Well, you can't find hesitation by looking at any table, IMO. That is unless you do something idiotic (like I did once) by applying no fuel to one area of the tune by accident. That'll cause hesitation every time.

Anyway, if you install the FM tune and do some datalog runs you could likely locate the cause. Have you done that yet? You say it is between 1800-2800, which is a pretty broad range, so does it hesitate any time the bike is in this range or just sporadically? How much throttle are you applying when this happens?

If you want to diagnose this, do a datalog run and send your original FM tune and the log files to one of us. You'll have to use email outside this forum since they don't allow attachments other than image files.

My question for the resident experts, is how do I add items (VE etc.) to the "Tune Items" list?

I only have a very few items listed under each category on the "Tune Items" list.

I'm not using Auto tune w/ the WB sensors at this time so I'm not sure where to get this info.

As for the hesitation, it is every time. I found a different tune that is working... but the "tweaker" in me, wants to understand what went wrong the first time, so that I can better understand both my bike and the PV tool.

I went out on a 35 minute ride with auto tune on. got home and turned auto tune off ad then re-flashed my ECM with the stored auto tune.

to my surprise, the data from the tune looks exactly like the one that Jamie sent me when I purchased the device.

Now I'm not sure if i did something wrong, or if it's just tuned properly
