Supercharged Lincoln Continentals

Daniel,

The 3.8L V6 engine was used in the mid-sized cars (well, what *I* call
midsized), T-birds, Cougars, and FWD Continentals.  I thought the Taurus
had a 3.0 supercharged engine in the SHO and a 3.3L for the naturally
aspirated version.  Either way, I'm unclear if this engine made it into the
Taurus platform.

Well, the voltage of the MAF does max out with barely any boost, so your
theory might be on the money.

I cannot tell you what the timing is doing... but you make a lot of sense
here. Buick GN's do the same thing, retards timing when the knock sensors
or pressure sensors sense potential trouble.

ANd that would explain it "running like crap" for 60 miles when I upgraded
everything - so it was in fact learning its new environment.

Its been good to me for 3 years... and the only time I have performance
problems is when the boost exceeds 7psi, which is rare.  I've hit the
120MPH speed limitation at just about 7PSI so I think I just lucked out so
far.

Anyway, thanks for the information... its been very educational...
