Well I have been running with this engine mod for maybe a month or so now. I have an Avant and it works just fine. I find that I do in fact get better gas mileage. Before I was getting 22mpg to and from work on 87 gas. Now I get 24 doing the same commute on 87 gas. I first thought I was just driving differently, but now that it has been several tanks full, I know the car is just getting better mileage.

As for power increase/feel...I can't say for sure. I bought my A6 because I wanted a wagon, not a sports car. I rarely floor my car or even accelerate all that quickly. So I am unable to say if my car has more/less power since I really don't know what it was capable of before the mod. My car is a hwy commuter/grocery getter, and I drive it that way.

By the way, there is a way to make the 2.8 tiptronic hold first. I myself don't know what it is though. All I know is that the previous owner did it to mine. In tip mode it will not shift to second until I hit redline....same as any other gear. Can't find the site for it yet. I'll keep looking for you.

Yup. I bought my avant for both. Skiing, hauling loads and people and going fairly quick while doing it. I also think the avant looks better than the sedan.

 

Ok so now I'm really confused. I found them...
00002 = stock
00012 = sport mode
00022 = holds 1st gear in tip mode
00032 = sport mode and holds 1st gear in tip mode

But mine is in stock mode yet still holds first gear in tip mode. Whats that about?

 

So I just took another test drive...two actually.

First I switched the tranny code to 00032. I wanted to be sure that it wasn't simply the transmission that was making the car seem slower. I noticed right away that it did indeed take less pressure to make the transmission shift to a lower gear which is what I wanted. I pretty much had to floor it before for it to change gears. As my tip mode had already held first gear I cannot comment on that.

The engine still seemed slow though. So I did another accelleration from a light then pulled over and swapped the engine code back to stock and did another accelleration from a standstill. Much better. I don't know why but it just feels much better and pulls a little harder when the last digit of the engine code is the number 2. (didn't think to write down the whole code).

yep for me accelation is much better it picks up bit more from stop and when I want to step on it goes.
and milege, definate change. increase in few miles.nomrally takes 1/4 tank of gas from driving to and from longisland to upstate yesterday after change didn't hit 1/4 mark.

I'm happy with it. so far no negative effect at all.

 

i just bought the vag com on ebay and will do that as soon as i get it

 

Let us know if you have any problems with setting it up on your laptop. Also i'd suggest recoding your central lock module so you can control your windows with your remote and etc. and you could recode your tranny to put it into sport mode or to have it hold gear untill redline.

I've put mine into sport and noted that shifts are not as smooth as before but, it makes up for it when you want to do some spirted driving. Also if anything at all, I've noticed an increase in gas milleage even tho i put the trans into sport mode.

 

hey Asianicestyles, do you have the code for sports mode for tip?
that I haven't done yet I like to do next.

 

Sure,on the 2.7 and other engines the codings seem to be diffrent but the stock coding for our engines should be "00000" just change it to 00010. 1 is sport 2 is hold gear until redline and 3 is to have sport mode and hold gear untill redline. Although I've only been able to recode mine to 1.

 

thanks man will give it a try tomorrow since it's a rainy day here in NY, rather test it in nice dry day
