Hi Everyone

I've been doing some reading on the forum regarding mafless setup on a the 1.8t's me 7.5 ECU, if one should unplug the MAF would the ECU just run of the values that it has supplied in that specific MAP? Also to my understanding if one goes mafless the ECU will only add fuel if to lean and not reduce fuel if its to rich?

Reason for my question is that i've got some mates running BT 1.8t's with mafless tune (unitronic) and would kind of like to build my file around the same concept. Would mafless be possible for my setup if we should DIY the map.

This would be for a s3 8l 1.8t me 7.5.

Cheers  Cheesy

Why do you want to run MAFless?

MAF-less is doable but I recommend against it.

@matchew - foad  Roll Eyes

Anyways my reason for the mafless questioning was South Africa's spares market is pretty over priced and parts like RS4's airflow meters are not easy to come by at all, so it is a option im considering and just wanted to get further input on exactly how it would work, done searches on NM but most thread have comments like Matchew in which are useless.

So order it online.
The insert is like 60 euros. Surely that's not worth busting your balls over?

One question here , I have car with GTX35 , 2 liter stroke and  700hp. I blow MAF every two runs.
Maf is located 65-80cm from turbo . MAf is RS4 insert in 100mm housing , for the moment I run mafless as I cant afford to buy this quantity of MAFs.


Just asking someone with same expirience ? Need to understand why Im blowing im them so fast ....
I know that I can order PROMaf or HPX .... just want to figure it out ....

Thanks ...

@matchew - foad  Roll Eyes

You should grow up.....

The MAF on a ME7 system that has a MAF is the MAIN load input, removing it is foolish.

Falling back on to TPS vs RPM - no thanks.

@RS-MAD

Not sure. I have used the RS4 MAF on a few GT35R and GTX35R cars with over 600 PS and never had any problems (of course at top end the MAF is maxed in stock housing...)
Maybe there is some sort of hard vibration going on there?

And yes, the right solution would be to get a Pro-M Pro-Tube.

Perhaps you are running maf without air filter?
If yes this is definitely the reason.

I do understand I could import one to south africa with additional customs and so forth but im just trying to get a better understanding on the mafless setup as all the topics under search give no actual information / answer.
