 My question is about
the asynchronous BTW handles in three tables. One table is for Maximum
and one is for Minimum and still one is for RPM.



I didn't catch this part of the question originally.  "handles" = constants?  Singular values 

as opposed to a table of values?



There's two possibilities which I can think of.  One is that these values work with an 

"asynchronous pulse accumulator" which can be read about in the turbo P4 document.  The 

second is that these constants determine when synchronous fueling is abandoned for 

Asynch fueling due to physical limitations imposed by the injectors.  



Have you seen a change by adjusting these values?  If they affect the asynch accumulator, you may not.  If 

they change fueling mode then you'll hear the injector pulsing change as you set min and max value as 

well as rpm to fairly large numbers.
