Up Shift

UP shift is when you shift from a lower numbered gear to a higher numbered gear. This is typically done when you are picking up speed.

Take a quick look at the SilkDial for the current RPM A
Depress the clutch
Wait until the engine drops to RPM B
Release the clutch

Down Shift

Down shift is when you shift from a higher numbered gear to a lower numbered gear. This is typically done to get more torque to either accelerate or to slow down the car when descending a hill.

Take a quick look at the SilkDial for the current RPM C. and visually follow the Archimedean curve to RPM D
Depress the clutch
Briefly tap the gas panel to increase the engine to RPM D
Release the clutch

Reengage From Neutral

When going downhill, it is often advantageous to shift to Neutral to reduce the drag from the engine to improve fuel efficiency. Engine RPM will fall while the gears are not engaged and the vehicle speed remains high. At the end of the downhill, you will need to put the vehicle back in a gear, the vehicle may lurch back a bit due to mismatching engine RPM. Using the SlikDial, it is easy to get a smooth re-engagement.

Take note of the vehicle speed from the speedometer and locate the Archimedean spiral for that speed
Depress the clutch, and then put the stick in the desired gear
Depress the throttle to increase the engine RPM to the value indicated by the Archimedean spiral for the desired gear
Release the clutch

Drive With Shifting Paths

SlikDial can include a number of predetermined shift paths for most common ways of driving: green, aggressive, racing etc.

Pick the highlighted shift path that you like and start from the 1st gear ring, depress the gas pedal until the RPM reaches the beginning of the shift path
Depress the clutch, and let the RPM falls to the value indicated by the shift path on the 2^nd gear

Shift to the 2^nd gear, release the clutch and then depress the gas pedal and so on.
