From I re-check again with NTCSEA about LCN2Kai speed-lock, they confirm me that LCN2Kai device for P32R THI (7612051265) have speed-lock.
Therefore it is the reason why they confuse. It make they have a question why LCN2Kai device for L12F year2 (7612051326) have no speed-lock even if use same software?
Please kindly advise to the customer.
