Great effort.

It will be cool when you will be able to see what CIS is really doing!

Larry at CIS Flowtech mentioned System Pressure drops significantly when the FD is working at higher flows. Might be interesting if you could monitor that to, at some point.

If this is true, looking at the fuel pumps might help gross delivery and or take some of the leanness off the upper RPM area. It would be interesting if we found it was the drop in System Pressure at high rpm that makes for the AFR's getting progressively leaner instead of the metering plate starting to slow or stall.

Fun stuff and good luck with it. Guesses are fun but real info rules.

The best.
