Mathematically, for a 1 cylinder engine, the software should be able to
cope up to 30000 RPM. I have tried this on the bench but not in real
life. As mentioned though, it will be a little jerky at the top end.

Still, it was never meant to be a high performance product, but it has
been and still is a popular little project for people with older
vehicles.

What I found most interesting, is that although the electronic design is
very simple, there have been no operating problems that I am aware of.
Even the WDT is disabled. Only occasionally, an installation will run
erratic due to noise on the sensor wiring, but clears up after they have
been sensibly placed.

As soon as the newer flash based PIC's are easily available, I'll
probably have a go at a better design as I've got plenty of feedback to
sift through. There's only so much you can fit in the ol '84, and
believe me, each chip I program with this code needs the casing
reinforced to keep it all in :-)
