Note the FAQ at the end of this link. It says that the PV only holds one license, so you must use WinPV to load licenses you purchase for other bikes. Once you get the license code you apply it from Setup > Apply License, which I assume sends the license info to the PV for the ECM you want to tune. Therefore if you are on the road and want to tweak the tune of a bike not currently on the PV, but one you have a license for, you must bring a computer along to apply it using WinPV.
Whoever does this first should do a write-up here on the procedure.

Spreadsheet found: now a knock question.
I found ms 2010 starter on my pc. It's an interduction where they want u to purchase excel.....but it does open data log files. So the ms ***** are not soooo bad. NOT!
So in my data log I notice a consistent knock count of 5 in the front and 8 in the rear cyl for EVERY data point after the temp got up. Now the data point is a millisecond. How does it count 8 knock events in a millisecond? And how is it that it is ALWAYS 5 and 8 without exception?

PV Log File Storage
Does anyone know how much space is allocated on the PV for storing log files? Also, how does the PV deal with a situation where you are logging data and you fill it up - stop recording or start removing old log files?

I don't know the specific answer, but you should not have any worries. When I'm logging miles, the PV shows at the bottom of the screen the % space remaining (it alternates between showing the name of the log file and the % remaining). My last log run was the 5th I had on the PV, each log was about 30 minutes, so I had about 2-1/2 hours on it. It showed I still had over 90% remaining.

How accurate do you guys find the average MPG display with the PV? I set mine up and it's reading 51 mpg. Seems a bit high to me. Doing my own "at the pump" I was getting around 40 prior. Of course, it's hard to know if you fill the tank to the same level each time.

This is why I keep a small notepad on my bike - to record the current mileage and the amount of gas I put in.
This makes figuring out your MPG easy - and you don't have to worry about trying to put the same amount in each time.

Just go into the trip center and enter the miles traveled off the odometer and the actual gallons from the gas pump meter and you'll update the Trip Center with your bike's exact fuel economy.

"If we log ALL signals from the bike, that's about 100 bytes per frame. If we log at 60 frames per second, that's 6k per second. A minute would log 360K. An hour would log 21MB. So we could log 5-10 hours then depending on the number of channels logged.
The Power Vision will say, Error Writing to Log File Logging Stop if the memory limit is reached."
So with that, I'm guessing we must have about 128mb of storage to work with.

In the Trip Center click on the value itself, like where it shows Fuel Used and Distance Traveled, and it will give you a touch-pad to enter the values you actually realized. For example if it shows that you used 4.21 gal. of gas and you filled with 4.33 you would enter the latter value. From that it will calculate a correction factor that will keep it fairly close from then on. I don't change the MPG value, but rather only Fuel Used and Distance Traveled, which are the two parameters it uses to calculate MPG.

Like Heatwave said, you can make your gas-mileage calculations more accurate by using the Trip Center to change the Fuel Used and Distance Traveled parameters. It may take a few tankfuls but it'll zero-in on a reasonably accurate calculation in time. I find that my GPS, odometer, and Distance Traveled values vary somewhat, but I don't know why--and you'll never get the Fuel Used value perfect since you can't always fill the tank the same way every time. I wouldn't use the odometer to figure Distance Traveled, as it is usually not correct. Mine was 2% fast until I calibrated my speedometer, which was originally 4% fast, so now the odometer is 2% slow. That's okay since I'd rather have a correct speedometer than a spot-on odometer. I use the GPS for the correct distance per tankful, but like I said all of these values vary somewhat. I do assume the GPS is the most-accurate measurement of the three, however.

If you're going to use an odometer its best to use the bike's trip odometer combined with the gals used off the pump. This way you can enter very precise information into the PV and your fuel economy should become very accurate over time.
