fuel controller for the xvs950a
I have read through the service manual, and my understanding of the information there is that the built in FI system has the sensors to cope with any minor changes to Air/fuel ratio (due to for example changing the slipon, or the famous Airbox mod).
Indeed the onboard FI system should report any out of range parameters coming from the O2 sensor, the intake air pressure sensor and the air temperature sensor...as well as the ISC valve (which compensates for fuel/air ratio when idling)..
So, in theory, if I do the mods, and the FI system does not complain in any way, this means that I am ok, and I do not need the aftermarket fuel controllers to protect the engine from harm...
Of course if I want to change the mapping to an air/fuel ratio to one with particular characteristics, then that is another issue....
Is my understanding correct?
