Not an O2 issue. Trims look fine in other gears. It's probably a firmware/map issue.

Also, rescale your AFRs by clicking the value, hit P, min 10 max 20.

So as random as this is... Guess what fixes the problem?
Bringing the car into redline before gear change...

Was out data logging it and kept getting the same results no matter the ol mapping...
Finally got frustrated started just revving it to the moon to see if it'd run out or power at redline... And bam, car ran perfectly, afrs started at 14.1 and enrich to 12.1 at redline for each gear

To make sure it wasn't coincidence I shifted out at 6,500 again and sure enough it sat on its ass In 3rd... Then did another pull directly after that, revving it out to 7,200 and just as I suspected, perfect...

Vishnu is still claiming O2 even after seeing datalogs... Lol

Vishnu insists it's O2's but it's not.

How many miles on the car? Fuel trims are getting higher in second gear and I am wondering if the LPFP is the weak link. It would be nice to see your AFR's too durning the time. You can re-scale them properly.
