I attempted this on my 2008 E90 M3 6mt, that came with Active Autowerke tune from previous owner, and ran into a few oddities/issues:
- After the Read Full Flash completed, I went to 'Read ISN / Secret Key’ as recommended and I got the message: "Could not find secret key".
- I then attempted the RSA Bypass; clicked Load File using my same full file dump, chose Slow option and got message: "The file you loaded is not a stock binary. The RSA bypass requires a stock binary be used."
I'm guessing both of the above could be cause of the AA tune? I don't have the stock tune file for my car since it came with the AA tune from the previous owner, who had it installed with full AA exhaust with HFC.
​
- Lastly, I booted up the MSS60_Binary_Modification_Tool_V1.9.5 to see my full dump file settings, and got message: "Out of date / unsupported software version detected! Please upgrade your DME to 240/241E."
Thanks in advance!
