Your dyno. Your starting point.

Import an image or PDF and trace the run. Work from your measured torque or power curve.

Every ratio matters.

Look up a vehicle or enter up to six gears, final drive, and tire size. Make the setup your own.

03 / SEE THE DIFFERENCE

Make a change. See the pull.

Drag the dyno curve and watch wheel force change. Overlay two setups to compare your options.

What would you change?
