Autometer GS 52mm AFR or LAMBDA Digital Wideband Air/Fuel Ratio PRO Wideband A/F Kit

Product 3878 DESCRIPTION:
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.

This can be used with the following:
Unleaded Gasoline

For the life of the sensor however there is no way to determine the life of the sensor for the fuel type you are using.

Renato,
The bung will need to be installed 8-10" away from the collector on the header. The O2 sensor installed in said bung, along with the gauge having +12.5v and ground.

Hi Austin, thank you so much for contacting us. The bezel on this gauge is what we refer to as a "bright anodized" finish. While it is more shiny than a brushed or stainless finish, it's not a full chrome. We could certainly do a special order for you it you'd like to have one built with a chrome bezel though. If you're interested, give us a ring at 866.248.6356 and we'll be happy to help.

Hi, I own this gauge and a couple of the “lights” burned out on the digital readout. I was wondering if I was able to get it sent out for repair or if I was able to purchase the gauge all by itself without any wiring or sensor. Thank you

Hi Dustin, thank you for contacting us. We're sorry for the lights that are not functioning properly. We do not sell just the gauge head, but we can absolutely service your gauge if you'd like to send it in. While this form is not required, it will give you some direction and the information we'll need if you send it in: http://www.autometer.com/media/Service_Form.pdf
