I was just looking thru the different OS and in "2bar MAP - Speed Density" I see alot of MAF values still? Is it possible to run a MAF in that "2bar MAP - Speed Density" OS. I know if I run over 512gs it does no good, but its a low RPM motor that sees a high of about 400gs, I would like to have the added fueling options of that 2bar OS. This is a daily driver/tow vehicle with a single turbo, I would like to keep the MAF for the elevation changes and big temp changes. If I just change the OS to 2bar and leave my MAF is the computer going to read it and use it, or just be there giving useless numbers? I have researched and haven't found a yes or no answer, the threads turn into, "the MAF is useless after 512gs" and most seem to decide not to use it. Thanks for any info.
