Road load simulation: The Simulated Road Load control mode uses both the Vehicle's weight (in the units system they prefer) and its Coast Down G's (drag) in calculating (real-time) the viscous drag, aerodynamic drag, and rolling frictional losses for controlling the dynamometer's load vs. speed - time - and cumulative applied power. Further, the user has the ability to adjust the "Road Grade" (again during real-time testing) to simulate hills, headwinds, etc.

Steady State Testing: For tuning and diagnostic work which requires holding a vehicle at a specific RPM or MPH while using the throttle to work through the load range pinpointing trouble areas or fine tuning and engine management system.

Keep in mind we can report HP and Torque real-time during your entire test session!

Drag Race Simulation: Great for seeing how much HP it take your vehicle to complete the 1/4 mile and tune accordingly.

Drag Shift Simulation: For dialing in your shift points for the most cumulative HP.

The simulation simply takes the integral (cumulative total) of the Hp delivered up to each point in the test recording and uses that total power input - against your entered drag and weight data for the vehicle - to calculate how fast the vehicle would be going after that much elapsed time.

This speed is returned as an Engine RPM set point ($ ROAD) which the absorber is then commanded to hold.

Users can enter both the Vehicle's weight (in the units system they prefer) and its Coast Down G's (drag). The Simulated Road Load control mode then uses these parameters in calculating (real-time) the viscous drag, aerodynamic drag, and rolling frictional losses for controlling the dynamometer's load vs. speed - time - and cumulative applied power. Further, the user has the ability to adjust the "Road Grade" (again during real-time testing) to simulate hills, headwinds, etc.
