N55 log parameter bounds

I'm sure I'm wording this incorrectly, but does anybody know where I can find a list of safe parameter bounds for the N55 platform?

What I'm trying to do is create a site similar to datazap, that will graphically display a users logged run along with analyzing the information and turning all those numbers into actionable data.

If i understand what you are asking, its not as cut and dry as you might think since the safe bounds for some parameters depend on other parameters, so there may not be an absolute threshold that's easy to code.

Some parameters might be easy - i.e., those that the log gives both target and actual like boost and HPFP. So it would be fairly easy to flag if you have significant boost deviation or HPFP pressure dips. Others would be more complicated.

Reading my thread on datalogging is probably a starting point: https://f30.bimmerpost.com/forums/sh....php?t=1732327

Awesome, thank you. Yeah I figured it will definitely be tricky figuring out some of those parameters, but I plan to start with the basics. Appreciate the response!!

too many variables.. you'll have to account for different mods, different variations of mods and ots, custom tunes etc.. you'll never be able to figure out a good afr range because of this.. where timing should be etc.

if you aren't familiar with all of this info,eating you aren't a professional tuner but have hundreds of hours of time to do it, you may wanna not bother trying

Sounds like a good challenge! Gotta learn somehow.
