OL MAF scaling too off? :(
hello people!
need help. scaling the maf first time on 02 jdm wrx. wastegate is set to 0 not to boost more then wastegate spring loaded boost. (about 0.6 bar) mods are: tdo5 16G syms EL headers with uppipe; zerosports turboback without cats; k&n drop in filter; silencer delete; engine block ventilation deletes (goes to atmosphere); tgv deletes. I'm getting little spike of difference in 2.4 v area, after it matches OE scaling until 3v, after maf scaling goes off step by step and reaches 25% at about 4.3v. I have big quantity of data, 5 wot pulls OE front O2 is removed, running constant OL. wideband is located in downpipe, after turbo on downstime (AEM digitalbla bla...) I was not able to put table here, please take those values to build table and see if that is possible OE scaling 0.9375 0.976562 1.01562 1.05469 1.09375 1.13281 1.17187 1.21094 1.25 1.28906 1.32812 1.36719 1.40625 1.48437 1.5625 1.64062 1.71875 1.79687 1.875 1.95312 2.03125 2.10937 2.1875 2.26562 2.34375 2.42187 2.53906 2.65625 2.77344 2.89062 3.00781 3.125 3.24219 3.35937 3.47656 3.59375 3.71094 3.82812 3.94531 4.0625 4.17969 4.29687 4.41406 4.49219 4.57031 4.60937 4.64844 4.6875 1.16272 1.34125 1.53809 1.74866 1.98212 2.24762 2.54517 2.87476 3.22266 3.60718 4.01459 4.45404 4.94843 5.97382 7.13654 8.43658 9.84192 11.4395 13.179 15.0925 17.2852 19.7433 22.4991 25.5844 28.9261 32.4692 38.3331 44.9295 52.1988 60.0723 68.5684 77.6825 87.561 98.3688 110.078 122.694 136.189 150.673 166.2 182.835 200.638 219.695 240.024 254.214 269.087 276.814 284.697 292.735 suggested scaling using OLMAFTOOL and AIRBOY's spreadsheets: 0.9375 0.976562 1.01562 1.05469 1.09375 1.13281 1.17187 1.21094 1.25 1.28906 1.32812 1.36719 1.40625 1.48437 1.5625 1.64062 1.71875 1.79687 1.875 1.95312 2.03125 2.10937 2.1875 2.26562 2.34375 2.42187 2.53906 2.65625 2.77344 2.89062 3.00781 3.125 3.24219 3.35937 3.47656 3.59375 3.71094 3.82812 3.94531 4.0625 4.17969 4.29687 4.41406 4.49219 4.57031 4.60937 4.64844 4.6875 1.16272 1.34125 1.53809 1.74866 1.98212 2.24762 2.54517 2.87476 3.22266 3.60718 4.01459 4.45404 4.94843 5.97382 7.13654 8.43658 9.84192 11.4395 13.179 15.0925 17.2852 19.7433 22.4991 25.5844 28.9261 37.94137139 40.80053599 44.44926443 50.78347408 58.13621233 65.66727107 73.34720582 80.43474963 84.40344893 90.9334722 96.10247599 102.2089868 113.130822 125.9815415 138.0381407 151.194979 219.695 240.024 254.214 269.087 276.814 284.697 292.735
