Hi Mister E thanks for the reply.What I want to so is I have a hall sensor to sense input pulses.I set the static timint at 30 dgrees.What I need the PIC to do is at start up and idle delay enough to make the sparkplug fire at 4 degrees. as the RPM increases reduce the delay in proportion to the RPM until 7500 and above.Then have no dalay .To make the plug fire at all It takes a low pulse. Thanks for the help.Have a great day
BTW: the engine this setup is on is a converted weedwacker I converted it to a model airplane engine.
