if you have the injectors set up right to begin with, that isnt an issue. especially at idle.
the VE/MAF values meter the fuel, not determine injector timing. if you argue that the pulse width increases as rpm goes up, well yes that is true, but also, more fuel is being added after the exhaust valve is closed so less is being lost in that action to begin with. so changing the timing at idle will affect low rpm drivability and power to begin with.
PE/OLFA really only matter in the higher RPM's where the injectors are firing more than they arent anyways.
