TTS V tune help
I installed the TTS on my 09 St.Bob this weekend - I wil admit I was a little apprehensive about the install but after a little reading and basicaly "diving in" - it went pretty well. I was able to save my factory map, install a "base" map and adjust the speedo for my 30T sprocket. The bike runs pretty well right off the bat (SE A/C and SE slip-ons) but it got dark and late before I was able to start my data collection runs for the V tune.
I have an okay laptop but I'm not to sure about my battery time. I tried to strap the laptop to my tank but that ain't happening - so I'm going to have to stash it in my saddle bag. I really want to get the most out of each test run. So, my question is for TTS owners - do you have any hints or suggestions for the V tune data collection rides ??? Should I just ride it like I normally would or should I be trying to go "red line" through the gears ???
This is where someones prior experience could really help me out - thanks.

Just ride it like you normally would,,,,When i did my first two runs i red lined and tried to hit every cell possible,,,but on my last run i just went on a normal ride and i got a better data run than the first two,,,With every data run and map flash your going notice a change in the power ,and sound and feel of your bike,,,

You will find that if you ride the bike like you normally would you will get relatively fewer cells populated i.e. not get a good set of data. This is because the TTS (and SEPST) ignores data for several seconds after a throttle change. So if you are riding around town and then perhaps at just your normal cruising speed on the highway you won't collect much data.
The minimum time you need keep a steady throttle opening is 5s and that's actually quite a long time when riding around town or in traffic. Its even better if you can leave the throttle at the same point for 10s to be sure to get a good reading.
Ideally you need to find yourself a really long, quiet stretch of road. Then ride at 5mph increments for 5-10s in 1st gear until you get to the red line then repeat in 2nd gear and so on. This might take several recording sessions. Once all that data has been merged in you can record a nice long normal riding session to fine-tune things.

I did everything I could think of to hit all those cells and never could get them all. I did 3 1-hour sessions and called it good for now. Still, 100% better tune than it was with the PC. I still have some stuff I want to do with the engine before I take the time to get a perfect tune.

Yup, I spent some time early on trying to fill in those elusive cells and then in a "Doh!" moment it occured to me that if I can't ride the bike to hit those cells then they don't need filling as I obviously just don't use the bike at those particular settings.

Thanks for the input. Unfortunately the weekend forcast calls for rain but at least the bike runs good with just the canned map. In the meantime I'll be looking for a quiet stretch of open road.

B.S,, Unless you know how he normally rides ,,,,I rode one 30 min run in my normal range and hit almost every cell,, but i do live in the country ,,I agree with with most of your facts,, but no need to get nerdy with the tuner ,,its just simple,,, just ride smooth and don't blimp the throttle ,,,

You do the best you can over three or four VTune rides. Hold the throttle as steady as you can. Some throw some masking tape on the throttle and mark of a few degree increments. In a few different gears go through the throttle, stopping at each mark for five or six seconds until you either hit the rev limiter or safe riding limit. If you have some hills, take advantage. If you have a willing passenger, take advantage (especially if you intend to ride two up). Don't take any chances with safety, its not going to make a difference. Finalize your tune, load it onto the bike, step away from the lap top (lock it away) and enjoy your ride.

I was lucky with my tunes. Took 4 different rides. Took 2 just 1 up and 2 2 up. While doing the 2up went on the parkway,good twisties and hills. I just rode my normal rides. I did noticed that every time that I v-tuned the bike seemed to perform better and my normal way of riding changed,seems the engine likes higher rpms before changing gears after each tune...lol
