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.

Some of the LED lights on the gauge display no longer illuminate, rendering reading the gauge useless. Please let me know how this can be corrected. Thank you.

Does this gauge allow you to change colors like the analog elite series gauges? Primarily the digital display? I have the oil temp gauge and like it a lot. I was able to set it up so that it closely matches my factory gauges in appearance.

Asked by: Jmc1le
Honestly I haven't installed them I have others that I did and I don't think you can change colors

I there a way to run this on duel exhaust with an o2 sensor in each pipe?

Asked by: Luv2drift
Thank you for your question. Unfortunately, this is not a dual channel wideband and cannot read two sensors simultaneously.

Can it be used for a motorcycle and is waterproof 

Asked by: Dbcooper
Thank you for your question. We would not recommend using it on a motorcycle as it is not weather resistant at all.

The “Additional Notes” tab indicates a 0-5V data but the instructions pdf indicate a 0-4v output. Which is correct?

Asked by: feldme
Thank you for your question. It is 0-4v. I apologize for the misunderstanding on the website, we will get that fixed. It is a 0-4v output signal.
