DESCRIPTION:

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.

For over a year now I been using this AFR 4370, all of the sudden it has been getting stuck at 14.7, I replaced the sensor with a new one, I check the ground and connection, still it is stuck at 14.7. What could be the problem?, can I buy another gauge?

Is this meter will fit in my Minicooper JCW 2005 ?

Asked by: Robie

Thank you for your question. There is no way of telling if the gauge will fit into a stock location on a vehicle. However this will fit any pod that uses a 2-1/16" (52mm) hole.

My A/F 4370 meter often moves between 8 and 9 on the dial without going operational after the engine is hot. But usually when I turn the engine off and immediately restart it, it functions. Suggestions?

Asked by: John S

Thank you for your question. The gauge bounces between 8 and 9 while the sensor is heating up. If the sensor never comes out of heating mode, ensure it is getting 13.5+ volts. The gauge will also bounce between 8-9 if it is getting no signal from the sensor. If the issue persists, contact our support team at 866.248.6357 or https://www.autometer.com/contacts

What is the difference between Ultra Lite and Ultra Lite II

Asked by: stlite

Thank you for your question. The Ultra-Lite series uses incandescent perimeter lighting, the Ultra-Lite II series uses through the dial LED lighting.

I lost my installation instructions. For data logging what is the AFR range associated with the 0-4V output? For examples is 4v=18AFT and 0V=8AFR. A copy of the installation instructions would be great if you could email it to me. Thank you

Asked by: Casey

Thank you so much for contacting us. On your output wire, 0 volts out equals 10.0 Air/Fuel Ratio, 4 volts out equals 18.0 Air/Fuel Ratio. The instructions are literally right above the questions button, or you can go directly to them here: http://www.autometer.com/media/manual/2650-1469.pdf Hope this helps!
