Yes, but who cares? If it runs well, why would you want to put a stock tune in it or change it at all?
very correct, but if our targets AFR are right and EGO is always low it must mean that 'Fuel maps', not the Bike itself (you right), are settled too rich.
Sort of. Maybe your 10 year old bike needs a little less gas to run than originally, maybe you're tuning at altitude, or any one of 1000 things making the ECM compensate properly. EGO and AFV won't stay at 100 perfectly. They aren't supposed too. They are the adjustments the ECM uses to make the engine run the best it can.
By the way, using tunerpro, I could not find yet any map specifying targets AFR... anybody any idea where I should go to find it?
I don't know TunerPro. You put the AFR targets you want in MLV to have it produce the resulting map you want.
Anyway stock Bikes use in closed loop NB O2 so I think the only target EGO can aim is 14.7. Am I correct?
You can change the NB O2 voltages the ECM uses to change the point where it switches, if thats what you're asking? But you do want stoic at part throttle/cruise, anything else is a wasteful old wives tale. You can change AFR targets to modify the map for OL to get more gas when you really need it
If I post my Fuel maps, can anybody sure to have the right stock EEPROM for my bike tell me if they look the same?
There's so many different 'stock' tunes...
