Example DFI maps.

[Matt Beaubien]

Hi all,

I'm helping a fried dyno his Ford 302 c/w Vortec R-trim, intercooler, SVO
heads etc.  He bought a DFI map from some guy with a "similar" combination
that has turned out to be way off. For instance, he had 10% fuel enrichment
from 150F on up...  In addition, it was so rich at an idle/startup, the IAC
couldn't supply enough air and ran like crap.  Taking 20% fuel away from it
everywhere helped a bunch, but still needs some fine tuning.  At an 1100 RPM
idle, the PW is ~1.9ms but seems to work ok for the big cam (~250 at .050"). 

I'm interested in general trends of constant map vs RPM, and map vs constant
RPM.  For a given MAP value, the PW should follow the torque curve, correct?
How much should the PW go up for an increase in MAP?

If anyone has any sample DFI maps they've created, I'd be very interested in
taking a look at them.  If the engine is blown (as in artificially
aspirated), so much the better ;-).

Thanks.
