When you press the bump/creep button, the Nexus stops simply holding the trans-brake fully on and drives it at the duty cycle from this table instead. 0% means the trans-brake is completely released, and 100% means it's fully applied. Values in between partially release it, so the car creeps forward in a controlled way.
The table can be mapped in up to three dimensions, so you can vary the duty with other conditions rather than using one fixed number.
When you need it
It's for drag cars using the trans-brake function, where you want to inch into the beams without releasing the brake entirely.
What to check
- Start with duty close to fully applied and lower it gradually until the car creeps at a pace you can control.
- Test in a safe space before the track; too low a duty can let the car move more than you expect.
- Confirm the bump button input changes state cleanly in NSP.
