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.  

 

 

 

 

Setting up data logging in Livelink:

MAP Based: 

RPM

 

Air Manifold Absolute Pressure

 

Barometric Pressure

 

Load At WOT (can substitute with Load At WOT Based On Mapping if LOAD At WOT not available)   

 

Short Term Fuel Trim Bank 1

 

************************************

Blowthrough Enabled: 

Air Exhaust Back Pressure

MAF Based:

RPM

 

Barometric Pressure

 

Load At WOT (can substitute with Load At WOT Based On Mapping if LOAD At WOT not available)   

 

Short Term Fuel Trim Bank 1

 

Load

 

 

After gathering a data log of test desired. Go back to Advantage 3 tune file that was used for testing. Open the new tab at the top Tuning Tools. 

 

 

Then select Ford Speed Density Calculator.

 

 

Then select the tune file to be applied to from the drop down menu.  

 

 

Then select the log file to be processed.

 

 

Then select the weighting factor to apply calculation to.  

 

 

Lastly select Apply Calculation  

 

The calculation is directly applied to the applicable tables related to the calculation.  

 

If you want to stop at any point before selecting Apply Calculation, you can select Start Over. That will take you back to the beginning.  

 

 

After you are done, reload stock ADAPTIVE LEARNING, CLOSED LOOP BIAS BANK 1 (2 IF APPLIES),

CLOSED LOOP FEED FORWARD BIAS BANK 1 (2 IF APPLIES), WEIGHTING FACTORS that apply.
