The efiO2Meter application is used in conjunction with the efiO2Meter hardware module by efiLabs for the analysis of Air/Fuel Ratio (wide-band O2) exhaust gas data. The application provides an 8-channel graph for real-time and replay analysis of O2 sensor information. Furthermore, the application allows users to log O2 sensor information for later analysis.
The efiO2Meter hardware module uses the Bosch CJ125 sensor data preprocessor chip and the Bosch LSU 4.9 (and legacy LSU 4.2) UEGO sensors. This application uses the on-board Bluetooth module to wirelessly communicate with the instrument.
The efiO2Meter application and hardware module is the perfect tool to analyze and assist in tuning your internal combustion engine (carbureted and fuel-injected).
