Hey boss- I'm in a 550 tq X5 35d- My trans is shifting jsut as well as 30k miles ago, when I put rod's trans tune on. His tune is FAR superior to XHP stage 3, which I've also had on my car.

Rod doesn't hurt transmissions, he hurts your cheeks from the smiles you'll have plastered on your face. It basically feels like you're no lift shifter a slipper clutch, if that makes sense. It's smooth, and the power doesn't actually stop while shifting.

I was finally able to try out some 1-2 and 2-3 wot shifts with Rod's flash. Somehow there is no noticeable gap in power delivery. I was on stage 3 xhp before. The car will be quicker but will need some drier roads for actual numbers.

I have a 2009 335i that has a Dinan stage 2 tune. What is the cost of the trans tuning?

[Silent9n54]

it sucks that my 03/07 335i has older software which cant be tuned

i was really hoping to test this trans tune out on the track and see the results

It's not older software. It's older hardware. The TCU in a pre-03/07 car is 500gb. The TCU in a post 03/07 car is 1 TB.

Only way to fix this is find a post 03/07 TCU and change it out with yours. It's been done without issues.

hey can you elaborate a bit more about changing the tcu ? who does the coding ?i didnt find any info online about switching it but i heard it can be done. Is it located in the transmission ? i remember some older bmw models had it behind the glove box.

[type-dRew]

if you can do that it would be awesome

best to contact Rod through his website or FB www.sutphintuning.com (Rod Sutphin or Sutphin Tuning) to get a price, I know what he was charging a few months ago but I dont want to misquote. keep in mind this isnt a one tune fits all, he will dial it in to your specific needs. same deal as a custom engine tune

You have to take the transmission filter off & then take the megatronic's (valvebody) unit off where the solenoids are located. It's on the backside of the valve body

I'm confused about the DCT and 6 at zf, the DCT is the manual trans? The e90 335's just came with one auto/ paddle shift trans correct?

6 AT is a six speed automatic.

Manual was an option, which was also a 6 speed.

DCT in non M cars was only offered in the 335is. DCT means dual clutch transmission. It's basically manual that is shifted "automatically", no clutch pedal.

Correction; DCT was offered in normal 335i cars, but only in Europe and Australia I believe.

So it has a regular shifter with no clutch pedal? Never seen that wow.

Or like Steptronic?

[thormessiah]

I've had a Rod's personal trans tune on my car for over 2 months now. Thing is damn flawless. If anything the shifts are so fast that I cant just blast a single gear in one go unless I REALLY FLOOR it. Just the D mode alone is worth it for me.

Can someone share a tutorial on how to create / send the TCU backup file?

Thank you.

Thank you.

under xhp/backups folder in your phone/tablet there is a backup file you can send to the tuner

I see on his website he states using a cable or the thor adapter. Would the orange MDH wifi adapter work as well? Glad I came across this thread. I was planning on going xph stage 3 before summer. This sounds even better.

Me too!!! I was about to buy xHP.

Someone should make this a sticky.....I had ZERO idea this was available until JUST now.

Thanks!

Yes, the orange mhd adapter works. That's what I used.

[iqraceworks]

The last time I flashed my transmission with xHP, I had to use the cable because it would not detect the MHD adapter I have. Did they change something with xHP so that now the orange adapters will work??

[zomski101]

It worked for me since the initial release date of the mhd adapter. Maybe try connecting to mhd, like read error codes, then connect to xhp.
