Compares the last write attempt with the next frame of the same ID and mux. It detects overwrites; it does not prove ECU acceptance.

Configuration and safety

Built-in nag suppression

Party CAN 0x370 only. A uses fixed +1.80 Nm. B cycles +1.80/+1.50/-1.50/-1.80 Nm with 1 s burst and 1.5 s pause. C uses fresh DAS status (0x399) and valid 0x129 steering context; stale or invalid context blocks writes. HW4 supports A/B; Mode C remains blocked after reported take-over and control faults. Built into firmware; plugins are not used.

Summon-only injection is for newer Tesla software where normal injection may interfere with Autopilot. It allows writes only while fresh CAN state confirms Park at 0 km/h or active Summon, and blocks on missing, stale, invalid, or contradictory state. Signal behavior can differ by vehicle and software version; treat this as beta.

In SavvyCAN: Connection → Add Connection → Serial Connection (GVRET), select this board’s USB serial port, 115200 baud. Once SavvyCAN connects, text logging is suppressed so binary GVRET frames remain clean. One 500 kbit/s CAN bus is exposed; the reference command set is read-only.
