Default Does the maf work during OL?

does the maf work during OL? i forget if it is disabled during OL?

the reason i ask is i dont have a custom os yet and i want to tune my car for some boost. I can't get my o2's to work so i am obviously running in OL.

my car is running really rich. is there another way to adjust this with out the maf, o2's and no custom os.

*edit* Is there a way for me to have my o2's plugged in but not have them adjust fuel for me? aka so i can run in CL with a maf but not have my "messed up" o2s correct any fueling?

Yes, MAF works in OL.

Yes, you can run in OLSD (ignores O2S's and MAF) and tune the VE table.

Running OL ignores the O2S's even when plugged in;

no, can't have CL when in OL (have one or the other); you want OL with MAF; or you could go OLSD.
