E60 M5 DCT Transmission Swap

Guys the time has officially to come to take my beast to another level. I was experiencing numerous problems with my SMG transmission and I didn't like the jerkiness. I am a huge fan of the E92 M3 DCT transmission because of how instant and quick the shifts are. Not to mention the less problem it causes; the DCT on those are solid reliable transmissions. BMW did a great job with the glorious NA V10 engine but did not perfect the automated transmission. I ordered the E92 M3 DCT transmission and flywheel yesterday and will start shipment next week. The shop who is going to make this amazing build is going to be Gintani. Gintani is well-known for their supercharger and twin-turbo kits they offer for M cars. At there facility, I saw an amazing build project which was a 2010 M6 with a twin-turbo kit pushing easily over 1000+ horsepower also equipped with their DCT transmission to handle perfect with the beast. My whole build is going to take roughly a month to complete and I can't wait till the parts come in! I will update you guys every time I have new updates on this build.
Have you seen that car run? That's an incredible achievement, it's hard to believe there are no videos of it anywhere.

Maybe the programming will fix this, would love to know.
Not unless they've figured out way to reprogram the DSC as well. One set of wheel speeds directly feed the DME, another set is transmitted over PT-CAN from DSC to DME. Not likely anyones altering DSC module code, it doesn't have separate calibration area like the DME and no A2L (map file) is available; all changes would be made in program code via reverse engineering the disassembled code.

Way easier to swap the rear ratio and keep everyone happy.
 
I've followed along and kept my thoughts much to myself as I feel it would be inappropriate to voice anything other than a technical opinion.

CIC would only interface with the DME on one bus, the K-CAN bus as transported over the gateway to PT-CAN via the KGM module. You can remove the CIC or CCC entirely from an E6x SMG or E9x DCT vehicle and the car will still drive and shift via GWS (gear lever for DCT) or paddles and lever and paddles for SMG. There are hundreds of cars out there that have had CCCs replaced without VIN programming (dealerships are not capable/will not do it) as well as many CIC retrofits done without writing the UIF when programming.

I certainly think this is possible and in what little time I've had to investigate binaries, I'm starting to think this is not as difficult as it's been made out to be and certainly not reliant on a single very clever individual with OEM level developmental software access to see it through.

From the CIC/CCC/iDrive perspective, the only powertrain related functionality that is of concern is the passing of the appropriate commands to the DME to set the default shift mode, DSC setting, EDC setting, Power setting, etc to the M drive configuration. These functions are all signaled in reality by the DME, not the CIC. All the iDrive does is give a nice menu to select the appropriate settings which are then transmitted via K-CAN through the KGM (for conversion to PT-CAN) to be received by the DME and saved. These settings are then acted upon when a press of the M button is detected and the DME transmits the M Drive configuration signals back out over PT-CAN to the DSC and EDC for the appropriate settings.

I'm hopeful that Gintani will complete this soon. I think it's a viable option for the future of this platform, but certainly not for everyone as the diagnostics/calibration(adaptation)/maintenance of the car will be impossible for anyone other than the shop that installed it. ISTA would never even probe the DCT for errors or be able to perform an adaptation. Maintenance would forever more require a custom written set of .IPS scripts for INPA and there are few shops anywhere that go into that level of INPA. Hopefully that's something that was considered up front in this case as well.
 
He contacted me via FB, once he starts talking he never stops lol!!


Hopefully we can get this project completed sooner rather than later.

This is why I prefer email of phone calls. If you think I get excited in written communication...

A simple phone call kills an hour of my productivity. I like trying to figure things out and help people, but I destroy my throughput in the process. I tend to write more succinctly.

Agreed though, let's leave this for OP and hope he has something working soon.
