My DCT conversion to M3 GWS/FLASH

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.
buddy how can i contact you i really need your help...

I've just got my 135i swapped to the M3 GWS DCT setup. I also put in the M3 kombi. Has anyone gotten the shift lights working?

I think @superwofy built a canbus device that translates data and makes it all happen.
There’s a thread on here. The device does a heap of other cool stuff as well

Yeah I found a post where LMB335is mentions its an M3 DME signal. Found another on e90 post where someone used an arduino... not sure I want to add the complexity. LMB335is has a youtube video showing them working that he posted recently but I guess he used a can module...

It's a add on kit soldered directly onto the led circuit and then taps for +,-, and tach signal. Certainly not the preferred way I'd want to do this but the unit has 16 different rpm maps to choose from so it can be used in any E9x application regardless of engine/trans.

BMW 335 N54 E93 with M3 GWS and GTS Software. Tks to Alec!!!

All working fine escept one litle issue, some times when i left the gas pedal in 3.000 or 4.000 rpm, i got some delay and rpm oscilation, looks like the clutch desengage to change the next gear but have some 400-500 rpm oscilation. Just happen when i left the gas pedal. With pedal pressed, the gearbox change the gears fine.

This not occurs every time or with WOT.

In D mode and 20-30% pedal, all working fine.
M mode no problens, like the tork puntch, the tires doesnt like

How did you do the trim to hold the Drive logic switch?
