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.

REVIEWS:

Rated 5 out of 5 by 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

QUESTIONS:

Why is this referred to as a "street" gauge in the description?

Asked by: SJW7
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

Asked by: bionicsweathog
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 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?

Asked by: Thomas66
There actually is no difference between the two as it will only come down to cosmetic appearances.

I've got an 85 CJ7 w/258 6 cyl. engine. The original O2 sensor was mounted in the exhaust manifold just above where the exhaust pipe connects (i.e. in a spot common to all cyl.). Would this be a suitable location to for the Autometer wide band monitor?

Asked by: shadow
Thank you for your question. You will want to install the O2 sensor roughly 6-8" past the collector.

Can this kit replace the stock sensor and send a narrow band signal to the stock ecu in my '01 miata, or do i have to install this completely separate from the stock sensor? If I change the ecu, does this kit have a wide band output to another ecu?

Asked by: Dalefishn
Thank you for your question. Unfortunately this unit can only send a wideband signal: 0v = 10.0, 4v = 17.0

Can this be mounted outside the car on the cowl?

Asked by: KFCSSP
Thank you for your inquiry. We don't advise mounting this gauge in a position where it is exposed to the weather. It is designed to mount inside the car.

Will this meter record a pass ,like drag racing 1/4 mile. If not what do you have that will??

Asked by: Kermit
Thank you for your question. It cannot record and playback a pass, however, it does have a 0-4v output that you can run to a data logger or other device to record the readings with. We have some wideband gauges, such as the #4397 which has peak recall you can use to see your max "lean" reading from a run, but we do not have anything that will record entire runs.
