Triumph Keihin KTKSv2 Now in OBD with Flex

This new FLEX update introduces OBD programming support for Keihin KTKSv2 ECUs installed on Triumph motorcycles.

With the new protocol, technicians can connect directly to the diagnostic port of the vehicle and perform writing operations in OBD mode, without removing or opening the control unit.

This allows the programming procedure to be carried out directly on the motorcycle, reducing the number of steps required and simplifying workshop operations.

Depending on the application, the FLX2.68 connector may be required to use the protocol.
