I've been thinking - which can be a dangerous thing!
If we pull the flies and have an aftermarket exhaust/muffler fitted (AreaP, 2Bros, Muzzy etc) will the O2 sensors on the UK-spec bikes be able to modify the mapping in the ECU to cope with the mixture changes, through the rev range? Bearing in mind that the cats and standard air filter are still fitted, therefore there will only be minor adjustments to engine breathing. Any of you tech guys have any ideas about this.
I assume (dangerous again!) that the standard ECU uses a number of different maps depending on gear selection and then these maps are modified by the feedback from the O2 sensors?
The truth is out there.......somewhere??
