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.

Questions

Does the 7178 have backlight illumination like other C2 gauges?

Asked by: Rich13
Thank you for your inquiry. The 7178 dial face does not light up. The only lighting is the digital display and the LED bar display.

Can I extend the o2 sensor wires? My engine is in the back of a 4 seater sand rail

Asked by: Beene
Hi Beene, thank you for the question. We would highly advise against extending the wires on a wideband harness. We do offer a 25' harness, model 5253, as an optional item: https://www.autometer.com/wideband-afr-ext-length-harness-pro.html
