This MAF-less tune is only for 2000+ engines, correct?

edit-
just read the top where it says 1998-2006.... how do you run a MAF-less tune on an AEB engine since we don't have a MAP?

Well if you wanted the setup we can get the correct Eurodyne software for your car.

Wrong and now he is going to need to correct his post once again. Maf-less can only be done on cars with a wide band 02 sensor and doesn't have anothing to do with the map sensor. The 2000 ATW might have a map sensor but it has a narrow band 02. So its only the 2001+ that can run mafless tunes.

Wrong and now your going to have to edit your post. Sean ran MAFless for like 2 years

The client already had an ER Comp intercooler so we didn't provide one.

But if you wanted the complete package the intercooler we use custom FMIC using a Bell 24x6x2.25 bar & plate core and all aluminum plumbing

Cost of the all the goodies installed is $6000USD

Anyone can RUN mafless Clint, doesn't mean the car will run perfect. Only car that cant run mafless is a Tiptronic.[:p]

A narrow band tune does not have a set AFR spec that the ecu tries to hit. This means the car runs at WOT using the fuel map and uses the MAF to adjust fueling for the amount of air coming in. If you remove the maf the ECU has nothing to help adjust the fuel used.


There is a huge difference between running Mafless and tuned for Mafless. [>_<] This is why none of the tuners offer a "mafless" tune for the pre 2001 A4's. Believe me I have asked, even asked some if they would be willing to tuen the car using the 0-5 volt map sensor wired up to help adjust fueling during WOT. Thats when I decided to ditch the narrow band ecu and went SEM 4 years ago.


Let me guess why Sean went SEM. LOL

Interested in some more information on the tubi manifold. Do you have any pics, and do you sell it individually?

We will sell the manifold and downpipe as a combination unless you plan to custom make your own downpipe.

because Unitronic had shitty support. I could do standalone for the same reason. Its annoying having to log and send your ECU back causing your car to be down
