I'm running open loop on my 08 heritage, cruise range is set to 14.2 i tried a few other afr's this is where my bike felt the most responsive/smooth. I did,t notice any meadurable cooling benifit from this though, i'm sure there was some cooling but nothing to brag about. The biggest area i noticed as having a cooling effect was increasing the idle range to 13.8 afr.
As far as running open loop i'm not sure about TBW bikes but you do not need a PC inport, if you set AFR outside of 14.7 your ecm automatically goes to open loop. There is also a switch in winpv that turns closed loop off and on. Again i have a cable bike so i'm not sure about any tbw bikes but they should work the same.
In response to your previous question about importing you pc3 map and auto tuning your ve's it would kinda defeat the point of loading the pc3 map to begin with. I imagine your bike was overly rich with the pc3 so if you were to auto tune it and correct you ve's it would probably lean it out a bit. What kind of mpg's were you getting with the pc3? Did you ever look at the plugs while you were running the pc3? The only other thing i can think of as far as you getting higher temps would be if there are any major changes in the spark tables as this can effect temps.

I have an 07, and did have a PCIII. I realize I don't need a PCIII import map, I had one and kind of assumed it was an asset. But, maybe not.
I got fine gas mileage with stock FuelMoto PCIII tune. Almost always in the 39~41 range. So no complaints on that front, although I do ride conservatively, and usually as a tourer in the 2300-2800rpm range. So I'm not always hard on the throttle.
The plugs always were slightly dark in my opinion.. but never black or obviously overly rich.. they were just more charcoal than gray color. But, I was willing to live with that since the bike ran perfectly, no popping anyplace, and like I said, it ran usually in the range of 190'F-205'F except on the hottest days (90s) it might creep toward 215'F on my oil temp guage.
Here in New England hot weather doesn't happen all that often but prior to my PCIII stage 1 and the Jagg oil cooler the bike ran hot. The Stage 1 helped a lot and then the oil cooler just brought it down another 10'.
I'm working through the AutoTune basic process now and once I get that dialed in, I'll reassess my next steps. Given I love the bike and intend to keep it for a good long time, it's not that big a step to shell out the extra bucks for the pro kit sometime this season.

What are the actual changes?
I loaded the Fuel Moto map included with my P.V. for my setup and noticed quite a difference in pulling power. So next I started fooling around with autotune basic and began to save the new tunes and use those for the following auto tune runs. I looked at them in winpv and looked at the changes in VE comparing it to the FM original map. I see that fuel maps themselves don't change so what is the effect on my engine tuning ? I have done some logging and looked at that but I don't have any intelligent questions on that yet. It's been a late spring so my riding time has been really limited as well. Thanks for any replies.

If your fuel map is calling for say 13.8 AFR but your ECM doesn't know how much air is in the combustion chamber there is no way for it to deliver the proper amount of fuel. Once your VE's are set then whatever AFR you have in your fuel map will be what the bike is actually running. After you have the VE's dialed in you can then move on to playing with different AFR's and timing to see what your bike actually wants/ runs the best on.

I have just downloaded the latest update for my Power Vision PV1 (Firmware Version: 2.0.2-1233) and when I started to run an Auto Tune about half ways thru the first half of the complete program a new 'Pop Up Pane' appeared.
It stated something like: "If you want the unit to automatically Auto Tune" then it gave you an option of 'Yes' or 'No'. It highly recommended not to answer 'NO' if you don't know what your doing.
Can anyone explain all this to me, PV's website has nothing I can connect to this new Pop Up Panel.

I've never seen this happen, my bikes torn apart getting a 106 put in so I can't experiment with it. Keep us posted if you find out what's going on. What do you mean in the bolded statement above? Do you mean first half of the AT run?

When you autotune you are not changing your fuel map, you are changing your VE's if you go into that table on in WinPV and compare with your base map you will see where all the changes are. What happens when doing AT runs is the PV sets the whole fuel map to 14.7-1 AFR in order to utilize the O2 sensors, it also retards your timing by 4 deg. Doing this lets the PV get feedback across the board in order to make the changes to your VE's.
If your fuel map is calling for say 13.8 AFR but your ECM doesn't know how much air is in the combustion chamber there is no way for it to deliver the proper amount of fuel. Once your VE's are set then whatever AFR you have in your fuel map will be what the bike is actually running.

OK I have the VE's dialed in, saved and installed in ECM. How do I "move on to playing with different AFR's and timing to see what your bike actually wants/ runs the best on."

By the first half of the Auto Tune program I'm referring to the section where you load in all the parameters before you start the engine and ride the bike and beginning to start to fill all the cells with data.

I thought I read yesterday that it gave the user the option to just record the data without it actually affecting the tune. Kind of redundant to me. Of course I can't find where I read that. I decided not to download the latest firmware and software update.
I don't have the PV close by, but if you hook it up to your computer and use the Update Client, it might give the info as to what was updated.

Gotcha, I'll have to check my firmare and see if I'm running the same version as you. The last time I checked the update client was about two weeks ago so if the newer firmware is came out after that I don't have it yet. When I go to auto tune it doesn't have me set any parameters if I remember correctly, it just asks if I want basic or pro, has me select the tune I want to AT, loads it and then has me shut the bike off for 10 sec before restarting. After that I go back to the AT screen and hit datalog to start the AT session. Is there more steps in the new firmware?

Really for the AFR I just played with the cruise reange to see what my bike liked the most, I was happy with my lower RPM and higher RPM areas. tried 14.0 14.2 14.4 and ran closed loop with bias set a 750 for a while ended up liking 14.2 the most. You just gotta play with things and se if there is a difference good or bad. As far as timing goes Stailjim had a post on the last page that really nails it and is deffinately worth reading.
