MAF readings - how accurate?
« on: January 31, 2015, 05:30:45 pm »
I've had a search and nothing has come up!

I've cleaned up the MAF and seeing around 3g/s with VCDS on idle and when my foot is down in 3rd it goes upto 146g/s. On WOT it sits in the low-mid (mostly low) 140's. Using the 0.8 rule I should be around 160, can it be that far out or should they be pretty accurate? I'm wondering if I should replace it.

All this has started out as I believe I'm getting low MPG - even doing 40-50mph for 8 out of 10 miles a day seem to give me an average of 31mpg!
