Mirroring the functions of AutoMeter’s Street Wideband, the Digital Stepper Motor Wideband provides the most important functions necessary to make sure you’re extracting the most power possible, safely. An analog needle display integrates seamlessly with other gauges and easily illustrates rate of change as well as the actual value. Our advanced auto calibration system automatically calibrates your gauge on every startup to assure you of the highest degree of accuracy over the entire lifespan of your sensor (no free air calibration is ever necessary). Designed for gasoline applications, this wideband gauge provides the same degree of accuracy and response as the Pro version, but at a reduced cost. Data logging output is included for one wire or two wire systems. Our specially designed O2 sensor and wiring harness are included for ease of installation.

Would it hurt the sensor if I put the gauge on a switch so I could see the air/fuel ratio only when I wanted to? The needle bouncing around all the time is distracting.

Asked by: kbelky
Turning the unit off during operation will only hurt the unit and will not show any benefits when powering it off. The unit will need to be powered on at all times when operating the vehicle.

Is this guage available with a more traditional incandescent bulb?

Asked by: AcampoDave
Not necessarily. Our regular Sport Comp Series may be the most comparable series that would feature traditional incandescent perimeter lighting.

Can this gauge come with a black bezel?

Asked by: Cookie
Thank you for your question. This does not come with a black bezel, but model #5970 has a black bezel and might be closer to what you're looking for.

is this gauge available in a 2 5/8" version with traditional classic bezel

Asked by: Carnut1cars
Thank you for your question. Unfortunately this is only available in a 2-1/16". As for the bezel it is not able to be changed since the traditional chrome bezel does not fit this gauge. For further assistance please call our tech line at 866-248-6357.
