recieved  the TTS a couple days ago and  loaded it on the puter..Was looking through it  a little  and ran across the part that mentioned the speed change. it said something about the   32 tooth trans sproket and 70 toothe rear pulley. My bike id did the clutch basket  ring gear change  also to a 49 tooth from the 46 to get me at the 3:15 gear.
Since then i took the device to my tuner, but i am wondering what to do to make the correction or the steps required. Thanks,
Happyman

If you change the primary gears, you need to correct the primary gear ratio. If you changed the secondary gears or tire size you need to correct the speedometer. So from what you said you changed the primary gears. Go to the ECM Tuning Constants and look to the right side of the screen and you will see a tab that says Primary Ratio and "click" on it. Now select the new ratio you have installed into your bike. That's all you need to do to correct it, then program the calibration into the bike.
The Best you know, is the Best you've had........ not necessarily the Best.
