this is really a minor issue as it's not causing you any lost time on the track, but I'm curious now hehe
sorry, I ment later in the run. but still right after you hit full throttle. i did notice that with no timing advance set in the speedo, i never see this strange dip
i think it is a minor issue. I have seen it since i posted about using the sentry. so I have noticed it in many logs for like 3+ months now. what was concerning me was more in 13.5 the dip is almost 4000rpm. that I would think is pretty noticable on the track. and may almost feel like the motor was bogging down. so people without a data logger might think this feeling was over gearing. which from all my testing is not the case.
and I do not like the wide range rpm setting. i feel that it makes the motor feel soft and just add alot of heat. when ever I run the wide band the motor is usually 10-15 degrees hotter then with the narrow band. but the wide band seams to be more forgiving on gearing. the narrow band, I have found 1 tooth to make .2 a difference on the track.
