52mm (2-1/16") Wideband AFR + Boost Gauge — White OLED Display, Bosch LSU 4.9 (10:1-20:1 / -30 to +45 PSI)

Two of the most critical forced induction readings -- air/fuel ratio and boost pressure -- in a single 52mm gauge. The white OLED digital display in the center shows live AFR, while the bar graph LED ring around the outside tracks boost pressure in real time. One gauge hole. Two data streams.

Powered by a genuine Bosch LSU 4.9 5-wire heated wideband O2 sensor, this gauge measures AFR across a full 10.0:1 to 20.0:1 range with the accuracy that tuners rely on. The 0-5 volt analog output connects directly to data loggers and standalone ECUs.
