AIRFLOW METERING
The Porsche 996 Turbo is equipped with one MAF (Mass Air Flow) sensor and a pre-throttle body charge
pressure sensor. The Infinity supports the factory mass airflow sensor and boost pressure sensor.
Users can also add a MAP (Manifold Absolute Pressure) sensor and use the speed density airflow
algorithm instead.
Note: If adding an external MAP sensor, users must disconnect the electrical connection from
the OEM Porsche boost pressure sensor to the Infinity.
Mass Airflow Setup
Setup Wizard
To enable MAF on the Infinity, use the setup wizard's "Engine" tab to select "0-5V MAF" or "Frequency
MAF" as the airflow calculation method. Users can choose a number of options for the main spark map
load axis. The example below shows "MassAirflow [gms/rev]" as the main spark load axis. The 996
Turbo base calibration will have this pre-configured for use on a stock 996 Turbo.
