Paul, Check this attachment.  Notice the items listed under the
 Time Distance Graph on the right hand side of the chart. Try right
 clicking on the lambda reference for setting the range.  You will
 probably have to save the reference some way.  Try file/save as/
 TTC2 or some other name.

 Things to note when interpreting his data. 1 -  His lambda
 reference is not displaying but it is recording, but note his range
 setting. 2 - His inlet air temp goes down in boost from the
 water/meth sprayed into the manifold. 3 - It appears that he
 short-shifted the first four gear and then made a pull in fifth.

 Thanks Barry. That really was a great help. I reset the ranges.
 That made a world of difference. If you were out here we would hire
 you.

 Hear are all five runs we did on 6-30-16

 Note run 1 with the small prop 30% throttle 7,000 RPM at 25.6
 inches of Hg!!!! The small prop was about 68 inches in diameter
 with a 50 pitch. About what you would get with a P-port normally
 aspirated 2 rotor.  ROFL We could probably could turn 9000 RPM with
 that prop at WOT

 When the RPM is over 5000 it was the small prop. 5000 below the big
 prop 84 inches dia. and 66 pitch.

 I think we put the big prop on about run 3 or 4.

 Obviously the waste gate control ( Aux3) was off on some of the
 runs. The weak spring in the waste gate was the only control I
 suspect.

 A really  funny thing happened. Some of the people were standing
 way in back of the airplane and off to the side about 100 feet away
 expecting the engine to blow in the piston engine hand grenade
 mode. ROFL I was wondering why they were doing that at the
 time.They know who they are:-) The noise at 7000 RPM was a bit loud
 to say the least. The video does not do it justice.

 I wonder what they would do at a drag race when the rotary turns
 11,000 RPM? Still ROFL

 Paul, happy Independence Day! I really wish I could be out there
 helping you for free. You help others for free... that way we just
 pass our knowledge on.

Are you guys using methanol as your main fuel? Are you also running
 water/meth injection to help cool the engine and stabilize
 combustion?

 Also what is the highest boost that you expect to run? I asked this
 because that's how high we would set the manifold pressure range.
 Let's say 20 to 110 in hg. For 40 pounds of boost. It doesn't look
 like you could achieve that high boost with the orifice being used.

 It looks like you have to fix the oil pressure signal going to the
 computer.

 I would set the lambda scale from .5 to 1.2 for better clarity.

 I would set the air /water/ and oil temperature ranges from 100 to
 200° F.

 Is the Moteck self learning the AFR? It appears to be. But when it
 goes back to idle on the ground it's to lean. Too close to stoich .

Yep Methanol with Castro oil. That is the only oil that mixes with Methanol.

240 KPa boost at 8000 RPM.
Here is a conversion table I wrote in BASIC.
240 KPa is 71 inches of Hg.

Yes on water injection.

Thanks Barry.
