Thanks, I called FM today and they verified exactly what you said for the colors. The 2nd AT run was about 45 minutes, and the weird thing is I was getting a VE:+ flashing on the logging screen some of the time which indicates it's changing between cells or conditions changing too quickly. But after getting home I saved the AT to a new slot and then pulled it and the first run off the PV and viewed them in WinPV. Doing the compare I got some adjustments in the Front and Rear VE, mostly in the 2-3% range but some cells are still >5%.
So it looks like the 2nd run was working at least some of the time.
I am going to make another run and see how it goes, then keep going to get all the cells <5%. Then I will start on my timing.
Sad news is they are calling for 2-4" of that white crap tonight and tomorrow

Any ideas what would be causing knock events only on the rear cylinder?
I have run my logs through log tuner several times due to some pinging I started hearing recently (that wasn't there before). Everytime LT calculates the new pvv, only the rear is showing knock events. Nothing up front.
I've also had a couple of back fires when letting off the throttle suddenly at higher rpms, which didn't used to happen.

At that point there's nothing else the software can do for you. What needs to happen next is go for a nice ride and pay attention to what the bike is telling you. Any vibes in the bars, pegs, floorboards? Any blurriness if the mirrors? If so, those areas might need a degree or two pulled out. Then smooth again. When I say smooth I don't mean use the smooth function. The smooth function will mess up your table. Just blend, manually, any small changes you made, to the surrounding cells on each side, top and bottom.

Yes it does. I did an install to confirm this before I included the link.

The second run was probably working all the time. keep in mind, on the second run if you hit a cell(s) that you didn't reach out to on the first run it will show a high percentage. Normally, you'll see the biggest changes on the first run, or first time a cell is hit with enough hits.
I know there has been a lot of discussion on timing runs in these 580 pages, but I captured a short log just to see what it looks like in Xcel.
Will the knock retard be shown in the "Spark Knock F" and "Spark Knock R" columns?
Or is there some other signal I should be capturing when I start doing timing runs?
Right now I have a ping at 2700-3000 when rolling on the throttle uphill and that was at 55 degrees outside, so I am sure I need to remove some timing in some places in the map. BTW....This was the case when I had the PCV connected using one of FM's maps, ended up pulling 2 degrees out in the 2600-3000 range at TP 40-80.
But I will wait until I have the VE's dialed in before tackling this.

I'm doing something wrong
Hi Folks,
I have done 3 - 30 to 50 min auto tune runs and saved them to a different slot each time. When I load them into WinPV and compare them there are no changes made at all. Any idea what I am doing wrong ?
I am running a 2013 Breakout with Monster Thunder QQ baffles in the stock pipes with the guts removed. I like the looks of the stock pipes, but hated the sound.
Thanks for any help.

After you saved the first autotune run, did you load this new file into the ECM? Each time you AT and save to a new slot, you have to upload to the ECM. When you compare, you are looking at the new tune vs the tune the new one was created from.

Could be anything causing a rear hit. Or just on the front, for that matter. Just let LT reduce it in your cal. Keep track of every cell, on every data log, that LT is pulling timing. Then once you get it where it stops pinging pull another 2 or 3 degrees in those cells. Once you do that look at how your curve looks and add .5 or 1, or pull .5 or 1, and get a nice smooth curve. Then do a final data log and make sure no knock hits.
At that point there's nothing else the software can do for you. What needs to happen next is go for a nice ride and pay attention to what the bike is telling you. Any vibes in the bars, pegs, floorboards? Any blurriness if the mirrors? If so, those areas might need a degree or two pulled out. Then smooth again.

Maybe the warming weather and summer fuel mix had an effect. I dunno.
Anyway, I just flashed the latest LT changes and will log the next few commutes and see what happens.

Cap or Scale
Hey guys after a run I always have a half dozen cells in each cylinder that end up capped. Do you guys recommend I continue to cap or should I scale my VE's? Or is this a try it and see scenario?

HI, Thanks for trying to help. Yes, I have flashed them to the ECM. When I run AutoTune I get values popping into the cells on the Green Screen. At th end of a run I save them to a slot. When I hook up my computer and read the tune into WinPV nothing has changed. I have 5 runs so far and when I compare them they are all the same. I am starting to think my PV is not writing the new tune to the unit. I guess I will call DynoJet Monday and see what they think.

Hey guys, so I've got a question off the current topic but regarding tuning with the PV.
So I use my PV with autotune basic, and have tweaked my AFR tables manually as well. But I'm a little confused about the distinction between closed and open loop with our tweaked tables. So a stock ECM in closed loop is always going to aim for stoichiometric. Since I have been tweaking my tables, I have been under the assumption that the ECM is always trying to aim for the AFR I have set in each cell, even in closed loop. But I keep reading that once in closed loop it is always aiming for stoich. So is this true? And if so, what is the point of us even tweaking and autotuning the closed loop areas of the table, if the ECM is just going to go for stoich anyway.
Which brings up the question...would it not be better to just disable closed loop when we have a tuner like the PV? My 04 Wide Glide has no O2 sensors, and I have never had any decel popping and it even seems to run smoother than my tweaked 13 FB at times. I assume you get better fuel economy with closed loop enabled. Also, using the O2 sensors might be the only way for it to adjust for changes in altitude, right?
