anyone like their Power Vision tune better BEFORE autotune?

You would not gain anything by enabling Adaptive Control and starting with Auto Tune Basic again
When you enable Auto Tune with the PV it always runs with the Adaptive Fuel disabled.
Here are the changes the PV ENable Auto Tune does to the tune-

Page 9 from link above:
AutoTune Basic—automatically applies a .pvv to the tune that does the following:
• Sets the base fuel table to 14.6 for AFR based calibrations and .982 for lambda based
calibrations.
• Disables AE/DE/EITMS/PE/Adaptive Control.
• Retards 4 degrees of timing.
• Bias the close loop range to .700mv on AFR based calibrations.
General
• Sets calib to PVAT (Session Number).
• Clears adaptive fuel tables after flashing.

OR
Load the 8x Auto tune into win PV , enable adaptive control. , save the tune to the PV then flash the sporty to leave the adaptive to do its magic.
Im swaying go with option. 2 🤔
Thanks guys for all Your great advice

Auto tune session with no adaptive control option
Then I loaded one of the original tunes that I had received from jamie at FM , and had more of the same
With no option for adaptive control.
Once I loaded a copy of my original tune or a tune from dynajet, I got this
Original tune , Advanced tune from dynajet screen
I even enabled hidden files and folders in windows just Incase I was missing something, but alas no joy there.
What am I not looking at ? , Should an email to FM be required or should I just dump the FM tune and run with a dynajet map and auto it then enable adaptive control after the flash.
This is starting to **** me off 🤨
Thanks for all ya help,
Wiz 🍸

Make sure your PV Firmware, tune DB and WinPV Software are all up to date.
Connect the PV to the computer with the USB cable.
Open WinPV, from the Setup Menu. choose check for updates.
WinPV will close, the PVUpdate Client should open, update the software / firmware / Tune DB.
Save a copy of your tune with a new file name.
Open the new file.
On the PowerVision menu choose "Update Tune using PV"
You should see all the tune items available.
Connect the PV to the computer with the USB cable.
Open WinPV, from the Setup Menu. choose check for updates.

Other than that when in open loop 4000+ rpm the air/ fuel is left unadjusted and souly run from flashed programming ?.
Theres more to this caper than meets the eye 😜

Ok, now correct me if I’m wrong but am I understanding this correctly?, That auto tune is only going to correct air / fuel in closed loop: IE 4000rpm and below using input from the o2 sensors.
Other than that when in open loop 4000+ rpm the air/ fuel is left unadjusted and souly run from flashed programming ?.

So it will adjust the VE table over 4000 rpms.
When you "export learned" the PV sets the AFR, Closed loop bias and ignition tables back to the original values, adjusts the VE Table with the changes then you flash the updated tune to the ECU.

The PV Auto Tune with NB O2 Sensors sets the entire AFR table to closed loop while calculating new VE Values.
So it will adjust the VE table over 4000 rpms.

I installed and fresh copy of Windows 7 on my notebook computer ( this is my tuner pc ), Went to dynajet and installed the latest version of win PV, did all the updates and really all that was needed updating was my tune database.
Under win PV I opened my Autotune 8 file and from the oil down menu selected edit / change tune using win PV, And guess what. No change in the options I originally had .
I loaded all auto tune files and both FM tunes and there was no option to activate adaptive control.
Is this a secret, that This option is not available in any FM packet tunes ? And it’s kinda funny that FM hasn’t chimed in ,in this post to clear up any confusion.
Im going to go with a tune from dynajet as suggested for another poster, As this has all the folders and files available to adjust.
Just don’t understand as to why I have to search high and low for the adaptive control option when it should be right under my nose.
Once again guys. Thank you for all your help , And truly greatfull for all your input.
Cheers 🍺

I have not read all the above posts...but, just from the above bolded...the adaptive function is something the ECM does...NOT the PV.
I believe the only control the PV has, in regards to adaptive learning, is when you're loading a new tune and the PV asks if you want to Reset Learned Fuel Trim Values. See pic below.
Also, see post #37 above to see what all the ECM (not the PV) does in regards to adaptive learning.
There may be more in the PV regarding adaptive learning, but none I am thinking of right now.
