The power commander just add or substracts to the puls lenght that comes from the ecu. (it does not know the lenght of the pulses its getting in the first place),
On the 996 it uses the positive egde of injector opening for RPM measurement.
but it knows from dyno run / configuration/map that at a certain rpm and tps its adds or subtracts the opening time for the injector.
I Dont know the ecaxt logic, but it means it has to measure puls length, and on the next cycle/revolution do the adjustment.
Adjustment must be made on the revolution after the "measurement" is taken.
1000 rpm = ca 17 adjustments a sec
12000 rpm = ca 200 adjustments a sec
Someone correct me if I'm wrong !
If the bike was mapped at se level the it there should be no reason to add og substract when going to an other altitude, as the ECU compensates for this.
Higher altidue means lower oxygen in the air, the bike need less fuel to work 100%.
Power will always be down with lower oxygen in the air.
IF you add fuel, it will probably run to rich.
But it comes down to the trim values in the Ducati ECU if these are correct, and I azume they are(they have to done som reasearch one this)
