DATALOGGING  GUIDELINES

 

 

MASS AIRFLOW SENSOR CALIBRATION LOG:

(AKA MAF Cal)

****ALl Logs should include the default parameters preset in the ACCESSPORT****
 

  • The goal of this log is to dial in the closed loop / low load portion of the fuel curve.

  • In order to do this, we will need a log that shows airflow from low voltages, up to about 100 grams per second.

  • The logs do not have to be perfect. Please just do your best. 

 

1) Find a road that is safe to log

2) Set your AP so that the screen displays mass airflow grams per second

3) Put your car in second gear

4) Slowly depress the gas while  trying not to boost

5) Start to increase your grams per second and try to get to about 100 grams per second without boosting.

6) Depress the clutch, come to a stop and rev the engine to about 30 g.s.

7) Send me the log

 

 

 

 

 

aka Wide Open Throttle Log:
(aka WOT LOG)

****ALl Logs should include the default parameters preset in the ACCESSPORT****

1) Starting @ 2,500 rpm, push the accelerator pedal to the floor and stop @ or just before redline (in most cases, 6,700 rpm)
