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.

I have a SBC 400CI with a Weiand 671 and 2 Holley 650 cfm carbs in a 23T Bucket. 1. Do I need to install 2 gauges one for each side? 2. What should the air/ fuel be?
Hi, A single gauge will work fine in your application. We cannot tell you what the correct ratio should be with this blown motor. We advise checking with your engine builder. Thanks, Jim

Is there any way to send a signal to the gauge that the engine is running. This would start the heater process at that point instead of having the heater started before the engine is running and taking a chance that the sensor will be damaged on startup?
Thank you for your inquiry. There is no way to send such a signal to this gauge. You would need to have the red wire connected to a source that only sees power when the engine is running.

I have this gauge installed and have gone through 2 O2 sensors now due to heater failure. I am wondering if the heater circuit is controlled by the gauge so that it does not overheat if the ignition is on and the vehicle is not running.
Thank you for your question. The heater function is controlled by the gauge. Once the gauge goes through the calibration process the O2 sensor is heating and can foul out due to the constant heat with only keyed power. For further assistance please call our tech line at 866-248-6357

Is this gauge and sensor compatible with leaded race gas?
Thank you for your question. Unfortunately this is not compatible.

Will this gauge work with the LSU 4.9 sensor ? My LSU 4.2 sensor has failed can it be replaced with 4.9 unit.
Thank you for your question. No, this gauge is only compatible with the 4.2 sensor.

I am looking for this gauge to match the 2007 series "Marine Pro Comp" series in silver face with chrome ring, 2 1/16". Do you have something available? Thanks
Thank you for your question. Unfortunately, we have no marine wideband gauges in 2-1/16". The closest match would be #4370, however, that is not a marine gauge and is not water resistant.

I have this gauge in my car and the wiring diagram say that you can add a data logger. What sort of data logger will wire to this gauge?
Thank you for your question. This gauge has a 0-4v data logging output. You can use it with any data logger that will work with a 0-4v signal.
