your probably right about the firmware
The 999 ECU uses a Bi-dierectional CAN system, with the clocks acting as a Body computer and dealing with Atmospheric pressure and Air temp that the clocks transmit back to the ECU
The 1000 Sport uses a Single direction CAN system so the Atmospheric pressure and air temp sensor sends its signal directly to the ECU
I have a 999 ECU that runs my 620 Monster which no longer needs a transponder, ariel or even the clocks for it to run. The ECU reprogram/remap was done by Mark at BSD in Peterborough
