Finally got my engine running right today, after checking compression,
spark on all plugs, re-checking for TDC (got an air hold- a spark plug
fitting and tube, put it into a bottle of water, and turned the engine
until the bubbles stopped and the water started going up the tube)
marked it and timed the engine for 22 BTDC @ 4000 RPM. Checked all
injectors for function.
Got Rich Martin to look over my shoulder and started tuning. Used auto
tune and found I was WAAAAAAY too rich. Adjusted the MAP table all the
way from lowest to highest MP.

It runs great now, might need some fine tuning, but I shouldn't be
pinching my seat cushion in flight.

Temps after extended running at 5000 RPM were oil- 148 [F], coolant 144 [F],
outside air temp around 46-50 [F]. Running at 2000 RPM the temps dropped
into the 120s. Will need some changes, but will wait until summer for those.
