Hello,

Anyone who have the MAF curve from an A6 4.2L V8.. (model 2000). I was in a bit hurry and bought a V8 MAF sensor.. But im not sure if this "sensor" has the same curve as my VR6 3.2 sensor. I changed sensor and got Fuel trims -22%.. Im suspecting that this sensor i a bit diffrent?  I also asume this sensor reads a broader area?

from memory i think they are the same as RS4 2.7T

Ok Ill check that out.. Thanks for that m8 !

Sorry its not g/s  its Kg/s

S6 4.2 MAF (one of them) is also the same (including output curve) as RS4

Graph the curve as a scatter plot, create a trend line and then show the formula for the trend line. Create a new row of all your voltage values, and then type the formula into the next row with voltage value cells subbed in for the x values.

Thanks I´ll give it a try 

In fact, i'll add a bit more info.

Jim, was it you that put up that HX35 032E file ages ago in the noob area? If so and if it's the one you're using it's slightly different to a stock read so the values are slightly out in places. Attached a pic to show the address if so as it's the end of the map/mlofs that lines it up as usual with these if using/building a def file? Have attached various 512x1 MLHFM's for V6 4motion/R32, they usually line up perfectly between variants - i.e. v6 4mo v v6 4mo, mk4 r32 v mk4 r32 etc as shown.

I've also added some bits which help to find it in white, the reverse-flow hfm5/MLOFS same data/values after the main MLHFM map in them all - the damos files for these are usually highly questionable in places, takes a lot of work to go through each map when building on a stock read so if you use one try the mlofs areas to line up then cross flash - should be spot on! Also if you are using a damos, there's a few with the voltage values re-scale by half which is why people struggle on their stock ones.

Hope it helps!
