Description

GA 2" AFR WDBND A C2

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.
