What is not published

The AMPSEAL pin map for V4 is TBD. Do not copy F7 pin numbers onto a V4 connector. Application notes that list core-efi-v4 mean the engine fits the channel count. The harness still has to be drawn from a confirmed V4 pinout.

H-bridges (electronic throttle or a bipolar stepper) are documented on Race Core F7. Whether V4 has the same H-bridges is TBD. Do not land a DBW motor on V4 until that output exists on the lid.

USB power rules follow the ECU you have. Do not power an ECU from the USB plug.
