How should the switch points ramp up to 14.7? Should it be 250-300mv for just like 0,8,16 then quickly go up to 14.7 from there. Becuase you want it close to 14.7 going up a hill in a low gear right?
That's something that you'll need to figure out. The closed loop mode airflow is defined in the PCM. What you'll need to do is figure out what your airflow is at cruise, look up the corresponding closed loop mode and go from there.
