So.... I have solved my low RPM stuttering, juddering, hesitant behavior.
I have had a Power Commander V, AutoTune 200 and Factor O2s sensor eliminator fitted for quite a while now to my 2012 Versys ABS with Cat exhaust.
Other mods I have fitted are an Leo Vince Underbody SBK exhaust and also a BMC Sports Filter.
I've been sick with the flu for the last week and spent some time on Sunday surfing YouTube videos on How to use a Power Commander, How to reduce exhaust popping, How to use AutoTune etc.
You are not given any instructions or tutorials - and hence setting up with a DynoTune is recommended.
I came away with some helpful insight and information... Basically I need to be playing with the AFR settings! I came away with more of an understanding and now what I can do to.
So on Easter Monday after lunch I hooked up the laptop and started playing with the AutoTune AFR Map.
The default AFR map has Zero's in the low rpm and %throttle ranges... THIS is my problem. Zero AFR value means PCV must use PCV fuel tables (which are set to zero) so then factory fueling is used and hence my crazy jerky ride.
A Zero AFR setting meant that AutoTune was not ON at that part of the AFR map, and this means it was not changing any of the values in Trim Map which works on top of the loaded PCV Fuel Map.
I changed the default Zero values for low RPM (1250 to 3500) in the 2 and 5% throttle columns to have a values between 13.8 and 13.4 and blend in with the rest of the default AFR map (The bike was showing AFR's of about 14.0 normally so adding a bit of fuel with a richer AFR was OK). You can do this while the bike is running and see the changes instantly on the computer real time AFR readings. By setting back to zero you can see and hear how AFR readings were affected by the small cruising throttle changes.
I also the added a little fuel at 1250 and 1500 on 0% throttle to help stop exhaust popping.
Took it for a 1 hour ride on Sunday - absolutely changed the bike.
I wish I thought of doing this sooner.
Went to work yesterday and the bike is soooo buttery smooth in low RPM's
