I think mostly moved over to John's system with the 12F683 as this one still has the misfiring problem. As the source code has been withheld, it is difficult to say where the problem lies.
It would have been nice to see it completed as there are many great features and a LOT of work from Gompy and other people also.
For the time being however, it is a system you sit on the bench and watch all the pretty pictures but connect the ignition board and things go crazy. Spark is irratic and self-triggering, even to the point where it will wipe part of the program.
I know John tried many things and I also made a test board where certain parts could be isolated to try to narrow down the fault, but just when it looked promising, things would go belly-up again.
Might be usable in the future as an electronic injector for a diesel engine.
