Mirroring the functions of AutoMeter’s Street Wideband, the Digital Stepper Motor Wideband provides the most important functions necessary to make sure you’re extracting the most power possible, safely. An analog needle display integrates seamlessly with other gauges and easily illustrates rate of change as well as the actual value. 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.

Been dealing with autometer for months now, doing everything possible to get this to function. Will not heat up unless start boat twice, reads for 15sec. Then jumps to 14.2. had to run a toggle switch to reset without restarting boat. Got data and made adjustments to carb off readings. Got close but still fat as is read but blew a couple plugs out on water. Idled in 10 min. Gauge reading 10.5 real fat. Pulled plugs and every one was way lean. Luckily changed plugs and engine was not hurt, went back to original jetting that was way fat, but can deal with it then roasting a 20k Engine. DON'T PURCASE..

gauge would get stuck at 14.7 and will not move. Wasted two days re-checking all wiring / ground etc. I also tested sensor itself and it was sending proper voltage but the gauge still didn't work. I would expect better quality from 200$+ product ...
