If I were to myself tackle this swap, who would I need to talk to for the tune aspect of the job? The swap itself seems straight forward but it's everything else I'm not sure about

DCT paddle shifters when though?

Hi there please do you have the wiring diagram for the swap I’m doing for e90 335i

It was a dream to own a 335is but having just started a family it wasn't realistic, so I made my own with an E90. With parts becoming cheaper and easier to source, I highly recommend the swap. To me it was worth it, just as much as upgrading turbos. I'll try to post some videos in the near future...

With all that said, I want to say thanks to some people. Without there opinions, feedback, support, and help, this would of never happened.

First my wife, putting up with so much bullsh1t and allowing me doing this. You're amazing!
To one of my oldest and best friends BoostNinja. You have supported me from our DSM days to now. I can't thank you enough for all the work you have done for me. This car is f@cking amazing.
My good friend Turbocripple, thank you for being Terry's guinea pig on the first swap and for keeping me focused on my build. All your enthusiasm and positivity kept me going.
BaruQ, thank you for dealing with Terry and I. You did a fantastic job on the tune and squashed any doubts I had about how my car would perform. IMO you're the best of the best, and would recommend you to anyone.
Sirdaft, us talking a few years back about programming the auto transmissions (before it happend) for better shifts or a DCT swap when I came to buy your CSL trunk (which i've still have not installed). You gave me the nudge to want to do this. Good luck with your build.
Last but not least, thank you to the whole N54 community and the people who took the risk to have more. Sharing your information has helped everyone.

I do know of a couple E91 w/ N54 and DCT swap.

Can you please inform me of who to contact, and from what stage they came from (either manual or automatic) and 8 bolt versus 6 bolt pattern.

Thanks

Did you have to do any coding? Who did that for you? Do you mind showing what you did to get it to work? Any toggles or apps we had to use? (If you did have to code)
Thanks for all the info by the way! This definitely gets my hopes up on my future project!
