[s-cars] RS2 MAF meter

[Cody Payne]

So Mike and Gang..are you saying that you do NOT need to purchase the RS2 MAF if you are going w/ the RS2 conversion (granted you are missing the safety screen now) but can equal the flow and ECU g/s readings of the RS2 by removing the screen on a stock MAF?

Less restriction from the stock MAF's screen vs., the RS2's plastic egg
crate, i.e. the RS2 will flow slightly more air at a given pressure.  But
then you can accomplish the same thing by pulling the screen(s) on your
stock MAF too.  Take out a pair of calipers & do the math.  The screen
physically occupies something  like @ 20% (I don't recall exactly any more)
maybe even more like 30% of the area inside the 72mm barrel.   Yes, those
little tiny wires do take up more space than you (well at least I anyway)
would think.

Speculation is that the two units generate "slightly" different, but so far
as I know, not quantified, electrical signals from the hot wire to the ECU.

Different chips seem to work with either MAF.  But, again speculation runs
rampant as to whether everything is working at "optimum" levels when you mix
& match.  You'll have to put burning bamboo splints under the nails of the
chip gurus, and even then I'm not sure you will get a reliable answer.
