Programming-voltage requirement: certain ECU versions need an external voltage before writing. BitBox detects the relevant type and displays the required steps. This procedure requires a bench connection; consult the manual and instructional video.

Some Keihin R8C/M16C versions restrict reading and may produce an incomplete or invalid file. If reading reports a checksum error, do not write that file. Try FID 226 virtual reading. If the server has no matching file, open the ECU and read it with a suitable third-party programmer, or arrange reading with the developer.

Activation requires a BitSoftware USB dongle. Enter your existing dongle serial number in the serial number field at checkout.
