Hi Finn I used the PICkit 3 for the EC2 code no problem (can’t remember the version of MPLABS) and thought the EC3 was more recent! Why did Tracy change chips?

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 to start on mags?) >>> >>> Finn >>> >>> On 6/16/2019 7:16 PM, Stephen Izett stephen.izett@gmail.com wrote: >>>> Hi Fin. >>>> >>>> No your right in relation to removing the chips and creating a programming socket.
