Hey I have a question about tachs
I was wondering what the difference between the signal coming off an engine of 6 cylinders reads to that of a car like mine a 97 pontiac firefly, which only has 3 cylinders and runs off your basic distributor type ignition(if that is any help). Any of the tachs that i have looked at are for 4 cyl and up and I was wondering if there would be some chance of hooking one up in my car.
I have seen tachs for 2 cyl and up but they are amazingly expensive and come with ugly dumby lights. all i was is a basic 2 1/4 tach if you can give me some advice on this it would be awsome.
