Ok, then could be vibration.

I have of course had some "dud" MAF's, that were bad from the start with voltage spikes, and then died quickly.
But I have some cars with >500 PS running them for close to 2 years now, and no problems.

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.

Of course I'm all for a maf setup, but from what I've seen, people unplug maf, and tune out any test/diognostics/dtc's that pop up. Then tune everything else to their needs. Not really as complicated as shops make it seem huh? (Removing of the dtc's anyway, tuning will probably be more of a pain....)

I've never done/plan to do it. But why would this be, if you would be so kind Rick?

Because the ECU is in limp mode, so the load signal to the ESP/ABS unit is screwed as well.

Shame some here talk like pros when in fact they're still n00bs.

If your referring to me sir than you would be correct. I am, and will probably always be able to be schooled from someone with more knowledge on here than I. From what I have learned from the only mafless file that I own, is what I posted earlier. I have no interest in a mafless setup, so I didn't bother to look any further. If you would like, I'll be happy to edit my above post with "limited experience with mafless?"

Lol. Well there's a great example of taking someone's text completely out of context on the internet! My apologies...

So who are you referencing then and what side of the mafless / anti mafless discussion do you land on?  I personally do not think mafless and me7 can ever go together with 100% fueling accuracy.  I also am a professional noob, so what now?

No one out side of Bosch is a true master of this stuff, the very nature of the ecu and the hundreds of different ways to make functions interact will always leave people guessing/testing.  If you are calling others noobs then how about you drop some knowledge on everyone.

transverse 1.8Ts running MAFless have no issues with ABS/brake bias, that's what I meant.

I'd love to hear a "pro" describe exactly why anybody would want to run Motronic in speed density.

Me too. MAF conversions FROM speed density are commonplace (in other vehicles). Why exactly would one want to (IMO) downgrade? Maybe I'm being narrow minded here, but removing the MAF from the fueling equation seems foolish, and likely to leave you with less precise tuning.

That being said, I would love to hear arguments to the contrary.

The thing is, it does not really run traditional speed-density when you remove the MAF.
It pretty much runs alpha-n with enhancements.
