you'll need to post the .csv data file for easiest review/response. best data is with traction control disabled, 3rd gear only (no kickdown), 2000 rpm to redline.

First, welcome.

You need to upload your CSV file, you can do that easily, just click go advanced, manage attachments.

Proper logs:

3rd gear, traction control off, 2k-redline, pedal 100% to floor, shift into 4th, END log.

Be safe
