Can a coil make such a difference?
Discussion
Hello guys, I don't venture much into here so excuse my ignorance as an amateur spanner weilder.
I have a 1992 precat Griffith 4.3
So fairly standard RV8 apart from the internals of the engine.
This weekend I cleaned the stepper motor after the drop in revs was a bit sluggish.
After this I noticed the revs are dropping but the rev counter is telling me the revs are still 2000rpm.
As advised on another thread, the problem may be the coil.
So tonight I changed the coil with a known good one from a mates Chimaera 400
But with his coil connected the car revved to 2500rpm and wouldn't settle down. I started and stopped the car a few times and it did the same every time.
I put my Intermotor coil back on and the car is back to normal. It revs to about 2000rpm, then drops in 3 steps as the stepper motor does its stuff. And the rev counter is still indicating 2000rpm
Its confused me because I didn't think there were differences in coils. Especially as his is a generic painted black job. ie. nothing whizzy.
I'll now keep my coil and swap the king lead to see if this is causing the rev counter to go wappy.

There are different types of coil. One for ballasted systems and one for non-ballast.
However, both your car and the chim are non-ballast, or at least they should be,
, so that can't be the problem.
Not sure of where the feed for the rev counter comes from on the RV8, but on our crossflow, the rev counter gets its feed from pulses from the coil, I think its on the negative side of the coil (I think, not 100% sure).
Probably not much help, but, every little helps,
