Steering improvements¶
zoompilot learns how your car steers at each speed, so it steers more consistently. Mazdas also get torque limits and a tune matched to their steering motor.
speed-dependent steering¶
Self-Tune learns your car's steering response and friction for each speed range and blends them as you drive. Steering adapts over the first few drives. It works only on cars with torque-based steering. Small and large driving models keep separate tunes.
On a supported Mazda, torque control and Self-Tune are on by default. Leave them on: Settings → Steering → torque control (comma 3X: Customize Torque Params). Speed-dependent learning runs with Self-Tune and has no switch of its own. On other brands, check that both are available and on.
on Mazda¶
zoompilot matches its torque limits to the Mazda steering motor's capacity and uses its own tune (v2.0 for small models). Expect more assistance at low speed and fewer small corrections on the highway. The motor still has a limit; steer through sharp curves yourself.
A compatible Mazda EPS (2022+) can assist down to a stop. An older EPS gets the same tune but stops assisting below about 28 mph (45 km/h). Model year alone does not identify the motor; zoompilot checks the car's hardware and firmware. Check your car.
If steering feels wrong, see troubleshooting.
custom tune¶
Almost nobody needs this. Leave Enable Custom Tuning and Manual Real-Time Tuning off and let Self-Tune learn.
- Enable Custom Tuning starts from your own Lateral Acceleration Factor and Friction instead of the car's defaults. Self-Tune still learns from there. Higher lateral acceleration steers with less torque; higher friction adds torque for small corrections.
- Manual Real-Time Tuning steers with your values at every speed, ignoring Self-Tune. Changes apply within seconds, even while driving.
Both are under Settings → Steering (comma 4: torque control → custom tune). They can make steering worse; to undo, park and turn both off.
