Thanks, your right temp folder was full...did not know it had a limit.

Let's us know if you have questions. Tuning with wideband autotune is similar.
I deleted one of the tune values out of the data logging, how do I get it back?

If you removed one of the fields that is being logged on the PV just go back into the menu like you did the first time and add it back it. Go to data logging, touch add,select channel to add, touch ok, exit. Next log will include the data.

I did a run on the bike and logged data but when I got back and hook it up to my computer and followed all the instructions in the post 778, it says Required channels missing from log

New VE (front) Channel

when I hit CAL tune.

Got that figured out and did another data run on my bike and followed all the instructions and when I get to the last step it says:
Table doesn't change and will match desired

Does that mean the calibration is good?

You should see a message for each Table - Front VE, Rear VE, AFR, Front Spark, Rear Spark. It is very common to see the Table doesn't change message for the Front and Rear Spark table. You should always see it for the AFR table. However, you should have changes to the Front and Rear VE table. You apply those changes to the calibration you were using and then start the process over with that as your base calibration.

Not necessarily... If the VE values were not significant enough of a change you will see the "matches desired" message. I have had this happen on occasion... but then I do another run where I change some of the external factors (i.e. speed, weather, hills, etc) and will see changes to the tune.

You will virtually always see a variance in VE during the calc tune process if you just compare the tables. Once you try to apply it to the tune in WinPV you will sometimes see the "table doesn't change. matches desired" message when the changes are minuscule.

I'll have to take your word for it. I have never seen the table doesn't change message when everything was working. Even "minuscule" changes to the VE tables generated the changes message for the VE tables.

To the OP, if there are no changes then you are good. However, if you didn't see "any" changes on your first run, then I would suspect something is wrong.

I've only seen it maybe 2-3x TOPS. When I compared the output on the calculated table to what was currently in the tune the VE changes were minuscule... Like fractions of fractions. I suspect it was due to the tuning runs being the same route ridden in much the same fashion back to back with no change in externals. That's just a guess.

I got the same message when I tried also. With this added.
Some tuning many not be able to be completed using this log"
Do I need to add New Ve (front and rear) to my logging or just ignore it?
