It turns out that if you take the VE times the AFF times the CLI you get VE New
If you turn off AFF then what you end up with
VE times 1.00 times the CLI and you get VE New
If you turn off AFF in the code then you get
VE times 1.00 times 1.00 and you get VE New or VE = VE New
This can all be proved in MegaLogViewer HD fairly easily.
Have fun tuning.

Before you start, notice that the VE numbers drop off, outside of the closed-loop area (because your tuner hasn't been able to reach there yet). I recommend bumping up the VEs in these areas to match (or exceed) the highest numbers that you achieved in the previous closed-loop area. That will keep you out of danger of running WAY too lean on your tuning runs.
I recommend using the values from ABOVE the red line, enter those numbers in all the cells BELOW the red line (and to the right of the 3000 to 4000 range). Even if you go way higher, it's safer to be rich than lean in this situation. Once you make your tuning runs, Log Tuner will trim your VEs, and you can set your AFRs back to normal.

Here is a screen-shot of a VE table. Numerous tuning runs have resulted in higher VE numbers in certain areas (pink and yellow). Notice the area circled in RED. This area is just outside of normal closed-loop operation, so there has never been any changes made to these cells. If you plan on expanding the closed-loop area (for tuning purposes), you run the risk of excessively lean conditions in these areas.

Very clear, I don't have the issue because my "smartune new VEs" are not that high so I will not have a problem when running the closed loop afr in the ranges over 4000 rpm.
See my VE table ( front cylinder ) , the rows over 4000 rpm and 80 kpa are still unchanged.

Either tune will work equally well and there is no difference in the tables exposed. Unlike other build strategies you can freely copy and paste tables between level 9 and level 44 calibrations, this is not recommended with other strategies.
When Log tuning you will want adaptive control on

What ??? Is that is still true??? I was under the impression adaptative control fuel should be : "0" !
I miss something somewhere in this thread?

Having adaptive on lets the ECU do it's thing on learning what the motor wants. It will start doing adaptive learning about 15 min into the ride after a fresh reload when you take the option to reset learned tables.

And do we want this to happen during dataloging for VE tuning ??

Tuning for spark advance
I just received my PV and have been going through the threads and instructions. Tuning for VE seems pretty straightforward as I did that on my previous bike with TTS. What I'm reading so far, is to take some timing out prior to logging as conditions may be lean. This makes sense for tuning VE's, but then you won't get any good feedback on timing/retard. Are most of you first tuning for VE and then putting timing back in to start tuning for spark advance? I'm presuming that PV uses knock detection to make timing recommendations. If it uses a different strategy, it would be interesting to learn more about that.
