Tuners and Builders - A question on Dyno Charts
#11
It doesn't look like 14.6 from where I'm sitting. That'd be the red line. The blue line is in the 13s everywhere except a blip about 2.7k. Definitely not a closed-loop pull, I'd say.

My dyno chart shows a distinctive dip at about 3K RPM.
Could this be the Adaptive Knock Control kicking in?
I have an 09 Ultra with 49-state 103 kit, se255 cams, SE/AC and -99 SE II mufflers with stock header pipes, TTS Mastertune.

The TTST and it's V-Tune feature are unparalleled IMO, but in the WOT/high load Open Loop areas the actual AFR needs to be measured.
Measured with a Dyno or an adequate portable/loggable AFR sampling device.
Separate front and rear samples need to be taken.
TBF makes a good point...something just doesn't add up.
Your red AFR line being this smooth (even with AFR graph scale tight like it is) in the mid 14's would appear the this run was made while bike was in Closed Loop (less than WOT).
Again, AFR at WOT is a pretty much a crap shoot without being sampled.

No, my first dyno run was just with the factory download that came with the kit (at additional expense ). It is nearly identical to the one I just updated below.
This Dyno run was after I installed a TTS Mastertune and old SE II mufflers, and ran 5 runs with vTune. Nearly identical to the factory download and factory mufflers.
I update the image to include the AFR, which stays pretty much at 14.6.
TTS File is UH205-000. A few tweaks such as +2 degrees across the board on the timing tables.

Working the ignition tables is a good thing.
Might want to put first things first though.
Get a good handle on the AFR side of things...then work with the ignition.
Consider the competent Dyno or portable AFR device route for a complete tune.
As was said, there's a lot to be told about reviewing your DM files too.
What Data Type you select to record can tell even more.
Big help too, (I'll be a broken record here) print virtually all the TTST Help files (Master Tune help files, Data Mode help files V-Tune help files) and thoroughly read them...as many times as necessary.
With the TTST your on the right track. You'll get there.
