Busa EFI Help Needed

[OB_DanaT]

Does anyone know how the Busa's EFI compensates for altitude? I am curious if it has a sensor that would be the equivalent to a cars 'manifold prssure sensor'?

I am asking this question as I am getting a pipe in in the next few day (maybe today) and would like to know if my Busa has already copmpensated for altitude (running leaner) or if it just runs in a rich condition here all the time. If it runs rich all the time there may be no need to fatten it up.

How does the PCII compensate (or work) with the Busa EFI settings for high altitude?

Would specific maps need to be made for the PCII for high altitude operation?

I don't have a PCII yet; I think that the bike may already be lean so I will see what it does with the pipe and go from there.

Thanks

dana, yes it has an atmospheric pressure sensor (measures barometric pressure) (altitude) it is located on the right side frame just under the gas tank. altitude is compensated for by the ecm. it changes injector duration , to a certain extent. ref. suzuki manual.
