i finished porting my stock MAF .. then i checked my car for any code
i found two codes
1-maf high input circuit
2 maf high input circuit
can any one help me what is this?
i really will appreciate .. thanks

 

Those sound like the MAF electronics are
putting out an overrange (high) output
frequency. MAF porting should mess you up
but in the other direction, and not to a code-
setting degree. Did you do this with the
electronics still in place? If so you might
have smegged one of the little sense
resistors?

All together now...

"ported MAF... Baaaddd".

 

i`ve done like what www.installuniversity.com says
i have another maf .. do u recommened to descren the maf?

 

reccomend a stock one. with screen.

installuniversity information is old, and that is the one mod i do not reccomend from that site. the rest is good information.

agreed if you have a4 dont port the maf. m6 maybe?

i have had a home ported, TR ends and 85mm maf and none of them help me... only hurt my times.

but not all cars are the same... if your running really rich then yeah ported unit might help only becuase it brings the a/f ratio closer to stock...

 

modifying a sensor to get the output you want is "ghetto tuning" plain and simple.

we have the technology, do it right

Amen to that.. leave the maf alone. The only thing you'll gain is headaches. The stock MAF will support more flow than you realize The 1-2hp gain from this mod is not worth the trouble.
