Hi!

(English is not my native language)

I'm interested in using a raceline wideband harness on my ATW engine and test it without MAF and also test and open BOV.

I know I need the AWM ECU and the wideband sensor.

The problem is that I need to figure out how and what I need to change in the ECU software to make it all work.
Is that someone here that has that knowledge?

Also, are the WB-harness and bench-harness from Raceline any good?

I'm from Sweden and I do not know if Raceline ship their products worldwide.
If not, can I get the stuff elsewhere?

Anybody that have some more info about my questions? Maybe some pointers on which maps that needs to be modified to get all to work.

I can think it is pretty much stuff that needs to map different in the ECU so you can use only the MAP-sensor and remove the MAF.

I have recently read that you can also use a another MAF that are made to blow through.
But I can think you need to map a lot of things in the ECU to get it all to work good.

Hehe! Maybe BOVs, mafless and blow-trough MAF isn't so popular on this forum.

I can get that it is no good or precise solutions for an optimal running engine.

I have read about the HPX MAF-sensor that you can use as a blow-through.
And they have 512 points data-sheet on the website so you can calibrate it for Audis.

And the sensor is good for a lot of HP if you use the right dimension on the MAF-housing together with your hardware setup.

Nobody is answering because you really don't need any of that to make a car go fast.

Yes, I know that you can scale the bosch-sensor for bigger housing and get all to run good and high HP.

But I am curious about blow-through because you can make the plumbing for the air intake easier, neater. Especially if you have a big turbocharger and aftermarket exhaust manifold.
But all this is only some thoughts from my point of view.

What exactly are you needing help with?
