if you have a vr6 housing, put your stock sensor in that and scale the MAF table. That should give you enough overhead for now.
There is a program on these forums that will do it for you and write the changes right into your binary. You just specify the ID of your current MAF housing and the ID of your new MAF housing and it will patch your binary.

MAF sizing is already covered in the s4wiki tuning page, which you should already have read.

Yes several times, it's a lot to take in..
But I guess doing it the easy way isn't learning. Learn the trade before you learn the tricks of the trade sort of deal...

You speak as though it's 3 years ago where one could digest that in a single sitting. It's evolved quite drastically. |

Finally found the housing but I'm going to have to redo my turbo inlet pipe for the bigger maf. Going to be waiting a week or so for parts. I will update when I get it sorted out.

Hey, been a while but got around to putting the new intake on with the 3" housing.
I've just used to tool from mazer.gti to rescale the maf, I'll be writing it to the ecu tonight after work. I'll update with the results
Thanks

Oh man what a knob I am!
Forgot to checksum the file and now my Ecu is bricked, a friend of mine has a galleto 1260 but it's a clone. Any idea if it will work for boot mode?

Good News! Got it up and running, bad news, my maf scaling has cause some issues..
I've measured the internal diameter of my original maf housing which came out too 60mm but I wasn't able to measure the vr6 housing as it is in a really tight spot right now so I just did some searching and come up with it being 70mm, would anyone possibly confirm this for me? If I have to ill get at it and measure it myself..
anyways the car was driving like crap, low power when not in boost, bucking sometimes, rich codes, partial trim at -25%
Ive unplugged it for now until I can see whats going on, I'm sure its a scaling issue because if I remember correctly, when I had my original maf, the trims were good and my fueling wasn't so bad.
ill just throw some logs up, I'm going to have a look in the morning...

trying to comprehend what to do here, I need my fueling to match requested but I'm not sure what exactly is causing my issue. I'm reading the s4 wiki, looks like I will log ps_w vs actual boost and compare @ WOT...

Ive got 2 logs of ps_w vs boost, I also have the code descriptions -
P0103: MAF SENSOR SIGNAL TO HIGH --- According to the wiki I need to increase -KFMLDMX & MLMAX
P1127: SYSTEM TO RICH
I reset the dtcs once prior to doing the logs. If anyone has some time to help me on how MLHFM has to be fixed or even just confirm the issues I'm having, I'id appreciate it.
Edit: Also theres almost no power roughly below 3000rpm, I cant even hold 110kmh in 6th, unplug maf and its drivable again.
