Weird extremely RICH condition.

[xturbo1.5]

hey guys !!

I've been working on my SI 2017.

Something is happening right exactly when a change gear on a WOT pass, and it feels like a pause on power and the car sputters briefly just because the RICH condition during maybe 2-3 sec.

Passes were made on 3rd, exactly where 4th gear starts the AFR goes super rich.
I've attached a cuople of LOGS and Tune file.

Also I note, whatever value I write on WOT lambda adjustment table, the final AFR doesn't follow the value.
Maybe MAF sensor damaged?

Any help!

You may have to do some recalibration of the AFM. You should read about tuning the AFM: https://www.hondata.com/tech-tuning-boost-afm
