On the release date, I installed the xHP program, and did not follow the steps.
My car is a 02/07 model. So i doubted I had it, but since the App was free I decided to check my firmware however seems I got lucky and had the new TCU 7591971.
The App sets out steps one by one.
Agree it took awhile as the TCU was to be backed up (had JFA TCU Flash prior)
Afterwards you would purchase a $100 license, and the OTS map.
I went with the Stage 3 (how could you not?!)
Since my battery wanted to die as the App told me I was on 11.5v or so, I had to hook it up to my Mum's car 
It is beautiful this flash, best thing I ever did, shifts so fast and is a large improvement over the Alpinas and the JFA, dont even care I didnt get DCT anymore, but still sad not having the 'fart' i guess.
Anywho ECU Holds torque well and shifts at perfect rpm bands.
There is currently work from users to edit the custom maps and make it a bit better on the BMW 135i 335i page on Facebook if anyone wanted to contribute.
With the INPA Cable and USB cables I bought from ebay they worked splendidly.

Must do. Good luck all |
Good to hear positive reviews on xHP!
So $100 for the licence to flash and another $150 for the stage 3 flash?
All up $250 aussie dollars?
Be interested to see if there are fuel economy benefits with the faster dct-like shifts.
