Wideband AFR gauge with a large digital readout and selectable AFR or Lambda display. Designed with faster sensor frequency, faster analog output speed and enhanced heater control for high performance applications.
Quicker air fuel feedback - thanks to faster sensor frequency
Faster sensor frequency increases the rate at which the O2 sensor reports data, reducing lag between combustion events and displayed readings. The higher sampling rate leads to more frequent AFR updates on the display.
Allows timelier tuning adjustments and faster detection of mixture changes during throttle transitions, making transient tuning more precise.
More accurate ECU signalling - with faster analog output speed
Faster analog output speed reduces delay on the analog line to engine management, allowing AFR shifts to be communicated more quickly. The quicker output helps matching ECU responses to real-time combustion changes.
Improves closed loop responsiveness during transient conditions so tuning and corrections happen with less lag.
Stable sensor performance under boost - with enhanced heater control
Enhanced heater control maintains the sensor at optimal operating temperature, which is particularly important in forced induction and other high performance scenarios where sensors can cool or be exposed to varying exhaust temperatures.
Keeps AFR readings reliable under high load and boost, reducing false lean or rich readings while tuning or on the track.
