FAST Wideband O2 Sensor Kits for SuperFlow Dynos

For years, if you wanted to use your dyno's powerful data acquisition system to display and record air/fuel ratios, you had to piece together an external standalone air/fuel meter, along with a custom-made wiring harness to get a proper signal to record. Seeing the need for an easier way, FAST developed a plug-and-play kit that makes it easy for owners of any SuperFlow 902, AutoDyn, or CycleDyn dyno to measure their test engine's air/fuel ratio. FAST wideband O2 sensor kits for SuperFlow dynos include a wideband oxygen sensor and an O2 sensor processing unit that plugs directly into the AMP-style connector harness on the dyno. Once you configure the dyno's analog channel for the fuel you're using, the dyno will begin to display and record the air/fuel ratio. Making it easy to use was a priority for FAST, so these sensor kits utilize fully automatic sensor calibration. No need to manually "free-air" calibrate the sensor; just turn the power on, and in just seconds these FAST units output an accurate and consistent air/fuel signal. Additionally, each sensor kit is a standalone unit—so using multiple kits for measuring all your engine's cylinders is a breeze. With industry leading plug-and-play installation, accuracy, and ease of use, it's clear that FAST wideband O2 sensor kits for SuperFlow dynos are the best choice for serious engine tuners.
