Bruce,

Specifically looking for ....
1) Is PE enrichment dependent on RPM and Coolant Modifiers (similar to $32,
 $6E and $8D)?  Is it dependent on anything else that I should be aware 
of?
2) If so, what are the start and end addresses in the BIN for these arrays? 
 
3) Is the WOT PE AFR calculation with this mask the same as the WOT PE AFR 
calculation for the $32, $6E and $8D?

Basically, I am very skeptical about adding this mask to the program unless 
I am comfortable that I understand the data behind it (as any programmer). 
 I want to please the masses by adding it but I don't have the time or motivation 
to research the LT1 speed density system right now.  Plus, I don't own one 
of these engine management systems so I would rather gather this information 
from an individual who truly understands this system.

Tim
