Why this guide matters
On CAN FD Hyundai, Kia and Genesis cars like the Ioniq 5 and EV6, sunnypilot speed control must put the radar to sleep. That switches off factory emergency braking, which is a real safety trade-off. ESCC for CAN FD is a small module being built to keep the radar awake, and this thread tracks its progress.

Quick answers
Questions people ask
Can I buy ESCC for my Ioniq 5 today?
No; as of September 2026 there is no product. Hardware is being built by xnor.shop while sunnypilot writes the software.
Is ESCC the same as the older Palisade module?
No; the older ESCC is for plain CAN cars like the 2020-22 Palisade. CAN FD cars need a different chip and firmware.
Should I use openpilot speed control without it?
That is your call; you keep the car's own smart cruise if you leave the alpha toggle off. Many owners wait.
