Hey Joe,

>(ftp://efi332.eng.ohio-state.edu/inside).
Thanks for posting that information, though its in "/incoming" not
"/inside" <Grin>
The sensor docs you put up there are the same one I have with my 3.8L FWD
engine, to be grafted to the 4.1L RWD engine. Cool - thank you!

I have an o-scope, but definately not a manometer. The more I've been
thinking about it, bypassing the MAF would be best if the whole assembly is
moved into a larger housing, including the existing housing, thus ensuring
the airflow that normally goes through it, won't flow around the sensor and
heating wire - with the existing housing removed, I can see air not flowing
overly straight, unless one makes vanes or basically reconstruct what comes
with the MAF.
Makes a lot of sense now !!!
