Here is a start that I created quickly using some of Jamie's posts, my notes and adding information I learned from tuning. This is a first pass and will gladly take suggestions and corrections. Let me know if this is helpful. I tuned first with the stock O2 sensors and am now using the Autotune Wideband sensors. I can add that to the instructions later unless DynoJet comes out with a better manual first. Iclick, we can collaborate on this if you like. If this is helpful, I can take input and create a more comprehensive manual if needed.

Thanks for the information. One question. After datalogging and developing a "new and improved" tune/calibration and downloading it to the ECM is this new tune then used as the base tune/calibration to make a new value file for future datalog/log tuning sessions? I assume that each time you datalog you would want to build on the most recent updated tune, not the base calibration that you started with. Am I correct? Thanks.

It's up to 860 now, and don't use 857 if you have it. I'm told it has a bug and was only out for a short time the other day.

Of course some of us are never satisfied and continue tweaking...

The problem with getting MPG just right is that it involves MPG Adjustment and VSS (Vehicle Speed), which is the Speedometer Calibration in WinPV. This adjusts the speedometer in the ECM, but this may be different than what you see on your fairing gauge. My ECM speedometer is 1.2% slower than my fairing speedometer, which I have set correctly and that's where it's going to stay. So, in my case I'll need to select between an accurate Fuel Used gauge or MPG gauges, and I'll take the first. I will be seeing a correct Fuel Used gauge, once it is tweaked, but my MPG will be off by 1.2% or thereabouts. I hope this is clear.
Edit: MPG Adjustment is now in WinPV too.

The MPG correction adjusts only the fuel-used parameter, and it is only available if you edit the parameters from within PV. You can get MPG and Fuel-Used both correct only if you mess with the Speedometer Calibration too, and since I have the latter set for a correct speedometer I'm only willing to use Fuel-Used. I am getting it tweaked, but the speedometer cal in the ECM is different from what is seen on the fairing gauge. So, when I get Fuel-Used correct my MPG will not be correct since I would have to throw my speedo a bit fast or slow, which I'm not willing to do. As it sits, I have Fuel Used about right and MPG is ~1.2% pessimistic, which is close enough.
Hope this isn't confusing. I just read it back and now I'm confused.

Ok now I am confused
. For me, the MPG is available in the PV and WinPV. I am using it to adjust my fuel ecomony (MPG) and it appears to be working. I am in the ball park and need to fine tune it.Am I misunderstanding something?

I see it both in PV and WinPV. It is only available in WinPV on calibrations created with the new revealed features OR You can "see" it on your current tune file by loading a copy of the current tune to the PV from the bike's ECM and then using WinPV to get tune from the PV. Once you do that you can save it to your PC and use that version to access the new features. You can use it to adjust MPG as you stated.

Dennis has it right. I can't see MPG Adj. in WinPV on older tunes, and the only way for me to see it there is to Load Copy of Tune from the PV and move it to WinPV. I can then edit, save, etc. and it'll be there in the future.
