Knowing the exact air/fuel mixture running through your engine is the most important factor to extracting the highest levels of performance and durability. Not all wideband gauges are created equal. AutoMeter utilizes an advanced calibration method that 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). Compatible with nearly all fuel types, the AutoMeter Pro Wideband has a configurable display to pinpoint the exact range you want to keep an eye on. An advanced peak recall function and lean warning system make sure you’re safely making power, whether on the track or on the street. An automatically dimming display tailors light output for any condition. Data logging output is included for one wire or two wire systems in both lambda or AFR. Our specially designed O2 sensor and wiring harness are included for ease of installation. Quite simply, there isn’t a more accurate or easy to live with wideband gauge available on the market.

Hello, I bought this to run in my jet boat. I also bought an extension harness for the o2 sensor but it does not have the right plug. Do you make an extension for the o2? I want my gauge on the dash but the motor is in the rear of the boat

Asked by: JoesBoat
Unfortunately at this time we do not have an extension harness for the Pro Plus Wideband Gauges.

The picture shows the digital display in red. Is there an option to change colors for the digital display? Or to blue?

Asked by: AK-JJ
Thank you for your question. You cannot change the color of the display, however, part #6197 is the Cobalt version of this gauge and it has a blue display.

is it possible to hook up 2 sensors ?

Asked by: steve69
Thank you for your question. You cannot run 2 sensors simultaneously or with a switch. We can only recommend an actual dual channel wideband that you can find from our sister company, Innovate Motorsports:

Do these use the same harness/connector as older sport comp widebands. I have a 5yo SC WB in my hotrod and the harness is integrated into the vehicles harness and would be difficult to replace with a new gauge. Will the new gauge/sensor fit?

Asked by: Voluntas
Hi Voluntas, thank you so much for contacting us. Unfortunately with the addition of the new features, the harness is a bit different than the older style widebands. The connector has more pins and is slightly wider. Sorry for the bad news.
