Taking the core features from AutoMeter’s Pro Wideband, the Street Wideband provides the most important functions necessary to make sure you’re extracting the most power possible, safely. 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.

Is this water resistant or water proof for a motorcycle

Asked by: Bikeguy
Good so far. Mine is mounted on the fork tube.

My 2004 Acura TSX is equipped with 1 upstream air/fuel sensor and 1 downstream O2 sensor. Why can't I purchase this gauge without the air/fuel sensor since my car already has one? I can just tap the OEM air/fuel sensor wire for a signal for the gauge.

Asked by: TwistedTSX
Thank you for your question. Very few of our gauges are available without sensors. Our gauges are designed to work with our sensors. If the gauge will likely have compatibility issues with another sensor, then we do not make it available without the sensor. If you have further questions regarding this, please contact our support team via this information: https://www.autometer.com/contacts

How many apms does this unit pull?

Asked by: topper
Hi Topper, thank you for connecting with us. For power you'll want to tap into a 12-volt power source that will support a 3-amp current draw. The power draw on a wideband gauge is much greater due to the power required to heat the O2 sensor. During normal operation it will usually pull around 1 to 1.5 amps.
