Driving with MAF unplugged

[csre9]

There is a new guy in my town and he drives with his MAF unplugged for the sound between shifts..

He says it wont hurt the car but then again he said he runs a 200 shot nitrous at the track...LOL

How long can you drive with it unplugged and not hurt anything?

[espo4442]

unplugged for the sound? he must have a bov which is why he has the maf unplugged, either way unmetered air is not a good thing. he sounds like a dumbass do not take any advice from him

No no, unlatch the silver hooks to the left of the MAF and drive it for say a second gear pull and let off at 4k, it then sounds like you have an intake and upgraded dv's.(Thats why he drives with it unplugged)

This guy said it wasn't any harm driving it for extended periods of time..I was just curious to the truth and what it would affect so next time I see him I can educate his dumb ass so he doesn't say stupidity.

it sounds like he unplugged the MAF housing from stock box, opposed to unhooking the sensor. Making a Ram Intake without a filter.

I would only unhook the sensor unless i popped a ic charge hose and had to get home in jiffy.

No you can run with the MAF unplugged (the sensor), or actually with no MAF in the system at all. You have a MAP sensor, which will allow you to run 1) a BOV 2) MAFless is so desired. Will you get a code, yes. Will your car run normally yes.

is there any way to code it out?

what would be the benefits of running MAFless vs a MAF?

Yes, but only Unitronic will do so. I don't believe Chriss Tapp/Eurodyne has a maffless S4 tune. One of you gals should step up and have him write you a custom file to pave the way with 2 options.

I have a 2001.5 A4 running Mafless, N75, N249, SAP and 2nd 02 CEL delete (100% Custom Unitronic tune).

now why would i do that, i'm just asking questions for the sake of learning, i'm happy with my stage 3 with a MAF, and prefer the car not having a ricer queef

[csre9]

thanks, cant wait to see him and his 200 shot he said he have...
BTW he also spins tires in third..

The list goes on..

It was unbelievable.

I'm going to see if he will join AZ so he can learn something.

I run a Synapse BOV it doesn't make a queef sound like when we lock our doors It's the most simple BOV possible and only has the sound of the air venting out. Running MAFless is a matter of preference for some. In my case it was one less thing to deal with, check and replace frequently. MAF and MAP essentially provide the ECU with the same information to allow proper AFR.



Not running a MAF primarily is done for ease of intake track, you can run nothing but a screen or just a filter if you want like I do.

yes you can code it out, you can code out any sensor you want,

Only problem with running mafless is it gets worse gas millage

[Rajan147]

the horns on these cars are embarrassing. I dont know why audi cant give it a meatier horn. Anyway, thanks for the info. Its good to know what options or setups people are running.

[bassed]

yes you can code it out, you can code out any sensor you want,

No you can't code out anything you want, while you can write a lot out you can't write out anything and everything, if this was true ME-7 would have alot more being done and frankly able to run fully integrated ECU tuning on the fly. Mafless doesn't get any different mileage at all, the issues had are in winter with cold startups when running mafless. The car takes a tad longer to get an accurate absolute pressure, basically drive it for 5 miles and warm up and all will be fine.

Are you running mafless?

[2001S4NY]

not yet but believe me i will on a K03 car probably also

I ran my 1 ko3s that way for a month, my 2860rs that way for 6 months and now my S256 with a mafless tune. I never had anything other than 1 code indicating the maf was unplugged when not running a mafless file.

you talking about your tune on a A4 not a S4. So you did have a CEL for a Open MAF sensor while running mafless? any ABS/EPC/ESP lights or it was all coded out

It doesn't matter if it's an A4 or an S4 as long as it has a MAP, you can run with the MAF sensor unplugged. Will you throw codes for it being unplugged? Yes. I don't have ESP so no codes. I didn't have any ABS codes from this at all. Others may have or have had, but not myself.

My tune is presently the Uni custom tune mentioned above with all written out so I never have codes and have not for the 6 months I've been running this custom tune.

Nope he disconnected the maf sensor.

[Rajan147]

Nope he disconnected the maf sensor.

sounds more like he removed it along with the housing. No hooks on the housing just 2 notches where the intake box hooks insert, the other end is in the accordian tube.

Disconnecting the maf sensor would mean unscrewing it from the housing or unplugging it.

This is here nor there as the written word can be interpreted many ways.

One thing we can agree on is that he occasionally runs it mafless.

[VR4-S4]

Why then wouldn't my car run when the accordion hose came off the y-pipe? It acted just like any MAF sensored car.

[ama]

i know this is like dead thread, Will your esp actually work when it gets coded? Or do they just turn the error light off at the cluster. I mean im running no maf, and my abs and esp doesnt work. Anyone know who can do this for me?
