Hello folks. I recently installed a new Jackpot 2/1/2 head pipe, Stage 1 AC and a PowerVision running the narrowband sensors on my 2012 FLHTK. I've done a few Autotunes and my bike seems to be running great. A couple of observations though and hopefully someone here can clarify for me.
1. The map provided by Fuelmoto has changed considerably after a few tuning runs. I would have thought that my simple stage 1 would have been pretty dialed in to begin with. Use the compare as percent to view changes. Get them down to 2 or 3% and call it good. Some will get a close tune from a vendor and some won't. Don't use the vendor map as a gauge, as it doesn;t matter much. What matters is what your back to back tune run changes are showing.
2. I've done the "compare" using WinPV and only the VE tables are changing. Should anything else be? Since there are still changes taking place, should I continue to do Autotunes or is doing a handful of runs sufficient? Only VE should be changing. Those are the numbers that set the pace for future changes. Keep making runs until the changes are minimal, It's a moving target so don't expect to 0 changes, it won't happen.
3. Also looking at some of the other stuff, the AFR chart is basically at 14.4 across the board. It came set up this way...I thought it was supposed to be set at 14.6. I prefer to tune at stoich. Others tune at richer AFR's or bias. The sensors are designed to center at .450 volts so I tune there.
2. My MPG is down a bit from stock. Is that normal? I was getting about 45 and now I'm closer to 40. I think you'll get your MPG's back up once you get the VE's synch'd up.
I'm not complaining about any of this as I really didn't know what to expect. I realize that I may be able to do better with wideband sensors and/or letting a professional tune it. However, the bike runs great and I feel more power and it sounds different (better). I'm just wondering if my results are in line with what should be expected with Autotune Basic.
Thanks.
Wideband sensors aren't needed. Do some more tuning runs and get it going in the right direction. Professional tune is always going to outshine these DIY'er gadgets but you should still get a decent tune in 90% of the riding areas.
Thanks for the reply. Did the search, didn't come up with anything specific, which is why I posted a request for details. Guess no one that has done it has seen my post yet.
Here is what I use on my 2010 SESG. Notice that I set the Throttle Transition Gear to 6 so I use this table all the time.
Hey guys I'm new to all this and just installed a set of V&H big radius and tried to install my power vision. After I got the pipes on we hooked up the power vision and married it to the bike. Then we tried to flas a preconfigured tune and it says sorry there are non for my bike???!!!!!! What gives? It's an 06 heritage softail FLSTI. That had a open heavy breather and screaming eagle pipes when I bought it used at the local dealer.
So I just disconnected buttoned things up and took it on a test drive to gas station and parked it for the night. The new pipes sound AWESOME! And bike rode fine for the short distant. Def seem like I have more power just with the new V&H pipes.
Well when I got home I hooked my power vision back up to the laptop and checked the updates again just as I did the night before when I updated the firmware. All is good. So I went to dynos website manually downloaded a map they had on their site. For 06 softail 88ci the map that was for SE breather with V&H big radius saved it to slot 2 then went out and flashed my bike. It was late so didn't want to tick of the neighbor so I'll test out the tune tomorrow.
So why do you think the power vision doesn't have any pre conf tunes for my bike.

I compared your chart to mine and from 20% up your numbers are higher by a point. I'm not unhappy with the throttle response once I get rolling, and I may bump those numbers up and see if it provides more fun... but our 2.5 column is the same, and I think that's were I need the improvement.
Based on your chart I think I will try a half a point increase in the 2.5 column and see in I get improvement.
This fuel injection business is fantastic regarding how specific a tune one can create; but it's a bit much for my head to handle.
I'll be going back to a carb on my next project!
I have a question about EITMS. I have a 2011 RKC just got my Power Vision and in the Quick Tune adjustments my EITMS is not selected and I can't select it. I made sure it is activated on the bike, not sure why I can't select it???
Thanks for any info.
If I set my closed loop bias to 14.2 will this change the closed loop operation from stock setting (14.6 I believe) to 14.2?
Will the bike operate at a new 14.2 closed loop setting?
If so what would be the limits?
Can I use 13.8 as closed loop or would I be stretching the limits of the NBO2 sensors to far?
I tried searching but couldn't seem to find a direct answer, thanks.

My EITMS wasn't active on mine ether, I went into my tune and activated it under switches and made sure it was selected under the quick tune tweaks tab, it's working fine now.

What bike are you working on? 14.2 is just above .800 mv. Why would you even consider running an 02 at that voltage? All this has been covered many times. Best if you spend a few hours studying up on this stuff. I'm not trying to sound negative. But with those kinds of questions I wouldn't be messing with any bike just yet. Take your time and study up so you can learn in some sort of orderly fashion.

Because the Vision is basically made to be used on bikes that came stock with O2 sensors. To do so would be a LOT of work for them, because there was no such thing as a PV in 06. IIRC, there is some kind of tool one can use to take a PC3 calibration and convert it to PV form.

If my assumption is correct that's exactly what DJ is doing. Many of their canned maps for the PV say "PC Import" in the description area when a tune is opened.
