XFI Wide-Band Auxiliary Air/Fuel Ratio Module

FAST™ engineers have developed a kit that makes it easy for anyone to measure an engine’s air/fuel ratio. This plug and play Universal Air/Fuel Ratio Module Kit allows your data acquisition system or dyno software to record and display air/fuel ratios. Since it uses fully automatic sensor calibration, there’s no need for manual “free-air” calibration that competitive units require. Additionally, each sensor kit is a standalone unit, so using multiple kits for measuring all your engine’s cylinders is easy. Compatible with FAST™ Digital Air/Fuel Meters.
