Question about maf hack.

[pitbull419]

So im doing all the free mods on my cousins car.
After I took out the maf to hack it i was wondering If I could cut out the divider in the lower "runner" I will post a pic of what im talking about.
Also why the hell cant I remove the upper honeycomb? I always wondered that.

Hes running a 16g and tubular header on stock boost.
Untill Tuesday, I have a surprize for him
He said hes hitting fuel cut, so i will be checking on that tomm.

There are alot of negative affects to "hacking" the MAF. Have you searched and read about them? There are better, safer ways to go about doing what the MAF hack does without the drawbacks.

 

[Johnny123]

what safer ways? and what kind of drawbacks??

Free mods.... Take it from a dsmer thats been around the block. If it doesnt cost money it isn't that good.

I am laying down 450 horse on pump gas with an untouched maf.

taking out the main honeycomb will make the air going through the MAF more "tubulent" and the meter will not get an accurate reading of how much is actually passing through it. Then, basicly your car's A/F's will be screwed and it will run like crap... there's honestly not much power to be had from many of the "free mods"

gutting the cat or a "test pipe", a good exhaust, K&N and a MBC is about the best low cost mods you can get

disclaimer.. i do not recomend gutting the cat, make a test pipe and then of course use it only on a closed course off of public roads where teh EPA and state police can't touch you for the use of it

Im not new to dsm's. i ran 11's on pump gas.
This is just the way i started with dsm i alwas did the free mods since car 1(i was 13)

zero97tsi- What drawbacks?

For starters read the bottom of the Vfaq for it

I can cause pretty negative problem with your A/F mix. The guy who wrote the vfaq experienced low speed drivability problem, pretty nasty ones it sounds like. If you search for maf hack on the forum most of the results will include negatives about the mod.

I don't own a 1g, so haven't tried it, so I don't pretend to be the definitive answer on it. Read up on it. Read the vfaq. If you want to go ahead and see if you can get away with it, go right ahead. But perhaps do it like the vfaq in a fashion where you can re-assemble it just in case. Some people have done it and it seems fine.

But, Oldman said it best in one of his posts in a maf hack thread

"Not feeling a problem doesn't mean it isn't there, do a log and see what happens."

Just because it may feel like its running fine, doesnt mean it is, which can be just as detrimental as something noticable wrong.

the whole reason i switched to a 2g MAF was the troubles i has with my hacked 1g. when you cut of that bottom section of the MAF, at idle you pull almost all you air through that section (since the sensor section has the honeycomb in it, it is more restrictive) so you have a rough ugly low rpm idle and rough low rpm driveabilty. you definetly should run a hacked MAF with wideband and some sort of fuel controller. hacked MAF's just give you funky driveabilty until you get a real good tune. look into a 2gMAF. they are easy to find, super simple to install and support upwards of 400hp. although my buddy ran his 50trim off a hacked 1gMAF and made great power and daily drove it. to each his own

I was not talking about cutting the entire bottom off.
Theres a divider that runs through the bottom.I wan to cut that out.
It splits the bottom in to two chambers.I want to cut it out so the bottom is one chamber

Yes, you can cut that out if you want to, but it will only make the drawbacks more noticeable if you do (as more air diverts that way)... hell, one person chopped away the entire bottom passage, just left a gaping hole to the intake pipe. Idled like utter crap.

I own a hacked, and an unhacked MAS so can compare them side by side. The hacked MAS gives slightly better top-end pull, but results in idle misfires, parking-speeds stalling, loss of bottom-end torque and drivability, and power is slightly 'erratic' at any given moment. Sometimes when your foot comes down it'll slam you back hard, other times it barely feels like it's moving.
The unhacked MAS delivers consistent, reliable performance. The power you make is far more usable, and feels stronger through the bottom and midranges, even if it tapers off a little more noticeably at the top (hits the 'wall' sooner, where torque drops off at around 6Krpm, instead of 6500, on a B16G). The car idles smoothly, and it behaves like any other street driven vehicle you might hop into for city-driving.

At least for me, sacrificing that slight top-end gain is worth it, making the car more fun to drive, and less of a 'strip queen' feeling.

^^^^^^^^^^
i second that one. these cars are so fun to drive. unlike a honda you don't really have to dip into those sacrifices for that tiny extra pull.
wise man once said "you get what you paid for" the hack MAF costs nothing see what i'm saying
