VVE zone question, found nothing definitive on a search.

Newbie here tuning my 09 CTSV E67 via the LTFT STFT method, no wide band currently on the car, mods are full exhaust (headers/offroadpipe/Corsa sports), and Corsa cold air.

No problems setting up the tune to data-log or data-logging but when I go to change the VVE I get,

"The following zones: 17 23 29, are not supported by the data provided. Consider changing your axis to include the range of all the zones boundaries for the calibration. Calculating the coefficients with incomplete data could result in undesirable data."

And those zones are missing. My E38 Avalanche has it all there though.

What's my next move so I can add my changes and flash it? What do I have to alter?

Edit: and yes I set up my histogram axis and column to match the VVE table but those zones aren't on my VVE

You need more space/distance between your zone boundaries because the zone is too small.

increase your map axis by clicking it and picking a higher limit. I had your same exact problem and just needed to increase the axis limit

or you can manually alter the axis to what ever you would like

So I did some research and found I should be able to set it up with ZL1 zones and then entered my stock VVE tables into it. So I did that and it gave me all the zones I was missing. Haven't flashed it yet and drove it but I will soon. Hopefully this takes care of my issues and I can start to get the fuel trims in check

Just took it out for a ride to datalog and that seems to have done it, thanks for the help.

I tried just manually setting them up but I just didn't like how it was coming out but the ZL1 zones seem to work.

A VVE zone search landed me in this thread, and the ZL1 zone tables cured a troublesome CTSV cam tune right nicely. Thanks for taking the time to share this info.

Did you copzy ZL1 zones and paste into into your zone table? Then just copy vve table from my car to new vve zone map? Just trying to make sure I got this right
