Product Description
The new Revel VLS OLED gauge updates the previous model Tanabe Revel model with the new "VLS" branding. It offers several advantages to traditional LCD gauges, by providing a sharp OLED (Organic Light Emitting Diode) image and an undistorted viewing angle of nearly 170 degrees.

On top of that there is no backlighting required to see it at night, so the 52mm wideband A/F ratio gauge is slimmer and therefore fits in smaller spaces. The included Bosche LSU 4.9 oxygen sensor has an extremely accurate reading that can be installed using the included weld in bung.

Responsive, accurate, and high quality

I previously had an AEM UEGO but when I switched to the Revel wideband I was much happier. The AEM is a great gauge, but lacks the modern style that the Revel has with the OLED display. At times, I also found the aem was hard to read, as the color sweep wasn't very vivid. However, with the REVEL AFR the sweep is easy to see in my peripheral vision, allowing me to keep a constant watch on the road and on my AFR's while street tuning. Response time is excellent, and the gauge also has an output for both narrowband and wideband logging. The output also has its own ground to improve signal quality. I'm really picky about AFR gauges and this one is I'm happy with.
