Thanks Peter !! you have been very professional through my enquiry and for that i respect you greatly...... now for the individuals that dont believe ! ! I have spent hours on the phone with Peter discussing and toying with my options but decided not to proceed at this stage and this is why !
1. The cost of shipping if something was to become an issue
2. The intake manifold has to be removed and parts replaced on reinstallation
3. Peter hadn't done a RHD car -But I was reassured this would not be an issue
4. Time and downtime of the Car if the ecu had to be sent back and forth
It has been explained so many times that the ECU once unlocked and reset can be tuned in the first 10 hours in development mode , what more can I say !

ECU out (with the N55 no fun ) sending, sending back, refit the ECU. Also i´m able to describe how it works! The result will be, that BMW will close this back door soon! But i´m not willing to accept such a post without a reply. A 172G is not a big deal. The first way most tuners try is
the direct way via password. This will not work or better it will cause a high computing time. The better way is, remove the ECU, open it, do a reset of the system time (it must be under 10hrs), here you can use available tools, than unlock it and switch it to kind of developer mode. Than change the password retrieval to existing system pswd is not valid, instead the pswd in same bit length is set to valid. Than you are able to read bin file out. Use a tool like Map3d or WinOLS for the remapping after that calculate the checksum. Write it back, switch back to the default mode, re fit the ECU.
Have fun!
