Taking the core features from AutoMeter’s Pro Wideband, the Street Wideband provides the most important functions necessary to make sure you’re extracting the most power possible, safely. Our advanced auto calibration system 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). Designed for gasoline applications, this wideband gauge provides the same degree of accuracy and response as the Pro version, but at a reduced cost. Data logging output is included for one wire or two wire systems. Our specially designed O2 sensor and wiring harness are included for ease of installation.
- Gauge kit includes custom tuned .1 AFR Resolution Bosch LSU4.2 Sensor, 8ft. wiring harness, 304 stainless steel weld-in bung, mounting hardware, and detailed instructions for installation
- 0-4v data output feed for ECU, data acquisition unit, or Laptop tuning
- Suitable for use with gasoline powered engines
- Digital segment display and LED radial bar graph display
- 12 and 16 volt compatible, compatible with nearly every street car or race car electrical system
- M18X1.5 Fitting and Plug
Rated 5 out of 5 by Mr Jerry from looks very nice, works well I bought the a/f gauge a month ago , and it looks and works great. It was very easy install , good instructions. I am very happy, and it compliments my factory Mazdaspeed Miata gauges well. I mounted it in my glove box with an Autometer boost gauge , and will be adding water temp, and oil pressure. It looks great when I open the glove box at night. It makes a nice addition to my car. Thanks

I purchased a vehicle with this AFR I need to get a replacement cable but do not see it listed how can I go about getting one.
J, You would need P/N: 5298 for a new harness. As for the sensor you would need P/N: 2243.

what O2 sensor does it come with and can we use our own O2 bosch 17018
The only difference between the 4.2 sensor that comes with this gauge and the 17018 that you have would be the wire length.

I am running leaded 110 octane race fuel. Your spec sheet says leaded fuel can damage the O2 sensor. Do you offer a different O2 sensor that I can use with leaded fuel so I can use this wide band air/fuel gauge?
We do not offer a gauge/O2 sensor that is specifically designed for leaded fuel. You can run our gauge and sensor, but it will dramatically reduce the sensor life.

Why is this referred to as a "street" gauge in the description?
Thank you for your question. Designed for gasoline applications, this wideband gauge provides the same degree of accuracy and response as the Pro version, but at a reduced cost. The Pro version is compatible with almost all fuel types.

do you only need to read one side can you do both at the same time
Thank you for your question. The Wideband only has one sensor to measure AFR. This can and only will measure your air to fuel ratio which in return will display a value based on the data.

I can't get nine working it's just flashing. Could you please send me wiring diagram. I have tried even hooking the brown wire to the battery
I would recommend giving our tech line a call at 866-248-6357 for assistance on this.

I don't know which gauge to get. Is there much of a difference between the Phantom #5779 vs. the Ultra-Lite 4379? Other than weight?
There actually is no difference between the two as it will only come down to cosmetic appearances.
