im trying to understand here you guys are saying that if you use a bigger mass air tube it won't work or do you mean bigger tube and sensor won't work
well i thank you for reading first and not starting a thread on the same subject.
but your MAf is designed to work with a certin amount of air. stay with me ill try and break it down but i have bad pun. so it can get all jumbled..
VVVV not real numbers just used to explaneVVVV
lets say you have an intake thats 50mm and the maf stuck in it. and at 70 degrees it will send your computer a "1" for amount of fuel to add. and ever 10 degrees is another +/-.05 to send to the computer. so if you idleing in 70 degree weather, the comp is getting a "1" idleing at 60 degrees its getting a "1.05" and 50 a "1.1" now every cm of throttle moved is another .05. sooooo idleing in 70 degrees and you give it a lil gas the comp gets "1.05" 60 deg. "1.15" ect ect
still with me
now if you get an intake thats 100mm and use a MAf thats for a 50MM as soon as you turn it on. theres so much air going thru it thinks its -20 deg out side . the maf starts sending a "2" (max) and theres still "to much" air and the comp is saying wtf and throwing a lean code
all that to say this.
if you get a bigger maf housing you have to let the comp know whats going on my reprograming it to say "hey this is now normal start at "2" for fuel and work up or down as needed"
now i got a K&N air intake system that gets rid of the air box uses a cone filter and is a more flowing design (ie no sharp bends ). but were the MAF goes is made to the same ID as stock so theres no confusion wiht the comp and the MAF. its just desinged in a way to prevent the disruption of the air flow. so more air can flow faster thur the same amount of space.
