The short of it...
ALDA on turbo engine adjusts for more fuel under boost (needed to make more power) by sensing the boost pressure and richening up the IP
ALDA on non-turbo engine compenstates for altitude differences (same thing but with no boost)
And it is not a valve...its more of a variable source of mechanical movement per pressure units of air.
I presume it is a acronym but I am not familiar with its associated words.
Anyone?
