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!

I would want to know the file source is not corrupt. To down load a virus would be painfull!
Any idea id the blueTooth OBDII connectors are any good?

Like this one: ELM/327 OBD2 OBDII Bluetooth Diagnostic Interface 1.4 | eBay


Anyone up to do a walk through, step by step guide? screen shots and photos etc would be a great help for those that have never ventured down this route!


What a panic! All can be easily fixed with normal D-CAN interface!
Is the interface lead different from the Inpa K+Can lead?

Can you respond with more detail on how to go about fixing the software issue 335xi has please ASAP as he will be incurr cost.


I'd be interested as well, the clones are close to $800ish with the real deal coming in at $4000+

i have another question now, is there a good guide for how to operate the euro launch control?



Have a look at the attached.





Will this work with Windows 7 or is it XP only?

Is that an ICOM from china? I think I posted a link to these...
