The CRF450R PGM-FI system has built-in correction for changes in air temperature and barometric pressure.
The Honda PGM-FI Setting Tool Allows the riders even more control over fuel delivery and ignition timing by parameters of throttle opening and engine speed, to suit the riders’ specific needs.
Programming the PGM-FI is simple, requiring just a laptop computer. Changes to the fuel and ignition timing settings are entered on the laptop and then downloaded to the PGM-FI unit by serial USB interface.
In the 2017 model, an engine mode selection button is adopted and it can change to three modes; standard and smooth, aggressive power modes, the same as with the 2015/2016 models.
If PGM-FI setting tool is used, the setting in the 2 modes (smooth and aggressive) can be changed.
