Does anyone have a solution to this? My 20v 4AGE with LEM V5 is doing the same thing. The fuel cut/max rpm limit is coming on randomly (usually around 3-5000rpm) and the diagnostics say it has around 200 sync errors and max rpm of 25313rpm. While revving at idle everything is fine. Going up hills seemed to make it happen more often (I assume because of more load). It was running fine, then I changed to a more fuel economic map and then changed back to my original tune and then it started happening.
