Just realized that the Dynon system collects fault codes for the 912. Will check that in the morning for anything useful.

I don't have a dongle. I see there are three levels.
Clearly level 3 is out for me. But would it be better to get a level 1 or level 2?
Level #1 Allows you to read and view the Log files only. No Changes Allowed.
Level #2 Adds the capability to clear the faults in the ECU once you fix the problem. <---<<< This One! ***
Level #3 Allows you to change some operating parameters in the ECU. Limited availability.
There is a Level #4 Dongle that probably is only available to the design engineers in the factory. (The God Dongle!)
They are all physically identical.
Only the internal software is different. (And of course the Price!)

Well Paul, you have investigated fuel and air. All that's left is ignition. Your symptoms are similar to a magneto check - EGTs go up and RPMs go down. Maybe you are operating with only half ignition? Unfortunately probably not an easy fix on this engine.

Thanks Jon,
investigated fuel and air more today. Fuel is getting to the injector section with pressure. Cleaned the air filter just in case.
It could be ignition as anything is possible at this point, but it would seem like I would get a fault. The engine runs the same on A or B only. So if it is ignition it is affecting both lanes. From what I am hearing that is not likely with the redundancy in the engine.
With the redundancy in the engine it would seem that it would run fine and show a lane fault. Without the fault it points to something shared by both lanes, fuel or air.
Really frustrating....

Worth a try to check the fuse box, fuse box connections, and ignition coil connections?
