Yeah, I pulled over kinda on the side of a 4 lane. Hit start logging, waited for all this nonsense to happen, and when it was finally logging, I got out and did my run.
There is a noticeable lag from when you hit the start to data log, from when the gauge icons pop up, I couldn't guess why yours didn't work, but pull into a parking lot, hit data log and wait for the gauges to pop up. I don't know if that even addresses your issue though.
I found out I was not waiting long enough. New logs submitted, thanks for the insight.

Only complaint about the app, and I put it in the first post. The logger takes way too long.

I need to ask ZFG to tone down the 1-2 WOT shift, I feel like it is going to cause problems later in the vehicles life. Far too aggressive, it's more like a track shift.

On my ZFG tune, its a hard 1-2 only when you are in it drag race style. She will bark the tires lol.

In Sport mode it's more like a track shift, in Normal mode it's perfect for daily driving. I just don't want to shorten the life of the transmission on a '25.

This is how you do customer service:

Combatvet,

Hope you had a wonderful holiday!
To address the shift concern, you can submit a tune request for Adam’s direct feedback. Please follow the instructions in the attached document before submitting your request to ensure that all bases are covered— it’s imperative that the transmission fluid is checked and correct, and that any “learned behaviors” are ruled out before addressing transmission concerns via tuning.

Shift firmness is typically aligned with the power your setup requires. Firmer, faster shifts help prevent excessive wear and component degradation, supporting transmission longevity. Softer/slower shifts allow more drag, which can accelerate wear.

As always, please let us know if you have any additional questions!
Warm regards,

Sales Team
