    Default How can I calculate the maf sensor

    I'm a noob and put an aftermarket intake on my truck (2018 Colorado 2.8 duramax.) I'm trying to learn slow but every strategy I've seen to calabrate isn't working for me because they're all on different software and idk how to translate that to efilive. Any help would be appreciated thank you.

    I am assuming you have a MAF voltage calibration table? As well as MAF voltage PID. You will need to apply "known" rpm and boost values in a way to make that table accurate again. If you create a curve on excel of the old table, the new curve will have the same shape, so you can do a fair amount of interpolation. This may involve putting the original intake back on and logging. One shortcut is using a ratio of your 2 different cross sectional areas, and apply the resulting scaling "factor" to your table values.
