How to use the Advantage 3 Ford speed density calculator
Setting up the calibration in Advantage 3:
Shut off adaptive learning. This will be located in ADAPTIVE LEARNING, SCALAR Change this value from 1 to 0.
Zero out the closed loop bias for O2 sensor/s. This will be located in O2 SENSOR, CLOSED LOOP BIAS BANK 1 (and Bank 2 if applies). And CLOSED LOOP FEED FORWARD BIAS BANK 1 (and Bank 2 if applies). Set the entire table to 0.
Set the weighting factor to be sampled. This will be located WEIGHTING FACTORS, INDIVIDUAL TABLES, SCALAR. Set all listed to 0 except single weighting factor to be sampled. (weighting factor count will vary depending on strategy)
Flash the vehicle with intended changes with the above included.
