That's being kind. There are two primary reasons people run "MAFless"
1) they're too stupid or lazy to properly calibrate a load based ECU to handle pressures it was never designed for
2) they've heard "MAFless" is "faster" from those in category 1, who can't get a load based ECU to run right w/o ditching the MAF and forcing the ECU to run alpha-n (limp home mode)
https://www.m5board.com/threads/alpha-n-explained.531905/I've read this interesting write up regarding alpha-n. I think i get the idea.
I've also read s4 ME7 tuning wiki, if i understand correctly ME7 does have a table with values to use when for whatever reason MAF fails or is unplugged. So using this its running on assumptions for the most part if I'm correct.
As for now, I'll have to get myself a MAF sensor and i think I'll resort to an OEM diverter valve for the time being. As I've read a BOV won't work.
Another question; could it be possible my setup interferes with lambda control in any way? Bin is also posted in the thread if anyone would like to have a look. Returning code is P0130, wiring has been checked and sensor is fresh and OEM.
The reason I'm asking is because i suspect it might be either due perhaps some bad changes in the BIN. Or the way the car operates right now. If it can provide helpful info i can include a log aswell.
Thanks for your time!
