What the table sets
The table is in milliseconds, and it can be mapped in up to 3D, so the time can change with things like RPM or gear. What the number actually means depends on the flat shift mode:
| Mode | What the time means |
|---|---|
| Timed | The whole length of the full torque cut. When the time is up, torque comes back, whether the shift has finished or not |
| Closed Loop (on ECUs that support it) | How long to keep the full cut going after the ECU sees the new gear. This extra moment lets the gear engage fully before torque returns |
How we tune it
In Timed mode, too short and the gearbox won't release the old gear cleanly, so shifts feel notchy or get missed. Too long and you lose drive and the car bogs between gears. Start a little long, then shorten it in steps while logging, until shifts are quick but still clean. In Closed Loop mode the ECU already knows when the gear changed, so the time here is usually a short hold, just enough for full engagement.
How torque returns after the cut is set in Recovery Time. See also the flat shift function, flat shift wiring, percentage cut and gear tolerance.
