My DCT conversion to M3 GWS/FLASH
- Thread starter dyezak
- Start date
Does not work for me
Ideas on troubleshoot?
Also i can t stay in N after i shutdown. Any ideas?
That sounds like the parking 'detect' wire isn't hooked up? Are you getting the warning relating to 'car will move'? There is a tiny plug on side of GWS that must be connected...
There is some reverse engineering/CAN shield work in progress but nothing as of yet. There have been efforts to crack the bytes/nibbles needed to illuminate the shift lights but is a bit elusive.
I have lost track ... do you have comfort access? You will need to have the key in the slot.
Yes. I have comfort access. And yes. I read i needed to have the key in the slot in order to have the car stay in N when shutting off. When i found that out, i was able to successfully complete the full relearning of the dct.
if one wants to do this conversion ..I am selling my M3 parts because of vehicle sales

I know it's been a long time since someone wrote on this topic but i want to make this retrofit on my 335i N54 DCT. The problem is that i just only want to change the Shift Knob and the GWS. So i have some questions.
1. After installing the GWS and the Shift Knob (and making the repin), the gearshift will automatically start in N?
2. Is there any possible way to code the gear to start in N ?
3. Will there appear any unlock selecting gear error since there's no unlock button on the shift knob?
I have XHP FlashTool, in my mind i wanted to install only the shift knob, but the main center console to remain the original one, not the M3's. That's why i don't want to install the M3 Software on it.

you need the m3 tcu software since the shifter is totally different how it works, the 335is flash just won’t know how to deal with the m3 shifter. Now when most of these swaps were done and written it was pre XHP.
I’m pretty sure when you flash XHP it’s a modified version of the m3 Gts bin. So it might actually work just to swap the GWS , imo you are just going to have to try it and enable , with coding , the m sport on kombi (cluster). Car always starts in N with the m3 flash, there is no park button on m3 gws. You need to use ebrake when running in N or when car is turned off the parking lock engages.
335is bezel around the m3 shifter won’t work without modifying. Bill gee might jump in on convo he’s done a lot more swaps than anyone probably and will know a lot more definitive answers on what could work now.
As I explained on E90 post,
1. Installing a M3 GWS on a DCT with non M software will have a software mismatch between the GWS and DCT and resulting errors. It's not something you can just code out. A properly done conversion starts in P.
2. No
3. Yes there will be errors, lots of them.
The xHP software is designed for the non M GWS. They don't support M3 DCT software or the GWS. A look at the supported vehicles on their website will comfirm this.

@Olza can probably help you with 335i software converted to work with M3 GWS.
When xHP came out, they said no to allowing the M3 GWS, so I went to Ozla to help me with a custom TCU tune so I could have different Axel ratio and use the M3 GWS. We made shift mode 6 very usable in drive mode for track use. Lol

Do you know if Olza’s custom tune increases the line pressures? Or only axle ratio adjustments?
