, fired up first time and what I don't understand is the rev counter is working and appears to be reading right and I have changed nothing on the clocks, I was expecting to have to mess with diodes but I was taken aback when it just worked, is this a fluke or has anyone else had such good fortune. I have a set of denso plugs as well but not fitted yet, what should they be gapped at for 1.7 bar of boost on wasted spark setup.
