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.

Could I ask how long for repair and return to uk on a gauge that requires a new main led alpha/numerical screen, the gauge itself is working fine it just the readout has some dead pixels.

cobalt wideband afr,the led display has partial failed, ie some of the leds displaying numbers don't light up. I see others have had similar issues, is this an issue with these displays? I'm based in the UK so sending back for repair could be a hassle

Asked by: edsw
Thank you for contacting us and sorry for the problem. We certainly can evaluate the gauge and service it, but you would have to send it to us. While this form isn't required, it will show you the information required for sending it in. http://www.autometer.com/media/Service_Form.pdf

Good morning. I have a haltech Elite 1500 controlling all about my car. I am wondering if I wouldn't have any compatibility problems if i use 2-1/16" WIDEBAND PRO PLUS AIR/FUEL RATIO, 6:1-20:1 AFR, COBALT?

Asked by: Kael
Hi Kael, thank you so much for contacting us. I would not anticipate any issues integrating the output from this gauge with your Haltech system. I would however recommend looking at this version of the Cobalt Wideband for your application: http://www.autometer.com/2-1-16-wideband-pro-plus-w-sensor-cobalt.html It not only uses a quicker responding sensor, it has quite a bit more configuration options which will make your integration all the more simple. Hope this helps!
