19 Hellcat red eye, Lambda hpt data log vs afr gauge on dash

AFR/ lambda, Mental block.

1 divided .0722 is about 13.8 correct, for hellcat stoic , using the same formula I added PE based on this simple formula but my mind was still using old 14.7 stoic value wideband tunes, I think that is how I got so confused, I read the forums all day and got myself even more confused.

I think simple answer is, I Have not tuned in over a decade and have AFR based tunes stuck in my mind I got myself confused , Lambda is a mindset, I added more PE ill do some testing in the morning and hopefully get some track time in the evening, maybe my mental block will help someone else, I will post how I got it wrong once i make sure i have figured it out and my solution if anyone else is as dense as me:)
