My setup:
2011 Fat Bob
V&H Slip-Ons
SE Heavy Breather

I completed three tuning sessions using the auto tune software. In my last run, all of my changes were less than 1%, so I figure I'm finished.

My bike actually feels weaker to me now. The sound wasn't near as deep and throaty as it was before I added the Mastertune and Heavy Breather. I feel like I'm ******* the motor when I'm riding 65-70 in 6th gear, but 5th gear at that speed feels like to much.

When I'm running 55 in 5th gear and give it a good bit of throttle, the bike feels much less responsive than it did previously.

I increased the acceleration enrichment and decreased the deceleration enrichment slightly. This helped bring things around a little bit, but I still feel like I'm missing some *oomph*.

I'm actually quite disappointed in my results and wonder if I'm missing something.

I reset all the values of the AFR and PE table back to original after running like the manual suggested. Am I correct in leaving the majority of the AFR values set to 14.6 for closed loop?

 

I left the majority of my cells closed loop, as the default map. It does sound different, I think better, after a tune, perhaps less of "harley" sound. My tune brought my 09 FatBob to life, however. Something is not right, perhaps something simple like forgetting to program the new map

Did you play with the cam timing? What CLB offset did you use? How has the mpg changed? Which starting cal did you use?

 

Thanks for the reply. I've double/triple checked that I programmed the new map. I even gave it a new ID, programmed it, then retrieved the info from the ECM to confirm the ID matched what I expected.

I didn't change the cam timing.

My steps:

Set all AFR values to 14.6.
Performed test run & gathered data.
Produced new data file.
Programmed ECM.
Test run 2, data file 2, programmed ECM.
Test run 3, data file 3, programmed ECM.

Set AFR and PE values back to default.

Disappointed with results.

Increased acceleration fuel enrichment slightly.
Decreased deceleration fuel enrichment slightly.
Increased idle RPM slightly.

Bike still seems underpowered.

 

If cam timing you speak of is the cam selector and it wasn't set then you should start all over again. Cam selector and analyze your IVO is your first step after saving your factory calibration.

Next are:

Set all AFR's (except for 100 kPa) to 14.6
Set Accel Enrichment to 0
Set Decel Enleanment to 0
Set CLB's to desired number (I like 684 in all cells, depends on the build)
Set Adaptive Knock to 0
Set PE mode to higher than rev limiter or 10,000

Save these changes as a new file, call it A-001

VTune A-001. After several runs you need to view your low EGR cells in the VTune generation file. Work with your EGR tables to smooth your VE 3D graphs for both cylinders.

on and on and on.....
