Scaling MAF affect PE?

yea, don't copy the DIV/0 because there's nothing there. so just copy the range starting with valid numbers, and paste it to the corresponding values in HPT editor.
Does anyone know how to make a conditional in Excel that would not print anything if it gets the DIV/0 error? this way people wouldn't try to write over their stock numbers.

Hey RedHardSupra just FYI I was able to get 3 MAF values to calculate over the 10K mark. Not that it really means anything, but......
I forgot I had it in 1st instead of drive and hit my REV limiter at 6500 RPM and I got the 10K+ values after like 6100RPM Give or Take.
Also I applied the tune back to the PCM but haven't been for a drive yet sense its late; but it did fire right up and idled extremly well. Thanks again!

Yea, I got one doing 138mph once 
On the beginning I was worried what am I gonna do for the values I don't have calibration for. Then i'm thinking, if I never got a single value for these ranges, then it will never need them again either, right? I hope i'm right, but just in case, I used the points I did get empirically and built a 3rd degree polynomial out of it and used that to create the values I was missing. You might wanna try that if you want the full custom calibration.
Have you compared dynair vs maf before and after the calibration? they're supposed to be closer, i was just wondering how much closer they get for people.

i'm not an excel guru, i just know how to use google well
besides, the way the transpose function i used for the final calibration works, is an array formula. you don't enter one formula and then paste it over to a bunch of ther values, you actually first select a bunch of values, THEN you enter the array formula. so basically i can't do something to the effect of 'IF (ERROR!=0) THEN StockMAF[freq]'. So just use your brains and copy the good range, it will do you good to verify the values and such. Noone ever died of double checking
