Hold the pedal / throttle in position, click the matching button (Idle / WOT / Closed / Open). The raw ADC value snaps into the calibration field below. Save to flash when you're happy.

Calibration (raw ADC)
Throttle map — pedal % → throttle %
5 break-points, linear between. Drag points up/down/left/right. The orange dot shows where the pedal currently is on the curve. Default = softer first 20 % (calmer in traffic), linear beyond. Apply to send to Pico, Save to flash to persist.
PID gains
P-only first; bring Kp up to crisp tracking without oscillation, then small Kd to damp, then Ki to kill steady-state error.
Test modes
Sweep drives the ETB open/closed end-to-end. Confirm the linkage moves correctly before you ever fit a running engine.
