Well, I had purchased the PICKit 3 and finally downloaded MPLAB 8.15.
Unfortunately the PICKit 3 is not a programmer option in MPLABS 8.15.

Did you you run into this and solve it?

I could:
1) Keep downloading and install more and more recent versions of MPLAB 
until PICKit3 appears as a programmer option (and hope that the version 
still works with Tracy's code)
or
2) Purchase a PICKit2

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 to start on mags?)
