another re-map after pipe and intake change observation
I came across an article and found this statement
Why is everyone pitching the need to remap if 07 and later o2 sensors are self compensating?
last week I went from stock mufflers on my 07 ultra to SE 4" mufflers. the next day I installed the stage 1 kit.
Bike runs fine. I also looked at some hp and torque graphs and saw very little happening below 3000 rpm, which is above where I spend most of my time.
Thinking of going DIY stage II and 103" along with switching to wide band 02 sensors.
On the 2007 and newer H-D’s, two O2 sensors are used, one in each pipe. When pipes and air cleaner modifications are made, the ECU’s on these 2007 and newer bikes can actually self-tune to compensate for those changes, and return the motor to a 14.7:1 AFR, as mandated by the EPA.
