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.
- Gauge kit includes custom tuned .1 AFR Resolution Bosch LSU 4.9 Sensor, 8ft. wiring harness, 304 stainless steel weld-in bung, mounting hardware, and detailed instructions for installation
- 0-5v data and serial data outputs for ECU, data acquisition unit, or Laptop tuning
- User programmable range for Rich/Stoic/Lean conditions
- Peak recall/memory
- 10:1 to 20:1 AFR range for gasoline applications
- 12 and 16 volt compatible, compatible with nearly every street car or race car electrical system
- User Programmable Warning Function
- Display data in Lambda or numerical A/F ratio
- M18X1.5 Fitting and Plug
- Wire Harness
how can I test the sensor? mine has started acting up with weird readings all over the place. jumping around the sits at 20 for a time then is jumping between 11-16.the can is running just fine. hoping just a sensor and not the gauge
Hello, This may require some additional troubleshooting with our Tech Team via email or phone. Unfortunately, due to the nature of an O2 sensor, it's not necessarily easy to test without proper equipment. If this unit has worked fine for a long period and you just started seeing this issues, that does tend to more likely be a sensor. Check all of your harness and the small pins into the connectors as well. Thank you, Matt

do you offer AFR for methanol
Due to the range requirement for Methanol, our Pro and Pro Plus wideband will work. Our street series and analog won’t capture the proper range

Can this be used with leaded fuel?
Thank you for your question. None of our wideband O2 sensors are made to work with leaded fuel.

Can you please email me the part number for the 2-1/16" WIDEBAND PRO PLUS gauge with the white bezel. Thank you, Mark
Thank you for your question. We do not offer a wideband pro plus gauge with a white bezel. This gauge, the 4397, would be the closest match to what you are describing.

Can I run this on a carbureted e85 setup?
Hi Donovan, thank you so much for the question. Yes, the Pro Plus Wideband is compatible with E85 and can be adjusted so that the range is more applicable to the 9.8:1 stoichiometric point of E85.
