Power Vision Question
You guys that are using the Power Vision......
How many times do you use that "auto-tune" function?
I did the auto-tune function and went for about an hour long ride and varied the riding with "in-town" & "highway" and "go-fast" and then downloaded the new adjustments to the ECM. Is this good enough or does it help to do the auto-tune function several times?
NOTE: I'm not using wide-band sensors..... just OEM.

So when you say you ran it 4 times..... did you just keep rewriting the previous autotune or did you just use a new slot for each attempt?

Each time you autotune, you should use with the last autotune corrected tune......
I run the bike normally do for about 80% of the autotune run. Then I try to fit in a couple of full throttle, roll-on accelerations. I do this to fill the cells I don't usually hit during my normal riding style. My runs last about 30-40 minutes and incorporate freeway cruising, curves, and hills.
When finished with an autotune, one of the pages of data will show you the average percent of change.... once you get to 4% average change, you're about as close as you're gonna get with basic autotune. Any more autotuning after that and you'll be chasing your tail....
I had a Fuelmoto map for my '12 Ultra with a stage II (a/c, cams, exhaust). After one 20 min. basic auto tune run, I was at 4% average change.... that was one good map!

I have the AT Pro with Wide band sensors, I ran AT 3 times. The third time my entire screen was green.
You should run AT until you get 5% or less change in the tune.
Run AT, save tune, use saved tune and rerun AT, repeat until happy.

HI, when we finished the auto tune, power vision offer two optiones for the new auto tuned map. We must select SCALE or CAP.
In threads of hdforum spain, the people says the correct is made two auto tunes in scale, and the nexts in cap. It´s correctly?

Are you guys still getting decel popping through your exhaust even after being tuned? Mine pops even after 2 rounds of the "auto-tune"..... Is it normal on these bikes to have a bit of popping?
