Truth in dyno
Just to clarify. Once the software is open and you're past the disclaimer, you'll need to click on the "Tuning Fork" icon on the top menu bar. Once you click on this icon a new window will open. There will be a white screen in the middle of this new window with 2 tabs above it. One tab will say "Stored Calibration". This tab is the default that the software opens to and generally points to wherever you have stored your various tuning maps.
Next to the "Stored Calibration" tab is is a second tab labeled "VCI". Click on this tab and you'll see a new field with a button at the bottom labeled "Load From VCI". If you're not hooked up to the VCI, the button will be grayed out but you can still see it.
If you're computer is hooked up to the VCI AND the bike AND the main ignition switch is "ON" AND the hand control switch is in the "ON" position, then the "Load From VCI" button will become activated.
At this point you can click the button and whatever map is currently stored on the VCI will be downloaded to your computer. Once you've opened the file you can save it to your computer using the "Save As" function. Once its saved to your computer you can modify the map, rename it or do anything you want. My recommendation is to save 2 copies. One that's untouched as a backup and the other to be modified as needed.
Essentially any map on the bike that has been saved to the VCI can be pulled off the VCI by anyone with a copy of the 2010 SEST software so long as they have the bike AND the VCI that is mated to that bike.
To download the file from the bike it's a simple matter of connecting the VCI to the bike. Have the software up and running. Turn the main ignition switch to "ON" and the right hand control switch to the "ON" position.
In the software, open the "tuning fork" tab. Then click the "VCI" tab. Then click "Load from VCI". The software will then download the current map that's on the VCI to your computer.
If this was a map created by a tuner or from any other source, you will now have the map downloaded to your computer. Once its been downloaded, you can "Save as" the map and store it as a duplicate to be modified however you wish or just to keep as a backup.
Unlike the SERT, the 2010 SEST absolutely allows you to download the existing map that's running on the bike so long as its still on the mated VCI. I've personally done it this week after my bike was tuned by the dealer.

I have seen many posters on here that attempt to tune there own bikes off of their dyno printout, It can't be done properly. Your printout is only showing 1 cylinder at full throttle, it might me totally different at other throttle positions, so if your printout shows your bike is running rich at 2500 RPM's and you decide to lean it out a little across the board, guess what? Your bike might of already been lean at cruising and you just leaned it out more.
Thanks for the info, I need to spread it now.

You can try 13.2 but on some of the higher compression builds you may see detonation at higher rpms if it is that lean. Removing timing when it needs more fuel makes for an unhappy motorcycle. Your graph lines will not be smooth.
My 13.2 to 1 dyno tune had my engine knocking like a wood pecker.
Ran great while they had the knock feature disabled on the dyno then they turned if on before they gave it back to me and it ran like crap. I wonder how much engine damage was done during the 60 miles of dyno tuning that day???
Both tuners that have touched my bike also tuned my engine with the wrong timing tables. You would think they know that a 260 HD cam has a .609 lift and use a base map that starts with timing tables available for that cam as well as what size TB & the cubic inch are you using!
I'd bet there are not 10 tuners across the states that know how to really tune a bike that has more than an a/c and small cams installed.
One tuner focuses on air to fuel and another on max hp & tq but none I have seen ask what compression are you running, do you ride two up, what kind of fuel do you use, did you change gearing, do you ride the freeway a lot, etc.
End of rant!
