2012 bikes do not have wideband sensors

 

Key point here: HD EFI is not a MAF system, it is akin to the early generation automobile air speed density EFI systems and it has limitations. Even if it were a MAF system, it would compensate better but it still would not self tune, the O2 sensors still only assist fuel regulation in the "cruise range", the way the engine breathes outside the cruise range requires manual adjustment of the base map to bring the AFR results back to a desireble result; this requires real time WB O2 sensors feedback which are typically incorporated into dymo tuning operations. Changing pipes and air cleaners doesn't simply change the amount of air that moves through the engine but also changes volumetric efficiencey, or the amount of air at a given RPM. Its not as simple as adding a fixed 10% air with pipes and a cleaner and then adding 10% more fuel across the board. For a proper tune the fuel must be ajusted manually across the map to accomodate the new volumetric efficiency requirements, via realtime AFR feedback and/or real time HP/TQ feed back AKA Dyno, and this my friends is absolutely not "unadulterated, 100% pure, undiluted Bull S*** also known as Pseudoscience".

 

Well said........

 

My bad. I was told by a member here that the 2012 had the wide band o2 sensors. Post deleted.

 

True, but the model is produced once the boundary conditions are normalized and measured, so HD had to make a complete set of measurements to start
