About ELM327 MAF Healt Checker
The application connects to the engine control unit via ELM327 (Bluetooth or WiFi device), and using the live parameters it retrieves, it evaluates the health of the MAF sensor by comparing the airflow calculated using the SD algorithm in 3 different RPM ranges (1000 / 2000 / 3000 rpm) with the airflow measured by the MAF sensor. In addition to 5 different engine types, it also allows the user to define VE values.
With this application, problems such as:
* MAF sensor health
* IAT sensor health
* MAP sensor health
* Manifold air leak status
* EGR mechanical jamming/leakage status
* Air filter blockage
* Crankcase ventilation problem
can be detected.
The program is purely for preliminary diagnosis purposes. For a definitive diagnosis, you should perform a professional scan.
