Yep as OG1 said, you can save the current flashed tune with the adjusted QT settings to a new tune slot, and it will carry with it the adjustments. i have an email from DJ stating this but have not tried it yet.

So I discovered something interesting today. I downloaded the PV Log tuner software from FM website (thank you for hosting that file!!).
Some of you may notice that after you load a PVV, and a log file, and then hit "Calc Tune" button, it gives an error the VE and AFR table is not loaded. This is because in PV2 the table names have been changed for VE and AFR. Log Tuner is looking for the old table names in it's code.
This is easy to fix.
Create your saved values file from WinPV with the pvv extension.
Open this file with "Notepad ++", a free structured language editor, it's like notepad but a heck of a lot better. free, no spyware etc. i use it alot for editing web pages and software code. http://notepad-plus-plus.org/download/v6.7.7.html
open the pvv in Notepad ++ and change the following table section titles, save file, then open it in Log Tuner and it will work for the tune calc!
Change "VE (TP-Based/Front Cyl)" to "VE (Front Cyl)" and "VE (TP-Based/Rear Cyl)" to "VE (Rear Cyl)"
Change "Air-Fuel Ratio (Lambda)" to "Air-Fuel Ratio (Stoich)"
Save. Changing these value titles in the pvv allows Log Tuner to now "See" it and load it correctly for tune calculating.
I still have to do some data logging per the Log Tuner guide, so I'll do that today as I'm interested in what it will show. There are no other graphical log analyzers for the PV2 data that I can find. I'm really surprised since just about all of the good automotive performance EFI tuners have log data analytic programs, graph plotting, etc. - Being able to analyze the log data in a useful format is quite important to improving tunes.

I spoke with Brian from FuelMoto. I asked where the sensor that provides HeadT (head temp) was located. He informed me there was no such sensor, this is a derived calculation. This nothing to be concerned with if high readings. ET is engine temp and is of more use to judge the temp at front head left side by cylinder.

My setup:
2015 Road Glide Special
Arlen Ness Inverted A/C
Vance and Hines True Dual headers
CFR Slip-ons
Powervision PV2
Using the canned map from Fuel Moto, the bike runs well. I am trying to dial it is with Auto Tune. The bike runs rough as hell in AT. In third gear, and especially 4th gear, power disappears, the engine lugs, then there is a loud detonation. This AT based on the preloaded Fuel Moto map for true duals and hi flow A/C.
I have read the the bike will often run round in AT, but when I export the map and load it, things are slightly better. There is less hesitation, but in fourth the engine winds out and there is that loud detonation and power picks back up.
Should I fight through it and keep running AT, or is this bad for the engine? Anyone else have similar issues with AT based on a known good map?
