Car is a small block swapped ex-3.4L. My rpm's are way off. Theyre almost double my actual rpms. The car used to be a 6 cyl which might have something to do with it. I swapped to z28 gauges and its still the same. Is there some kind of translater of some sort between the coil and the gauges that uses the pulses and determines an rpm? Thanks all.
