The AFR number you are giving us is from the parameter ID in the PCM correct? You do not have a wideband sensor?
That pid is what the pcm is calculating....based on airflow/fuel mass.
It is what you used to compare to your wideband gauge to make sure that what the computer is commanding ie11 .4 FR is what is actually coming out of the engine. Then you know that your air and fuel calculations/tables are at least close to correct
Yes I am using a wideband thats where Im getting the 10.5.
