Are there any thumb rules that one should consider when making
a spark table for different cam.
There are a lot of tuners that make mail order tunes. How can they
make a good tune without having engine near them?
They usually ask for cam specs and from that parameters they are
able to make at least start-up maps.
In my situation, I'm about to step up from #219 cam to CompCams
HR-288-10 cam which has much more duration and even tighter lobe
separation angle.
I had custom tune from PCMforless for my last combo, but now I'd like
to try to do my own tune. I allready have WBO2 (LM-1), so I can
check fuel tune, bur I'm really concerned about spark tune.
Any information about spark tuning would be appreciated!
