MSS6x Flasher - Now released!

[SYT_Shadow]

I don’t think so. The used dme I bought had a build date near there and was locked until I unlocked it.

If you’d be able to reflash your tune afterwards, I suppose you can restore to stock, do a full backup, unlock the dme, restore the backup, flash the tune, and then read the full contents over bdm.

In theory we would indeed be able to reflash our tune afterwards, as we already had it to begin with.

I'm just not sure how to read it when the program says it cannot read

terra hi

i send You a private message
can You look please my message
thank you

This is a bit confusing.

If one of my cars was not tuned, what are the steps?
-flash the car with 240E software to coincide with the tuned car version
-execute a 'rsa bypass' with the tool?
-load tune
?


I'm pretty happy I can enable cold start on the stroker engine now!

That would basically be the process, yes. If it’s on 241E, you could just use the 240E tune (they’re interchangeable)

If both ECU have a custom tune the RSA bypass is already installed and so you just have to load the correct tune and push "flash tune".

Assuming both ECUs are on the same program version

It's odd. It worked fine.

I went to the E92, identify DME, then 'read tune'. It reads it and saves it on the drive.
Then I went to the E90, identify DME, then 'read tune'. It reads it as well.

So now all I have to do is go to the E90, take file from the E92 and 'load tune'?

My build date is 2008-04-10 is that early enough?

If you can do a BDM backup then it'd be possible to defeat the bypass in there and reflash, but unless you own a very early M3, your DME will be BDM locked.

Shouldn't we be able to bypass tune read protections on the ECUs?

What if I have a tune with read protection but want to remove or add cold start for example? There should be a way to do that

Unfortunately with the way the flash routines are setup on the MSS6x, it's not really doable without wiping out the tune altogether. If you can do a BDM backup then it'd be possible to defeat the bypass in there and reflash, but unless you own a very early M3, your DME will be BDM locked.

I think it's done for tuners IP protection and to force you to go back to the tuner to make any changes.

In order to find out all I have to do is try to read the tune? 'Read tune'?

Yes, try it and let us know how it goes. I was planning to order a new cable and try it out, but haven't yet.

[SYT_Shadow]

My tunes were encrypted and it was unable to read them. I would imagine you would have the same issue?

I have so many questions...

I bought the special bimmergeeks cable following the instructions in the OP. I probably already have 6 cables that would work but it's best not to brick the ECUs.

I have two E9X M3s, a 2013 6MT E92 and a 2011 DCT E90. Both have different aftermarket tunes on them. Originally the 2013 was the track car and has a catless tune, but now the situation is reversed. I would like to basically swap tunes.
To do this, I 'read tune' from car 1, save the file, then go to car 2 and 'flash tune'?
