Just a few technical questions to Tracy and  the group:

I have an EC2-A1T #274 upgrade 02-15-09

with EM2-B2 #166

While running today, I noticed that the address table would switch back and forth between #31 and 41, 42,& 43.

I checked the Mixture Correction Table Address Assignments (Pg 33 in the manual), and figured that was the jump off point to the 2500- to

3800 RPM part of the table.

So I ran the engine some more, and noticed that even lower RPMs with addresses in the 20's would jump up to 41, 42, 43, some times 44.

Then drop back to the original value (+-). Am I getting speed reference noise? The engine runs well, and smoothly, except when it jumps to

the 40's. During previous runs, Auto tune richened these up, and I smoothed it with the MAP table screen while shut down. That's another issue which I can handle.

Anyway, my injector wires are a few inches separate from the ignition wires to the coils. I have an RV-8, and the EC2 unit is mounted in the

right fwd baggage well. The  wires pass forward thru the firewall separately.

Also, I think I noticed some time delay or dead band when rising or dropping thru the 2500 RPM threshold. The Address number doesn't

change instantly with the RPM. Is that 'as intended'?

I ran briefly above 3800 RPM with no problems or changes required to the mixture control. So I don't have any obvious problems up there yet. The staging point occurs @ address 53, and is noticed as a small increase in power, but no change in mixture reading.

Exhaust temps are close, about 5 degrees difference @ 1500 F.

I started this run with a 'Test Card' to run in MAP table screen in Track Mode, and then move to Mode 8 Ignition timing.

This was good. I re-read the manual a lot before this run, it paid off. I ran the engine about 3000 RPM, and moved the timing to both limits a few times while observing the RPM and adjusting the mixture. I settled on the highest RPM, which is only 1 degree retarded from the baseline, using Tracy's initial installation instructions for installing the Crank Angle Sensor.

I have a Turbo engine, with opened rotor cooling jets and a restrictor in the oil fitting on the turbo. I get low oil pressure at 1500 RPM about 24 PSI using 5W-30 oil, about 68 PSI @ 3500RPM.

HOBBS= 3.8 Hrs. time to dump the break in oil and filter. I have a drum of Mobile DELVAC 1240 40W oil for Detroit Diesel 2 strokes, I think it would be safe in a rotary (both are ported engines)

I mix 2 cycle oil in the gas, about 75:1 for now.

My EAA chapter has member photo pages, and the web master recently cleaned up the spam, so I'm posting progress pic again.
