Most of the time ECU flashing works without a problem but there is always the
small chance that something could go wrong. ECUs from different
manufacturers all have their unique characteristics as well as potential
problems too.
The
Woolich Racing Tuned software is used to read/write information from an ECU and
uses different communication protocols based on the specific ECU.
Sometimes there are problems with the communication and an error like
"Failed to unlock protocol" is shown in the software.
This
error can occur on ECUs from different manufacturers.
If you see this error when working on a Harley Davidson ECU, please see this article: Diagnosing Harley Davidson "Failed to unlock protocol"
If
you see this error on a bike/ECU which is not a Harley Davidson, please Open a new Support
Ticket so that we can assist you further.
