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
Process would generally be:
1) Restore DME to stock and read that backup
2) Unlock the left CPU (this will delete the contents of that CPU in its entirety).
3) Restore your backup to that left CPU via BDM
4) Flash your tune back using your tuner's cable or whatever
5) Read the tune via BDM
From there, one could probably figure out what needs to be changed to allow OBD reads with the tuned program.

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.

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!

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".

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'?

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
