Question about WOT table in $8D bin

[timsiford at hushmail.com]

Bruce,

I don't think its as bad as what you are saying.  Please - hear me out. 
 I said that the calculation shows that I am running 10.16 AFR.  This was 
at 5600rpms and a coolant temp of 80deg C.  HOWEVER, the stock AUJP bin 
has a PE modifier of 7.8 at 4000rpms in WOT %Change in AFR vs RPM and a 
modifier of 22.7 in WOT %Change in AFR vs Coolant.  This results in a 10.22 
AFR.  

Now, I am NOT running 10.16 everywhere.  I just picked the highest point 
of the curve and reported that point.  I also picked the highest point of 
the AUJP curve and reported that.  Again, the formula I am using is the 
one previously supplied here on the list ....

( 1  -  (( RPM Mod  +  Coolant Mod )  /  100 )  *  14.7

I am not concerned about the fueling.  I am close to 128 at all points when 
driving.  I spent significant time on the VE curves.  The WOT %Change to 
AFR tables are modified from stock ... but, no so much in the levels but 
more as to the shape.  The MiniRam doesn't need as much fuel at 4000RPMs 
as compared to the TPI.  However, it does need more at 5600rpms.
