Hi Finn Sorry about the delay. I no longer have that pc, so cant confirm.

All I know is that Tracy said he could not get it to work with more recent version of MPLABS. I guess it was easier for him to revert to MPLABS 8.15 rather than figure out how to get it to work with newer version of MPLABS.

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.
