Tuning Process
Thanks for the input. I have some great, very lightly travelled roads with decent hills around me that fit the bill. I'm going to bring my Netbook along and do a series of 30 minute rides, and stop along the way to blend the maps. PV is a great tool and will be more convenient to use than the TTS, which is also top notch. I may even extend out to 80-90 kpa and reduce timing, depending on how this all goes.

That is a very good process to cover more areas of the map. The tuning process for the PV and TTS is really the same. You cover as many areas of the map - combinations of RPM, load, etc as possible to make get the VEs as correct as possible. Nothing wrong with what you described - on a closed course of course

Let us know how the ride goes. The more you vary the RPM, TP, MAP and cover the different areas, the better the tune will be. Be safe.
Can someone of the more experience PV users do a small write up on using PV with Basic AT using the stock 02 sensors... I cannot go with the Wide band O2 sensors since my power duals have only 12mm bungs on them.... A write up from what to select on for the Log table on the PV to transfering the log from the PV to using the PV Log tuner software so i can optimize the VE tables for best bike performance or is should this be left for the Wide Band 02 sensors... II do think we can do Basic Auto tuning with the narrow band O2 sensors (stock)... I completed my Stage 1 and exhaust upgrade and uploaded the Map from my PV from FM.... i seem to be using way more fuel than when my bike was stock.. i estimate im getting about 60 miles less to a tank... wanted to ask here on forum b4 bugging Jamie.

A more comprehensive manual is reportedly forthcoming from DJ, but I don't know when it will be released. Maybe it would be good for someone with experience with it to go ahead and do a write-up, and when I eventually get to tuning with the Pro I'll probably attempt a write-up on it, probably co-written with someone who knows more than I do.

How do I lower the formula in the PV for calculating both Instant and Avg MPG that are shown in the PV's gauges?
Thanks for the guidance.

Iclick...can you walk through the steps for "correcting" the MPG calculations in the PV. After doing 1900 miles over 5 days last week (Laconia BikeWeek, NH, Canada, Me and VT), I've calculated that the PV is optimistic by about 10%.

>Select Program Vehicle
>Press "Accept" at the bottom of the page
>Scroll to the file you wish to modify and press Select
>Select Pro
>Scroll to the MPG Correction
At this point you should have determined if you need to add or subtract from the base value displayed in the box (e.g. "1989"). If you believe your MPG is being optimistic by 10%, then subtract 10% of the base value which in this case is 198.9 rounded up to 199. So 1989 - 199 = 1790.
> Select "Clear" and then enter the digits so the box reads 1790, then select "Save"
>Next you'll be asked if you wish to set the MPG adjustment to 1790, select "Yes"
> Lastly, the PV will ask if you like to save the changes, select yes.
*You can also modify the MPG by going into WinPV and opening your tune file. Expand the Fuel folder under Tune Items and select MPG Adjustment. Determine the correction you wish to apply and enter the value in the box. Save the file and upload the tune to your PV.

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.
