Default MAF Table

Here are all of the MAF flow/freq values I have collected.
Tab-delmited txt, from Excel, you should be able to import
it easily enough.



MAF Type freq Hz 750 800 850 900 950 1000 1050 1100 1150 1200 1250 1300 1350 1400 1450 1500 1625 1750 1875 2000 2125 2250 2375 2500 2625 2750 2875 3000 3125 3250 3375 3500 3625 3750 3875 4000 4125 4250 4375 4500 4625 4750 4875 5000 5125 5250 5375 5500 5625 5750 5875 6000 6125 6250 6375 6500 6625 6750 6875 7000 7125 7250 7375 7500 7625 7750 7875 8000 8125 8250 8375 8500 8625 8750 8875 9000 9125 9250 9375 9500 9625 9750 9875 10000 10125 10250 10375 10500 10625 10750 10875 11000 11125 11250 11375 11500 11625 11750 11875 12000

You should bold the vehicle types so it will be a little easier to distinguish start and end

Is this what you have mapped out? Or is this what you have collected from different resources?

These are stock tables right? Here everyone...I took the liberty of putting these in an easier to read .xls file:

FYI: If you download my file I just added 2000 and 1999 Corvette MAF tables.

They are actual tables from PCMs.

Yeah, I did a bunch of digging around, asked people to
send me their tables, etc. - all look to be stock, from
the vehicles as noted. Have yet to come across any
actual high grade, proper flow calibration. But close
enough is good enough especially if you have the
wideband for your final calibration.

An interesting point of interest for you guys, the MAF flow for the C5s with the same MAFs is different in a way that has made me just switch to it for my latest tune. It is curved about 105% of the F-body's at the bottom gradully moving towards a little less than 100% at the end. It is probably more acurate for a setup with a lid, like most of us have. Much different than just scaling your whole MAF table by 105%.

This also explains why my VE table started high, went low, and then started to go up again. The MAF reading was too far off because of the lid. I thought I was doing it wrong...but I wasn't.
