Edited by mod: DO NOT attempt to flash an LCI (08+) car unless you have a firmware-correct k/dcan cable. Only cable known to work is Bimmergeeks. If you brick your TCM you were warned!. See DIY sticky for link to exact post with updated instructions.

As we have seen the last few months coding has taken off! More and more people are offering windows up with remote, full bright angel eyes with headlights on, and more. Well here is the next step. Reflashing modules!

Euro smg software features:
-4k rpm launch control with auto shift at red line in S6
-Default S5 / D1 settings from cold start (US default S3/D3)
-Smoother / quicker shifts between gears

I didn't make a video however you can find several examples of it on youtube, here is one:

Attached is a guide made by terraphantm on m3forum. You can use the exact same process however instead of using E46 files you need E60 files and instead of using the #ZB number for SMGII CSL use one of the above.

Besides already flashing many E46 M3's with different tunes I have also done Rnydyman M5 with the euro smg software who i'm sure will give you his thoughts!

Hope everyone finds this information useful!

Awesome, I already have cable + NCSExpert - Doing it this weekend!!!!

What do you guys think about the warranty? Will this void it? I mean, we're putting authentic M5 software in the car.....
I see a couple of vague instructions in the pdf:

Using DIS or INPA clear any codes that may be stored in any modules.
10. Start the car and enjoy your improved shifts! You may need to run the SMG adaption procedures

As far as needing a power supply

Here is a link to a torrent with everything you need for this.
Would a fully charged battery and this: CTEK Multi US 7002 12V Battery Charger: Automotive

be sufficient?
Besides the launch control, how much improvement did you see in everyday shifts?
When I was done setting up WinKFP before I even try to do the flash this is what is in the window.
ECU Address etc... 18 Unverbaut
Assembly Identification Number: 7842206
Hardware Number: 7842205
HW interface: STD:OBD_ Diagnosis protocol: BMW-FAST

PABD: 07gdsmg3.IPO

Does that look accurate?

OMG, It did not work, it stopped at 40% I think it broke my car!!!

Doesn't look any different than mine..... Those 'Access Denied' errors are making me worry. How many times did you push the 'start' button?
I put my key in the slot and pushed the button 2 times I think until all the interior stuff came on.
OK, while my slow xp laptop is loading, i tried disconnecting the battery

You should have the check engine light on. Carefull when you close the door it can go back to stereo only.
That did not accomplish anything. Car won't start, SMG stick does not move and when I turn off the ignition, the SMG pump just goes 'psst' really quick. It doesnt prime when I unlock the car.
I am starting to suspect my cable may be faulty after it worked fine for over a year. Is anyone here with a cable near by Stamford, CT ?
I would discourage anyone from doing this. There can be unforeseen consequences.
The problem is there's not enough know-how to correct possible issues

What unforeseen consequences are you referring to? Why post such a statement like that without giving any details at all?

Many people have successfully modded their software on E60, E63, E90's with no issues. Take a look at for complete information on how to do this.

True, there are risks associated with performing any mod, including strictly hardware mods, but why make a blanket statement without pointing out any SPECIFIC issues that you personally have encountered.

If an issue does arise, even people well-versed in the software and the cars can be at a loss. For all the techie peoples, flashing an M5 is not the same as updating the firmware on your cell phone. There are millions of people flashing phones thus there is plenty of knowledge base to go around to figure out almost anything that can go wrong.
I am hoping that a complete reflash of the car by the dealer will correct everything

OK, sorry to the poster for my ignorance of not reading the last few posts.

Sorry to hear about the troubles encountered. As with any mod, there is always that risk which we all assume. Things can and WILL go wrong for a some.

I can understand the warning. I hope you get it sorted out without too serious a hit to the wallet.

Hopefully they will be able to get around the 'SECURITY ACCESS DENIED' issue I saw.
Yes, I had a CTek 7002 (7 Amps) plugged in

335xi - did you have your car hooked up to a trickle charger when flashing the software? If there is any voltage fluctuation during the flash, the computer will 'brick' itself (if it's anything like the majority of other ECUs out there). I'm sorry for the problems your having :(
Now, the real question. Vodyk was trying to help and he was able to flash up to 100% and then we'd get the 'Access Denied' message again. Do you think the dealer will have better luck?
Yeah, please enlighten us

What a panic! All can be easily fixed with normal D-CAN interface!
Seriously, how?
If that's all it is, hopefully the dealer should be able to go around it and perform the flash

That's the concern - Vodyk thinks it could be the version of SMG software that the cars are running. It looks (from what Vodyk tells me, and what he posted) that there are three versions. I'm reasonably sure that I had the second version on my car when we updated the software, but we didn't make a note of it, so there's no way to know for sure. I had the SMG control unit replaced when the clutch was done - this was probably in 2008, but I have no record of which software version they installed on my car. So... that's where we're at so far. Vodyk's theory on this is that there is a security measure installed in the later SMG versions of the software. If your car was updated AT THE DEALER in 2008 (just to be on the safe side...) DO NOT TRY TO UPLOAD....

I really don't want to pay for new ECU....
Yes, I am waiting for the call

Have you taken your car to the dealer yet? We are still waiting to hear from a contact there.
To tell me whether they can flash or If I need to be taken to the cleaners.
I just got a call from dealer as well

Talked to the IT guy at the local BMW. He said that they cannot flash EURO software. BMW doesn't allow it. He also said most likely some part of the MOST system rejected it for some reason. Like maybe the gear selector and that for about 1.5 or two hours they would charge to reprogram.
They are saying they are having communication issues with the car still. They will continue trying tomorrow.

Thanks. I was just curious what you guys said when you got there. 335xi, since you're trying for the warranty fix: May I recommend the method I used to use when I had a warranty?

S.A. "What seems to be the problem?"

Me "Yo man, mah **** is BROKE!"

S.A. ".... Ok.... Well, we can fit you in tomorrow... Do you need a loaner?"

True story.
I think I will offer to pay for the flash since I feel it's the ethical thing to do but the reason I did this was because of the crappy US SMG implementation. If they gave us the proper software we wouldn't be in this situation.
I take it you're not married ?

This Is all in the nature of modding cars. Especially now. With computers to work around. Etc.

There were about 5 people there when I was doing mine. Once it bricked they thought id be pissed. I was giggling. **** happens. I have another car. And I tried.
My wife thought I was a [email protected] for messing with my M5 :)
What's up with all the Black M5's looking to Mod? I just noticed that.
