$6E (MAF) code, BLK LRN CELL shift oddity
I always thought the BLK LRN CELL in my TunerPro log referred to the LV8 cell # in the spark and AFR maps.
While working on a new tune, I found a change in the BLK LRN CELL and BLK LRN # but I can't find a mentionable difference in any other part of the data. The CELL # shifts from 1 to 0. The BLK LRN # goes from 128 to 136. The LV8 variable only changed by 1!
see attached log, sample 1750 to 1751

Why is it in the "0" cell with the LV8 reading 55 ? What variable is causing it to shift from cell #1 to #0? I need to understand that before I try to change the AFR in the "0" cell.

It depends upon how the option bit 0 of $C017 (option word 4) is set. If set to 0 then the airflow variable is used, if set to 1 then the LV8 variable is used.
