Even the fastest race engines are going very very slowly in terms of computing power .

Neil.
~30MHz controller(if it's ~1 instruction per clock)?

I was under the assumption that calculating RPM is the most time consuming part, but when I really think about it, the frequency from the crank/cam sensor can be calculated very quickly.

Neil, I imagine your system needs to be "tuned" for different gearboxes, correct?
