Hey!
I've done a fair bit of reading now and I think I have an Idea what to do... But I'd like to check before I go in and mess things up!!

This is what's happened.. I have an Audi A3 1.8T 20v 2003 ME7.1. It's stage 2 tuned and was running great up to the point that the exhaust fabricator shorted out my rear O2 sensor (I think that's what happened). It's caused a problem with my ECU to the point that I have had to get another one. I bought it off Ebay and it was sold as Immo off.
It starts the car no problem but runs like a bag of crap.. I put my Stage 2 map on it from my original ECU but the car won't start? So I assume he's done Immo off via the file.. Rather than on the EEPROM.

Now my 2 questions are...

1. Can somebody Immo off my tuned file that attached here? If so will save me some work benching both ECU's.

2. If not can I just make a back up of the original ECU (Clone it) then write it to the new ECU without any issues? Will this transfer over the original Immo data too?

Sorry for what might seem like newb questions but in an hour and a half I couldn't find my answer..  ::)

Any help would be greatly appreciated.

Many thanks,

We're the two ECUs identical part numbers?

Where is the stage 2 tune from?

No, they are not identical part numbers but the new ECU worked with the map that was supplied on it. I was told that with the Immo off solution it would work no issues..

The Stage 2 file was bought from a well known tuning company in the UK. I flashed the file on myself with a genuine Kess2. The stage 2 file works 100% perfectly on the hardware.

Many thanks.

your file has errors in it .

In what way? The file I posted ran perfectly on the car.. Just won't start the car with the new ECU. :(

I'm not worried about the file I posted TBH..

As number 2 of my questions.. Can I just take the EEPROM read from the broken ECU and write it to the new ECU via boot mode without issues? Or is it possible to clone the ECU via Ktag?

Thanks again.

first off the file you posted is straight crap. missing checksum blocks and over 7 errors. second its me7.5 not me7.1 3rd yes you can clne it with ktag if the ecu is going in the same car if not the eepeom data wont be right and youll get stuck with a nostart condition. i have immo off solution in flash that avoids having to to open the ecu if you need message me.

attached is a immo off eeprom for me7.5 cks good and ready to write

Edit***

The hardware numbers are a direct match..!

Marty, Chers for the reply.. I've sent you a private message..

The checksums are not an issue... My Kess will correct checksums! I write file and it askes me for original too, then it will correct for me. My bad with the ME7.5 I've just checked and indeed I'm wrong!  :-[

heres all the maps changed in your file i made a map pack of all of them

Thank you Marty!  8)

You're a good egg!

How much did you pay for this "tune"?

Far too much by the sounds of it.  :'(

Would you say it's aggressive or just half hearted?

Even paying for it is too much.
It isn't even quarter hearted.
It's just a simple eBay tune.

Boost cranked to 11
Irrelevant fuelling
Overboost protection & diagnosis disabled
Arbitrary addition to timing
Nonsensical changes in IOP & IRL

Sure, it'll run like hell.
But it'll kill itself doing it.

what setup do you have on the car?

Wow  :o

I'm really shocked.. Truly I am.

The car has a K03s that's brand new, 3" MAF, FMIC, Cold air feed off a cone filter, 3" decat and full 3" system. Was told it should be running 1.5bar max boost.

I don't know my VAG's at all.. I don't know what is high boost TBH..

Thanks for the replys

It'll do 1.5 bar, but it'll kill the turbo.

My advice to you is;

Delete this "stage 2 tune" and don't look back.
Pay a real tuner to make you a proper tune.

Alternatively, use the free resources on this forum and make a tune yourself.
Even you could probably make a better file than this in a relatively short time.

I'm not just ripping on you/this "tune" for some sense of satisfaction.
I'm stating the facts, and helping you understand how bad this "tune" is.

If I told you the company that sold me this tune you'd seriously be shocked.. Ok, for now it will have to get me about. BUT I taken all of what you have said on board.. I will look into sourcing another..

I will use the map pack that was kindly uploaded on here and look to improve upon the file. I will use all the info I can on here to build a better file...

I can't thank you all enough for your help.. I'll stick around on here!

You don't just slap on a 3" MAF and run tune designed for the stock MAF.

While this tune isn't the best, it's not as terrible as others are leading on.  Yes, some protections are disabled or numbed, but LDRXN isn't maxed like it sounded it would be.  This file won't be good for 1.5 bar though, probably more like 1.2.

I would be concerned of a "well known/respected tuner" that would sling this shit around though.  Especially a file with 7 bad checksums.  You were most certainly duped.

I bought the car with the MAF on already, the only thing I have done is put a full 3” cat back on it.. The car ran really badly when I bought it. I’m am aware you don’t just slap stuff on.. The previous owner removed so much, evap, n112, n149 and a lot more.. I don’t know why, I’m out of my depth with VAG.. I’m normally a Honda man..
As you can imagine I called this company told them my Hardware and what has been removed and that map is what I was sent..

I need the car running for now but I’m going to use this a lesson learnt. The problem is the company is a reputable company and I’d never have expected them pass me a file like this. Until I came on here I was none the wiser..

As soon as the car is running I’ll do some data logs.

I saw some changes in MLHFM, so file might be compatible with 3" maf :)

Are we talking ARP?

The MAF is scaled for a 225 either TT or VR6 I’ve been told. Before the Isle was really really bad. Now it has no issues on idle at all.

That’s not the company but I’m not one for public shaming unless I talk to them first. As I’ve not done that I’m going to bite my tongue and refrain from the slating.. For what it’s worth the file cost me £90. Which is on the high end for a file service but I thought “it’s worth paying for quality”  :-[

Hello, Im doing some research and i see this file, I'm wondering if this can be written into any ecu (ME7.5) to delete immo? And if so where in winOls or which file is the file to be overwritten? Ive been on ecuedit and nefmoto 14 plus hours this week. I havent found one real straight answer. Thank you for any help you may give me.
