Well, I installed my new prop today, hoping for higher rpm’s.  I mistakenly assumed that by installing a smaller diameter prop with less pitch, I would gain engine rpm’s.  Wrong.  I am still stuck at 4800 rpm’s, big prop or little prop.  I tried a high speed taxi (around 60 knots), but rpm’s didn’t seem to increase.  I decided to play with the mixture a little bit. With the MicroTech, I can either adjust the mixture for the whole power curve (idle up to WOT), or adjust by MAP settings, or by throttle position sensor position.  I decided to play with the map settings.  I was always rich at idle.  I went into the idle screen on the programmer and adjusted the idle for 15 and 20 map (leaned it) and it ran really smooth. I still am having trouble increasing the high rpm’s, however. The MicroTech is capable of so many things, that it is overwhelming (to me, at least) to try to figure what the he** they are referring to with injector millisencond adjustments, air fuel mixture adjustments, timing advance adjustments, and 14 other pages of crap (they call it useful information) that is to say the least, intimidating. I’m sure what I need is in the manual….just have to decipher it all.  Anyway, didn’t try to fly it since I was only getting the same old 4800 static rpm’s.  The good news is that after an hour of reading the manual, I was able to fine tune the idle mixture so that it had no effect on the rest of the throttle settings.  I guess I could say that some progress was made.  (Maybe 10 percent, only 90 percent to go).  Water and oil temperatures allowed me to run it long enough to try to tune it, do some high speed taxi tests, taxi back to the hangar and fiddle some more before shutting it down at a water temp of 210 degrees F.  I put a fan blowing up into the NACA duct and it cooled down relatively fast in parked in the hangar with the fan blowing into the NACA thru the radiator and oil cooler.  Hopefully, more fiddling tomorrow.  Paul Conner
