Probably too early to give you that.
(Used 8.10 and PICkit2).
Ran for the first time today (no prop).
Over speeding not an issue. Ran like a Harley :(
No sure if because no prop or because not tuned yet or if
something else wrong.
Zero RPM readout on EM3. I must have misunderstood the
instructions or the program. I thought the EM3 got RPM from the
EC3, so I didn't wire the tach input to the EM3.
EM3 shows "NOP" until EC3 is turned on. Then shows "0".
Only did a couple of runs. Fuel pumps started leaking badly around
O-rings when I adjusted fuel pressure up to 37psi (engine not
running). Pooled up in fuselage. Need to fix before I try running
again. Gas is cheap, but not that cheap. I'll try copper washers
on the pressure (output) side instead of the o-rings.
Yes, I know, not pretty. Threaded the output fitting at an angle
:(
Too lazy to redo the output block.
I also need to bend a new input tube without a kink.
Max oil pressure only about 50 psi, hopefully because of low RPM.
Forgot to turn on master switch so alternator didn't come on-line.
Didn't log the run where that worked.
Anyhow, can now say I've run the engine :)

Great work Finn
Could I get the MPLABs version your using and any more info for the build.
I could build and program and confirm the burn but the EC3 ran like a dog.

Well, after several hours of Murphy working overtime, I finally was able to get the wiring on my EC3 chip programming board right, chips programmed and EC3 installed.
Flux capacitor fluxing, injectors clicking and spark plug firing.
Time to get the wheels on and roll it out and start the engine.
Oh, wait, guess I need to finish and install the prop :(

1) Without prop any vibration will be from engine and PSRU and can inspect engine (leaks, etc.) with no fear of prop.
2) With prop less chance of over rev and some cooling air through rads and oil cooler.
What do you think?
