Hi Ryan,

Well What I am trying to do is make a autoadvance for small gas engines. Like model airplane engines. Most of the Cd ignitions you get for model airplane use has this autoadvance built in and one company who is no longer in business used to sell cd ignition kits and autoadvance seperate. Well I have been in contact with this person and have manage to buy some CD HV boards and a few of the auto advance boards. I am not wanting to reproduce the autoadvance to resell I just want to make one just for the heck of it. Now the ones I have bought use a 12F pic. A 12F629 to be exact. And one version the latest uses a 16C54. Looking at the datasheet for the 16C54 there is only one 8 bit timer. So I don't know how it is done. Any ideas is appreciated. I was thinking of using a 18F1220 and 2 16 bit timers. One to measure RPM and one to create a delay for the spark curve.
any ideas are appreciated.

Just guessing, but you could use a single timer for both generating the output and measuring RPM... you'd just have to do everything "by hand" and use the timer purely as a timebase for counting.

I would think an 18F1220 would make life a lot easier, even without the extra timers.

Are you thinking of using one of the existing boards or rolling your own?
