Tuning with a Dynojet dyno has never been easier! With the addition of our new air/fuel ratio monitor, every dyno run can show you not only horsepower and torque, but also exact air/fuel ratio. This takes the guesswork out of fueling adjustments. The air/fuel ratio graph shows a rich/lean condition at each RPM during the dyno run.

Retrofittable to any existing Model 200 dynamometer, as well as any upgraded Model 100 or 150 dyno utilizing the new hardware stack and WinPEP software.

The air/fuel ratio monitor also includes a high temperature sample line with a dual pump assembly and moister separator.

Wide-Band O2 sensor has a range of 10.29:1 to 23.0:1. Specialized 6 wire heated and referenced sensor is self-calibrating for long, consistent life.
