The Keihin EFI control unit with KTM part number 81241031100 (“ECU EFI 11”) replaces the older number 81241031000, which some models were fitted with from the factory.
Same control unit, different software
The control unit is the same on every model listed, but the software (maps) differs by model and model year. That is why every tuning file is adapted to the original software read from your bike.
