Can be done remotely. Doesn't need to be in person and you don't have to send your computer out.

DME is a seperate control unit and controls the Engine - (Digital Motor Electronics).

Euro MDM is activated in the DSC (Dynamic Stability Control) module. The M3 has a particular DSC module different from non-M variants.

You can send your DSC module here for programming or the remote coding for MDM will work as well. See the coding PDF in my signature on how remote coding works.

I need to do more research on this. If there is no physical hardware changes between the two (meaning different struts, etc..), then I am 100% confident that I can retrofit the ZCP EDC to non ZCP cars.

These are things that I am planning on taking a look into in depth as time permits.

Thanks for the info, PM sent! Interested to hear other's views on Euro MDM that have used it as well. Any idea how great the increase in slip angle is? US MDM is not bad for high speed stuff but definitely intrusive in tight corners.

And what's the difference between Euro MDM and the competition package MDM which is supposed to be different from the regular one?

ZCP struts are different than the non-ZCP struts, but the EDC module can't detect the difference between the two or anything.

Correct on this - the question is on the electronics that control the dampening. The EDC module is certainly the same and I can code that with ZCP settings without issue. However, if there is something else changed between the EDC module and the struts, then it may not be possible without changing parts.

I am not sure as I have not done any research here, need to check into it.
If there are changed parts, putting them in would allow a non ZCP car to have the flexibility of ZCP cars with EDC. If the hardware is all the same, then I'll add another possible retrofit to my list possible with coding alone

I will probably have some time on Friday to code the settings to ZCP and see what happens.

To my understanding the non ZCP cars have adaptable dampening in Normal Mode, where as with the ZCP cars the dampening occurs in more than just normal mode. Would you say this is accurate, or is there another change on top of this?

My understanding is that on non-ZCP cars, the Comfort and Normal modes are dynamic while the Sport mode is fixed. On ZCP cars all 3 modes are dynamic, with the Comfort and Normal modes being the same as on non-ZCP cars. So the only difference is the dynamic Sport mode.

The Normal and Comfort EDC settings are the same across ZCP and non-ZCP cars. The dampening for Sport EDC setting in ZCP cars is dynamic, whereas it's static in non-ZCP cars.

By the way, I've done the hardware ZCP retrofit on my car, but not the software to get the dynamic Sport EDC setting.

Interesting. The sport doesnt feel dynamic to me. Not saying it isn't but I don't notice the difference like I do with mag ride where it firms up but still feels like compliance is adjusting. Sometimes I think Chevy engineers don't get the credit they deserve.

Maybe my expectations were too high but I definitely coded it correctly. Somebody from the other forum was saying that you can drift with Euro MDM but that is simply not true (because I tried). However, from reviewing the video from the past weekend it does seem that the traction control light flashes a little less than the prior track day back in February. But as far as letting you go into higher slip angles, I can't be 100% but it does seem the car will let you slip more but I was still unable to use it to rotate the car as much as I would like. I got much better results after I turned DSC off. This car is so balanced, traction control really isn't necessary once you learn the car's characteristics.

Here's the quote that caused me to have such high expectations:

with "nicht_aktiv" and US-VEHICLE "nicht aktiv" you are able to drift in MDM mode.
all settings for US market are extremly carefully.

DSC OFF - This is what I expected from Euro MDM. To rotate the car with the throttle.


Euro MDM - Going into turn 1 at VIR, the car was put into a higher slip angle and it started reducing power and kept reducing power until the car is straight. Very disappointing, but not unexpected.

I guess it depends on what one defines as 'drifting.' In many videos where backend of a car comes out just a tad (which even US MDM will do), you often see people going "woo, nice drifting."

No way you will be able to 'drift' even with Euro MDM. You can smash through corners pretty briskly, but nothing like a full drift.

It's not intended for this, you will need DSC off for that - and be careful!

If you want to get around the track FAST without killing yourself, Euro MDM is perfect.

PS - I enjoyed the vid, thanks for posting. Looks like a badass track!

Hi, this is my first post on this forum.

I own a 2008 Euro M3 sedan without Competition pack. I have to say, the MDM does not allow anything which might be called drifting. It even cuts the power when quickly shifting from 2nd to 3rd.

I will change to the Competition pack MDM as this allows more drift angle and tyre slip. According to the guy who did the calibration it is no problem to flash this on my vehicle and he will be the one doing the modification. Will be interesting...

MDM is great to drive safely but fast on a wet track (I tried it on the Nürburgring GP circuit). But even there it limited the vehicle dynamics too much in for my taste. So I had to drive with DSC off which is very easy with the M3 as it is very predictable to drive.

Welcome to the forum and thanks for your review.

Just performed the change to a couple of E60 M5s yesterday - they are simply loving it.

So to Activate Euro MDM, all you have to do is change this?

Seems to me that "drifting" is, after you get the car sideways ("initiate" a drift), you're able to keep it sideways with throttle & steering.
