Slow, here is the long and drawn out:
We are an open looped bike. Our bike is tunable. If it came with an 02 we would be in closed loop and no matter what pc map you throw at it, it reverts back to the penultimate number or the Stoichiometric number of 14.7 or atmospheric zero, the fuel turns to water vapor or a harmless gas.
Under the seat we have a similar 02, but it's an elevation sensor. It senses when we ride up a mountain, have less air and that pressure turns the fueling to less fuel to match the matching process [of an 02] as to how to change the fueling. Since there is no sensor in the exhaust, but rather under the seat, we can pull those pipes right off and the bike will run just fine.
The next thing is when you install an AFR meter, plug the PAIR off and see the stock out the pipe is 14 AFR and with PAIR, the air is refired and the AFR runs in the 16 AFR. Lower the number the richer. That's one tune you can do without the pc is this 'for every action' a 16 AFR would have reentered the cylinder chamber, but you brought in a 14 or a 'richer reversion.' Trumped the pc tune is 1 down, one more to go.
When I lift, there is this vacuum causing effect on the intake air sensor. This lifting of, the closing of the main plates; the lower vacuum at that sensor; sends the AFR to a 13 AFR reading and this is the 2nd tuning step no one is catching is the lower the number the richer.
What the pc does is it moves the 14-no PAIR to a 13 to 12 AFR and that is where more gas is a stronger torque setting. This too brings a smoothing effect as you can tell by plugging off the PAIR and that rich reversion shows a change in air to fuel dynamics.
Once you understand some of this AFR [ratio] feeding of the beast, that pc is more of a doggie treat like bacon-bacon, bring on the pork or my piggy. So will a lean lift with PAIR in place hurt on lift? No. It's vacuum on lift that hits rich says: where do I need the pc?
I have a built in accel map on the OE side, I see that same heavy load on WOT is almost like lift and that load swinging the AFR needle rich. Do you still need a pc either PAIR'd or un-PAIR'd? No. If this for every action there is this fueling reaction still confuses you, install the stock pipe and when no one listens to turtle, he now says, 'it takes a Man to run stock pipes no pc.'
