ok i am trying to figure out the right way to add fuel to the "% to change AFR vs rpm at wot" and the other that is ""% to change AFRvs cool. temp." also how do i richen up the open loop AFR vs coolant temp vs map?

Tuner@Straightline

With the tuner cat software for the LT1's, the PE adds the value of the "% to change AFR vs rpm at wot" and the "% to change AFRvs cool. temp". In simple terms, think of it as the "% to change AFR vs RPM at WOT" as being able to change the AFR per RPM, and the "%to change AFR vs Cool. Temp" as a global fuel adder for PE. Increasing the values of these tables addes more fuel.

now that brings me to my next question...how much of adjustment ,say +1.0, will make a difference on the AFR?

Tuner@Straightline

A 5% increase in the values should result in a change in AFR close to 5%. Need a wideband to be sure though.
