UG Lean Burn indicator
Figured out by watching my Commanded AFR that at start up the car is as lean as it ever gets, 14.64-1 afr, or 1.000 on the Commanded AFR. Normal running has it in the .992-.997 range and by calculation a reading of .956 will get it to go sub 14.0 which has it running richer.
So, I set the Commanded AFR alarm to help alarm me when I get richer than 14.0-1.
This should help when I am on another page monitoring other functions.
Monitoring that one gauge has helped, had a 43.4 mpg tank and this tank is even better.
