I have usually used the mass air to get the fuel where it needs to be. I once tried the modify air/fuel but it didn't seem to do anything.

Anyone care to share their experiences on tuning for part and WOT? I want to make part throttle as efficient as possible to maintain reasonable fuel economy while adjusting WOT for max power.

Thanks,

I don't mess with MAF talbes but everyones different. To adjust fuel use
% change air/fuel ratio vs cool temp at WOT
and
% change air / fuel ratio vs rpm at WOT

not sure on part throttle sorry

 

OK, when using the % to change AFR at WOT, does increasing the number richen and decreasing the number lean it out or is it just like an air fuel ratio where a lower number is richer and a higher number is leaner?

you have to use a formula to calculate the target AFR

vea Andrew
=(1-(# in temp table)+(# in the rpm table))/100)*14.7

the computer uses both tables to figure the target AFR

But to answer your question the higher the number the richer it gets.
And vise versa
