I'm installing a brand new autotune tomorrow seems pretty straight forward, I'm wondering though about the O2 sensor test that is mentioned in the install/structions. They refer to a function button or key , does anyone know which button they are talking about? And is the test really necessary? This may have been already asked but 327 pages, serioussly? lol

RPM Limiter
Well after reading every single post on this thread I think I'm burnt. I want to thank all of you for your input, I have learned a lot and almost every question i had has been answered.
However, for some reason my redline still hits around 5800 +/-. I have the RPM limiter set at 6200 in my tune and the settings on the PV itself and I've been doing DataLogs so I know things are working but I look at the Tach on the bike and on the gauges I have running on the PV and it still won't go to the 6200 mark. Anyone have this problem? My bike is a 2012 StreetGlide. Do I need to recalibrate my speedo or is it some glitch in the ECM that wont let the PV override it?
Thanks

One more thing, I've done a few auto tune logs and applied the changes. In the delta I show -1% avg and a max of -11%. What do the negatives mean? Am I doing something wrong. By the way I'm using autotune basic as I only have the stock narrow band sensors
Thanks in advance

Open teh current file first, then click "load compare" and select the tune that you started from. When you click "delta" the chart you see will be the difference + or - between the first tune to the 2nd.
Seeing negatives is not wrong, although I would think that seeing ALL negatives would be unusual. If you're down to seeing an average change of only 1% I'd say you're pretty much done, won't get much better than that.

I did a few more autotune logging sessions today and updated my map, then I hooked it up to the laptop and "smoothed" the VE tables and the spark advance tables. Reloaded it and flashed it to the ECM. Just got back from a ride and the bike runs great! It didn't run too bad before, but it's definately more "refined" now. I also finally took the time to run the cable up under the tank console and to my RAM mount so I can see what's going on, and I finally set up all of the gauges to my liking. Very cool!
Questions...Today is my first time "smoothing", but what the heck is interpolating?
Also, will I regret doing this on an unseasonably cool day (low 50's)? Will I need to do this again when the temps get hot next summer? Does ambient air temp really matter much once the bike is up to operating temperature?
Finally, the one thing I would still like to correct is a slight, almost imperceptible stumble when I crack the throttle from idle. Suggestions?

Interpolate is used when you don't have enough good data to accurately arrive at a good value. I think it looks to adjacent cells to compute what the correct value should be.
My bike hesitates when I whack the throttle when cold. That's the only time I notice it.
My VEs are at 1% or less. I last tuned in the warmer weather and had the same question as you. I will leave them alone and let the ECM do what it is designed to do. But then again tuning is so easy, why not.
