Did you ever get anywhere on this? I saw that there was an issue with it and an apparent fix. So I re downloaded it (thinking the newer one would solve the issue) with no luck. I'm having the same issue you are. Cant get my KR to log properly (among other things... apparently my WB doesn't want to either) so it is halting my progress.
Ive just been doing the ol look at WB, maf hz and KR all at once and making little adjustments here and there.
