target afr

still i have question about the afr target i am sport bikes tuner i do ecu reflash in my case if i read the afr from the dyno screen from 10000rpm to 14000 13.1 i will make it richer i will go to 12.7 to 12.8 what target means

your target afr should match your dyno afr if your target is 12.8 you need to tune the volumetric efficiency table to get it close.

once you get the ve table tuned right you can change the target without retuning
