Independent?.   I don't know if I'd say that.  They both are differnent way
of calculating the same thing, appropriate fueling.  On some applications
some of the scan tools, display MAP+MAF numbers for a application that only
runs one, of them.  I forget the application off hand, but was some of the
1227730 applications.
