I bought and am insatlling the PV with Pro Tuner. I have a 09 Ultra, and I have a question. Behind the left side cover, where the diagnostic plug in is suppose to be, I have two options to plug into. One is open ended, and the other is right below the fuse box plugged into a sleeve. Which do I use to plug PV into? THX

 

The one that it fits.


The one plugged into the sleeve is where you would plug in a siren for the security system, if you have one.

 

it's open ended and has a protective rubber cap. Square in shape.

Also, go through all the videos on the Dynajet web site.

Thought so, thanks. Went home after posting that, apparently my Vision doesn't even have the AT feature loaded on it... Oh well.

 

when you load the PowerVision software and plug the PV into your computer with a USB cord, the very first thing you do is update the PV Client software.

Go to lower left of your computer: All Programs> Powervision> PV Update Client and then walk through the update process. It is easy. It will figure out what you have and then lead you through the update if there are any.

AT is on the 2nd screen once you click >Program Vehicle.

 

Give it 2 tanks of varying riding conditions to learn. The integrators will be doing their things for the short term trims right away but give a couple tanks to build a profile AF table. If you're running a closed loop tune you may feel it run a little better after a couple tanks. Or, if you got lucky and your VE's are close you may not feel it. Either way, it's learning and building a profile. If you're concerned about how far off your VE's are you could run a datalog showing your CLI %'s. If they're between 95% and 105% you'll be fine.

That should put you around 14.35 at cruise. Should be fine. The cruise areas usually tune up pretty nice so if you wanted to go richer I wouldn't hesitate to go open loop. I wouldn't go any richer and keep it in closed loop though. The efficiency of the sensors starts to degrade as you get to the flat spot of the slope.

 

Use AT for the VE's initially. Then use LT for timing. Then when timing is good make 1 or 2 final VE runs using LT. You always want to do things in the order of VE ...Timing...VE. My choice to do the final VE calibrations using LT is because LT is datalogging without any manipulations to timing, ie: reducing by 4*. There's nothing that says you MUST do it this way. You'd probably still be fine finalizing with AT. Just make sure you do it. Timing changes can make subtle changes to your VE's so it needs to be done to bring the VE's in line with your timing.

 

Has anybody started creating a library of maps? In particular, if anyone has a auto-tuned map for a 2013 fatboy with Arlen Ness big sucker and V&H BSS, could they post or PM the VE, AFR and timing tables for me? I'd like to compare with the stock and supplied maps to see how much variation people have seen in VE, the variation of AFR values people use and where they differ and how aggressive you can get on timing as some kind of guide before I start pushing it myself.

Thanks in advance

 

I believe that lambda values below 0.977 will automatically go to open loop. Though I don't know why anyone would use 0.976. I know the efficiency of the sensors on the AFR bikes that relied on Closed Loop Bias were greatly effected by how far away from the center value you went. Don't remember the numbers.

If anyone knows if the new and the old style sensors degrade the same way could they post. About all I do to check my sensors is datalog from time to time and check the O2 voltage (currently between 0.82 - 1.72) Not sure what this means but it shows that are switching on and off.

 

So I tried to do another AT this evening, and I had the most unusual results.

The AT seemed to go normally, with the exception that the green map screen of cells was displaying in a different differently. I figured it must have somehow gotten put in a different mode, so I "clicked" through the modes and found the normal mode that shows the "hits".

So the rest of the At went well and I exported learned cells, and saved the tune to the PV. Brought up WinPV and did a compare from the previous tune and all of the cells I didn't hit, we're all showing 10% delta (this is normally zero for me previously)

The other thing I noticed immediately was that the displacement of the new tune showed 107.4ci. I'd love to have 107 but I don't!

Any input? looks like this AT was a wasted of good gas.
