ExTuner
ExTuner - a tool for monitoring air-fuel ratio (AFR) and exhaust gas temperature (EGT) in one device!
Features:
- Availability of a graphic OLED display for displaying readings and navigation using a joystick
- Supports Bosch LSU 4.2, 4.9 sensors, as well as the most modern LSU ADV
- Protocol support Innovate LC1/LM2
- Ability to select fuel type for correct AFR display (petrol, diesel, LPG, CNG, methanol and ethanol)
- Free-air oxygen sensor calibration for high accuracy and aging considerations
- Oxygen sensor fault detection
- Emulation of a narrowband oxygen sensor signal (0-1V)
- Universal analog input 0-5V for displaying additional parameters (boost pressure, oil temperature, etc.)
- 0-5V analog outputs for AFR and EGT
- EGT temperature alarm
- USB interface for communication with a PC
- Proprietary PC software (setup, parameter recording, firmware update)

Monitoring AFR and EGT: two key parameters for perfect engine tuning.
Without accurate fuel mixture and exhaust temperature data, any tuning is a risky guesswork. Our device provides you with this data in real time, turning a complex task into a manageable process.
Why is this a must-have for engine tuning?
Control of mixture (AFR) and exhaust gas temperature: Simultaneous monitoring of AFR and EGT is the basis for safe and effective tuning.
Save on gauges: Built-in support for analog sensors (e.g. boost, oil temperature, etc.) eliminates the need to purchase additional gadgets.
Easily integrated into any system: Use the 0-5V analog outputs to transmit data to your ECU, data logger, or other equipment. Support for the popular Innovate protocol also expands integration options with any tuning software that supports this protocol!
- Safety and confidence in readings: Built-in sensor self-diagnostics allow for early detection of sensor malfunctions and provide early warning. Furthermore, oxygen sensor calibration in air, unlike using a built-in calibration resistor (as found in amateur controllers), allows for accurate AFR readings regardless of the sensor's mileage!
