Getting Started with Master Tune
1) What's the best AFR Voltage to use when tuning...684,690, 700? or any other starting point that anyone has used and got a good tune with.
2) After the first 20-30 min. run and you have gather some calibration, do you use this same info to start the second 20-30 min.- run? If so how is it done. I guess what I'm asking is how do you perform the other needed runs?
3)Any help on how to blend the VE Rows would be helpful
4) Any other pointers or sugesstions to get a good tune would also be helpful

Anyhow, looks like your starting map would be UH205-002-c2.mt7 . If it is a 96, you will have to go to the tuning constants part of the map lower the 103 engine size down to a 96 if yours is a 96.
I have tried running at some different Closed Loop Bias voltages and found that 684 was a good medium voltage for MPG and 721 was a good voltage to run for slightly cooler and responsive feel. There is not much difference between the two and I favor the 721 a little more. I had my bike dynoed and the mapper used 781 on mine, but it will probably shorten the o2 sensor life some.
You don't blend the VE tables until you get to the final Vtune run. Then you take the last VE value learned and use that value to entend out to the end of the table. You do the rows first then what is left at the bottom of the columns, you extend down from there the learned values.
You can probably dial it in pretty good with about three vtune runs. Be sure to backup your stock original map before flashing the ECM with a tuning map. This is a one time save.
Once you've saved the original stock map, you call up the Mastertune map that you want and you set it up for collecting Vtune data. See user's guide. You make a run collecting Vtune data then you use Vtune to merge the data collected with the map you are tuning with to create a new map. You then flash the new map into the bike and go for another data collection run. Repeat this process until the cells are white or light pink.
When satisfied that you have done enough vtunes, and have a final map, change the map tables back that were manually edited by you to collect the data and save the new final map. Flash the bike and you are done.

The V Tune without a dyno is by DOC. Use this one for your initial set up which will produce the desired results. You can also pre read the Master Tune manual as well. Once you have it dialed in and are more confident working with the soft wear, you can further tweak it using the Master Tune guide. Have patience, Good Luck

That way, the map that you are tuning with needs less and less changes each time you flash the new map into the bike. Just remember when you are satisfied with the last vtune run, that you have to change the tables that were modified for collecting data.
