There is no single "mixture adjustment" knob for the D-Jet FI.  It's all
controlled by the ECU.  For a properly-matched system (there were changes
over the years, so components must be compatible), you just need to be sure
your sensors are properly connected and the voltage is up where it should
be.  The head temp and air temp sensors are fairly robust and usually don't
fail.  Common culprits for rich FI is a pressure sensor hose that isn't
sealed well on both ends and low system voltage caused by a dying voltage
regulator.  Start by verifying these and the tune-up specs and valve
adjustment.
