Hi to all, I have read a lot of usefull stuff here and I wish soon I can learn more and more from you guys... So now I have a question... We made a K04 ibiza 1.8t with 440cc injectors and 3" maf... but Maf´s are failing to soon and Map seems to be very MAF sensitive... with Maf unplugged car runs perfect so I would like to dissable MAF trouble code, engine light, etc from the file. Just like a Cat delete. Can anyone help me figure this out?

Here is the Ori file.

Thanks!!

If you want to run MAFless go standalone. Pointless to use ME.

MAF is primary load input in ME7, but CLALM and CDTLM will help.

Hi ddillender!

Please explain, what you meant.

I meant it stirs up debate, and people argue. Much like the rs6x turbos on Audizone.

Mafless with motronic is a hot topic.

That's why I've asked you about this. I think to use MAFless as well but I don't know it's a good idea or not. I have tuning camshafts and GT28RS turbo.

^^ It is never a good idea to remove the primary load input to an ECU.

Mafless is not worth the effort because the car will never be able to run 100% correctly.  With that turbo, using a VR6 MAF will be easy for you to do.

I agreee with you, but many people disabled MAF. Also I can't undrestand how torque-model work without MAF...
Do you have the PN and spec for the VR6 MAF?

For what reason? Seems like all the people asking how to delete their MAF don't really know the answer other than "others are doing it", which isn't a good reason.

Exactly. It doesn't.

Many of the tuners that offered MAFless tunes are now no longer offering them because it crap and not worth the headaches.

That should tell you everything you need to know about wanting to go MAFless.

As for the MAF, google is your friend Smiley

But Mafless could have benefits.
Some motronics switch later to map running but when MAF don't detect correct mass flow it could make too much boost or/and run too lean. Sad
Maybe not all motronics.
I'm there no expert - but that is the only reasons I know.
Maybe also a reason want to sell a aftermarket ECM.

The ME7's that have MAF don't have a MAP sensor, very simple.
Only a charge pressure sensor before the throttle plate, which is completely useless for air charge calculation except for WOT.

It's maybe call T Map sensor but about the complete functions I have no knowledge.
I only know engine break downs because of damaged MAF sensors. Sad
Something with the generation of the mass flow.
But when everything is fine - it seems to be better.
