What is needed to reset AFR on an 1125.When I look at the bike it is 100 in rear and 90 in front, want 100/100. |

What software are you using? ecmspy or tunerpro? I think you can only reset one of them and as I recall, it's the rear. You would need to put the bike back to totally stock condition and get it to re-learn and adjust back to 100/100 on it's own.
It's either that or have a dealer flash the ecm back to stock.
I'm assuming you already know all this stuff below.
quote:5.1.3.2 Closed Loop Learn
The Closed Loop Learn region is a subset of the Closed Loop region and is where the global correction, the AFV, is calculated to account for all other uncertainties not addressed, these may include; ambient pressure and sensor deterioration. The Closed Loop Learn region occurs at about 40 – 70mph with a steady throttle and is shown in Figure 6.
The fuel is metered the same as in the Closed Loop region, except after 23 iterations of a difference between EGO and AFV, the AFV is reset to equal the EGO correction. Note that the AFV is only calculated in this region when the engine temperature is between [ Calibration Mode Maximum Engine Temperature ] and [ Calibration Mode Minimum Engine Temperature ], see section 18.
Top of Section
5.1.3.3 Open Loop
Open Loop operation occurs outside the Closed Loop and Closed Loop Idle regions, see Figure 6.
Open Loop fuel is metered as in Closed Loop, substituting the AFV instead of EGO correction and applying an open loop factor, [ Open Loop Default Correction ].
The Open Loop region covers the TPS and RPM which are encountered during a transition from Closed Loop to Open Loop WOT and during deceleration. For the former, the AFR needs to provide a smooth transition to WOT and for the latter, the AFR needs to be very lean to ensure the engine returns to idle quickly, to increase the engine braking effect and to reduce the chance of popping and banging in the exhaust.
I think (can't prove it for sure without looking at the ecm data again) that the closed loop learn area is very similiar to an XB in that it's a very narrow range, maybe 2000 rpm.
Tuner pro may be better to work with on an 1125.
