Recovery Time

Nexus Series Firmware Help › Transmission › Flat ShiftUpdated Sep 2026

After a flat shift, power has to come back. Recovery Time sets how quickly the Nexus fades out its cuts and timing changes once the shift is done, which decides whether the next gear hooks up smoothly or with a jolt.

What Recovery Time controls

During a flat shift the Nexus uses cuts, timing corrections or both to unload the gearbox so the next gear can go in with your foot still down. When the shift is finished, it has to give that power back. If your Recovery Method includes a ramp out, Recovery Time sets how long it takes for those cuts and timing corrections to fade away completely.

It is usually somewhere between 10 and 100 milliseconds, and you can map it up to 3D, so it can change with things like gear or RPM.

Choosing a value

  • Shorter: power comes back almost at once. Fast, but it can shock the driveline or break the tires loose, especially in lower gears.
  • Longer: smoother reapplication, easier on parts and traction, at the cost of a slightly softer feel after each shift.
Our starting point

Begin toward the longer end of the typical range, then shorten it in small steps while watching logs for wheelspin or driveline shock after each shift. Lower gears usually want a gentler ramp than higher gears.

Recovery Time works alongside the rest of the flat shift setup, including ignition retard, percentage cut and torque reduction time. The input side is covered in flat shift wiring.
