Attached are the chip configuration settings. In MPLABS, pick the
settings listed on the right. Most are MPLABS defaults for the 18F452
chip, but a few need to be changed.

As for Sam's, Tracy did extensive modifications for Sam'scontroller= that
he now regrets having done. Sam would really, really be better off with a pair (for redundancy) of SpeedUino boards. Program them for a 4
cylinder Subaru and go from there. (What might be happening with the EC3 is that it has a startup timing setting and a running timing setting.
That big bore Continental may have one cylinder firing that swings the
prop around at a speed that fools the controller into thinking that the engine is running and switch to running (advanced) ignition; but the
engine didn't start and now the next spark comes too early. Why Sam didn't experience that until recently I don't know. Maybe he used t= o
start on mags?)
