I have an a4 1.8t quattro -00 with manual gearbox.
The ECU is a motronic 7.5, 4B0 906 018 CG.

Can I in some way use an original Audi 180bhp file in my ECU. Or maybe copy/transfer the 180bhp specific maps into my 150bhp file?

As I understand, the difference between 1.8t (150bhp) and the 1.8ts (180 bhp) is only the turbocharger itself, the Ts has a k03s and the 1.8t have k03.
Or are there more differences that I have missed?

If I can, which years of the TS model should I look for, and what numbers should the TS ecu have?

The only A4 1.8TS 180hp that I'm aware of is the 98-99 model year, which was M3.2...

Strange, I have seen a4 1.8ts quattro -00 -01.
Maybe you only find them in Europe.

Looks like a 7.5 ecu.

If so, just copy the different tables over....

4B0906018CG is a regular 110kW/150 PS 1.8T, I've done about 15 of them, first one back in 2004.

Yeah, the CG is a 150ps ECU. That's what I got in my car.

What engine codes does the TS models have?
What are the hardware differences (engine) between a 150ps 1.8t and the 180ps 1.8ts?

Hi, 1.8T a4, passat,and a6 with 180 hp is motronic M 3.8.2  and engine code is AJL.A4's ME7.5 motronic with 163HP eng. code BFB and 193HP with eng code BEX,but they got 8E0 ecu's.Try to tune your own ecu and with a good job you can see aprox plus 20%-30% hp increase with stock hardware.   

Ok, thanks for the info!

Why I asked about using a OEM 180ps file, are because I'm lazy and was curious about an shortcut to a little more "oomph" in my car.
And also because I trust more in the OEM "tune" instead of all the stage 1 tunes out there from both tuning company's and self proclaimed expert tuners.

I have read about small tuning company's that copies each others stage 1 tunes etc.
And when people look into the files it reveals that the tunes is no good anyway.

Sadly I don't have the knowledge yet to tune my ECU completely from scratch.

So, I can count that it is no good/impossible to use the 8E0 file in my ECU and get it to work fine? Not even try to copy the specific maps?

No chance

Too bad.

Are the any other ECU's from the ATW engine code that I can use as spare/backup box for my car? Maybe even from VW Passat?

do the wideband conversion!! that will give you a lot more options when it comes to software versions... just need wideband o2 and vvt delete

Yes, a wideband conversion is one thing I really want to do. I have seen PnP wideband harnesses you can buy.

But what do you mean with a lot more options when it comes to software, can you give me some examples?

Do I really need to do a vvt delete?
Can't I just use the vvt solenoid on my awt cylinderhead?

The ecu software must have the vvt function, but I get it when I use the awm ecu, right?
Because I think I have read that you need to use an awm ecu together with the wideband lamda harness that you can buy.

vvt would work, awm ecu would be the most common ecu to swap.....but awp aww will work along with some other wideband engine codes ... auto or manual... its all about the file thats loaded to the ecu...the ecu would need to be immo offed... google narrowband to wideband... you dont need to buy a harness you can make it all yourself there is a few how tos

I have been to the junkyard now and scavenged two spare ecu boxes, both from the awt engine. One from an vw Passat and the other was from an Audi a4 -2001

One of the ECU's "box number" ended with an R instead of CG as the other box and the box I have in my car. Is it something special or different with the R box?

Which years and models etc. have the awm, aww and awp engine codes?

aww is in 2001 golf / jetta awp is 2002-2004 awm is late 2001-2002 a4 and 2002-2003 passat. Google is your friend too dont forget ;)

Does somebody make bench flashing harness/tool and PnP wideband harness on this forum?

Because I am not that savvy when it comes to soldering and the electrical stuff.

My car has the same awt motor, ecu ends in R. The etka thingie lists cg or r ecus, i don't know what the difference would be? Possibly awd's got the r version? Just a guess.

Also, from what I've looked up and tried to make sense of the awt is wideband already?

I've never found a great deal of info on the awt

I got quattro, and my ECU box is a CG.
I don't think awt is wideband, but I can be wrong.

Is it some easy way I can check if the engine uses wideband lambda?

wideband ecu have 29F800BB and narrow band 29F400BB .
in wideband ecu measure group 31 give lambda value and in naorrowband it give lambda sensor voltage

You legend, thank you

It seems it is hard to find awm ECU's here in Sweden.

How about aww and awp ECU's, can I use them in my A4 1.8tq -01 if wanna go wideband lambda?

What ECU's are an direct "fit" for my engine that uses the 018CG ECU?

edit....

?

I tried to read my ecu in my car using the narrowband memory layout, but that didn't work.
So I tested the wideband memory layout and   it was successful.

post it up atw is narrowband and btw not all 800bb chips are wideband.. m box s4 prime example

I have posted my BIN in the Original ECU section.

oh you know what I was talking about ATW (USDM) not AWT engine code... Im snot sure to be honest... a easy way to find out for sure is count how my wires go to the first o2 sensor...
Sorry for the confusion

I checked my lambda with VAG-COM an it seems to show lambda values and not volt.
So I do have wideband lambda on my car.

The values when I checked was:

Lambda actual value - 1.000
Lambda spec value - 0.766

That must mean wideband lambda values, right?

-01 AWT with CG ECU is wideband.

Yes, thank you!
At first I didn't thought that it was wideband, and only awm was wideband.

Then I read my ecu and noticed that I needed to use the wideband memory layout for reading. And the BIN file was 1024kb and not 512kb like a narrowband file.


But I read a thread today and in the thread it says that you can read the ecu wrong and get a 1024kb BIN file with two duplicate 512kb narrowband data in it.
How can I check my BIN and see if it is something wrong with it?

Can I use other BIN's on my 1.8t 018CG box?
Which ones?

Could be useful, cause other BIN's may have very good definitions done already.

I am also thinking about compare original 180ps BIN's to my original ecu file, to try learn and understand the different values in the maps when it comes to different horsepower gains and so on.
Some tips on good BIN's to start with?

Could the AWT engine also have VVT?
are there simple ways to see that on the engine or using vag-com?

I'm starting to wonder if I have an 058 or 06a block.

I'm pretty sure AWM is 06a block, VVT and wideband.

But I'm starting to get confused about all the small changes between engine codes. Especially my engine code. (AWT)
