Hey guys,

Im new to all this and getting a crash course.

My problem is, i had a friend flash my 551al with a stage 2 tune. Have no idea who wrote it. When it finished the car wouldnt start. He gave up trying to fix it. When trying to rewrite it said it needed to finish to process.

So i started to do it myself. I was able to get into boot mode and write a different bin. I over looked and it was for an s4 no immo. I now have the stock tune for the 551al ready.

Now i cant write or read anything as it says the immo is unatherized. Cant get into boot mode. Also jumped the pins and the ecu will go into defualt but cant connect to it.

I also cant connect to vag com. Port is fine but says no interface. Was able to connect before the flash.

To my understanding the tune shouldnt effect the immo as its on the eprom. I should be able to just falsh the stock tune and be done?

Any help would be greatly appreciated.

This leads to another topic dont cross flash unless you know how to recover. Changing software versions risks brick

yah mate this is like the 3rd post like dat in like 2 dayz

Thats what I thought. But before I flashed the s4 tune it was able to connect in boot mode. Then I wrote the bin in. After the flash it now says 0 bytes and can find the ID when trying to connect.

Another problem I found was the drivetrain errors. When trying to write the bin it says Immo unauthorized. It will then disconnect and says waiting for user to connect. After reconnecting it will then try to finish the flash but says "Too many consecutive unsolicited messages from ECU, disconnecting.".

I then hooked a scanner up to it to pull codes and says there is a communication problem with the trans and other components. Makes sense as I have a tip and the tune is not.

I was also wondering if this is ok. When connecting its in kwp2000. It will then switch to KWP1281 session and then switch back to kwp2000 after it has fully connected. It didn't do this before. It was always KWP1281.

Here is the log for trying to flash the stock tune.

Just so you guys know, I'm not a complete noob. I have had my fair share of projects and completely understand the concepts of how and why tune/maps work.

Some get the enjoyment with programing and making their own tunes. I am not one of them. I like to build and get it custom tuned. I'm just in a pickle as it cost hundreds to go get it tuned when at the end of the summer i'm going to be doing a custom build. Get a tune for a couple of months with a poppy stall. Kind of a waste of money.

In this case friend said he could flash a tune. So I let him as I wanted to have some fun as I wont be driving it for a year or more. Plus the only thing I dont want to brake is the heads and block. The stall stucks already so pretty sure my fun will be short.

What's really messed up is I was able to get a different bin in but the wrong one. If I clicked the right one I wouldn't be here lol.

This is what i'm working on. Maxed out the stock fuel map at 17psi.

Hello Nyet.....
I suspected that may catch your attention.
However it wasn't a directed comment and neither was the post in general.More of an observational overview,as I find it.
I am a beneficiary and proponent of your work,and indeed have defended it on this forum and others.

But I stand by my comments in the general sense.
I did start my post with the words "I agree" and I do. I also agree with you, that there is a minority who will always try to avoid any effort in learning.
And yes...I can see that would be frustrating.
However there is also a small minority who, shall we say. "Find it very comfortable being a big fish in a very small pond".

All the very best
O.T.

 
 

Ok. So I have galletto and its in boot mode.

I got the stock file from here.

I get seed key ok
Start writing
Error writing

I tried starting the boot mode process over a few times.

What else should I try?

Make sure its 800bb and not 400bb
