My understanding of electronics is minimal, but I believe no matter what this RPM reading would have some jaggedness without filtering. Looking for an opinion on the RPM1 signal here to see if I need to figure out how to improve it. My only real other option would be tot mount the controller on the wall and not in a cabinet with the computer like I have it now.  Then the wire could be much shorter

 

I wonder here if the RPM signal is causing the brake to load more here or if the more load is causing the RPM  signal issue

Hi,

I don't think there is noise on the RPM signal here, but to be sure, post the raw .log file. 

I see the brake settings needs adjusting though. It will probably behave better with a "Ramp up brake" setting that matches the power of the engine (try ramping up to 40-45% starting 1000 RPM under the start RPM) and more Kp and possibly more Ki. 

I can help you tune in the brake if you are stuck.

what should the air gap be from the rpm sensor and the trigger wheel

About 1mm or 40 thousands of an inch is suitable.
