MAF adjustments for larger air flow
 

hi all, i'm sure this topic has been covered but i cannot seem to find the right information or the right direction for what i need....


i have a 2017 Toy86, finally got some definition files so i can modify my tuning.. so i've hit a halt. i'm trying to use the 3in pipe that came with the air box and kit, but the pipe throws CEL codes - P0171. as i've already increased the +/-, i've increased the values for the MAF scale to accommodate for the increase of g/s. i'm not certain that i've up-scaled enough, as i'm still getting codes.. i have another pipe that is currently in place in lue to the issue - a smaller pipe around the MAF to see the 2.5in air flow.. somehow, but works for now.

i've increased the values to the MAF scale around the same as the PerrinCAI 3in pipe, but still getting codes.

if anyone could steer me in the right way, i'd greatly appreciate any suggestions!

for reference, my trims are -10/10, the A/B = 10, B/C = 20, and C/D = 40..
