newb question
 
I've been looking at my efilive COS3 tune and it looks like my car runs Open Loop all the time by the way the activation tempatures are sent....

my question is can i run OL and still use the power enrichment tables?

right now my PE is set to 11.7

Better question: Why would you want to continue to use the low resolution PE table? The whole benefit of going to COS3 is B3647, Commanded fuel Vs. RPM vice ECT which is what you get in a stock OS. Think about it, instead of just one value per rpm step, in B3647 you essentially get 3-4 WOT steps based on MAP 85-100. And since the pcm is sampling in adjacent cells of the active cell you get more control.

i saw that you can also enable you PE to come in when ever you want... right now i have my PE set to come in at 130map and i have my Comm. fuel Vs. Rpm at 14.7 except for hte last two colums and the step to 13 and 12.3.... then PE is 11.7

i was just wondering if this will work together or not...
