Yes it would be wiser to wait until your 1200 mile service. Dealer will probably flash your car with newest software which eliminates ability to code.

Worse that could happen is that the dealer re-falshes your car during service and you have to recode Euro-MDM afterwards. No harm in coding it right away.

There is a local guy around here coding on the new version. Wonder how he's doing it?

Just thought I'd add my 2¢ on this. I coded Euro MDM recently and LOVE IT! So much more fun.

I did not code the last two lines. Doesn't appear they are needed, and I think that, as speculated elsewhere in this thread, they are just date values.

This change absolutely can get you in to trouble...if you're aggressively maneuvering the fail-safes will kick in too late to save you, so make sure you're comfortable handling & correcting out of oversteer situations. If you're not overly aggressive they will help reign you in, but the car is much more lenient & you will get bitten if you're not careful. You can really get the tail to swing in Euro MDM.

Aside from kicking the back end out, I find that it makes a big improvement in accelerating out of a corner. Standard MDM would limit the throttle too much for my liking. Euro MDM lets it rip.

If you find that standard MDM is still too restrictive & full off is unnerving, Euro MDM is a great option. Truthfully, I wish I could have all four options.

However, in my opinion Euro MDM is closer to full off than it is to standard MDM. When I was testing it out I found that, if I was really getting after it, I could spin the car 3/4 of a full rotation. That's a lot of looseness & not much actual "traction control."

So, proceed with caution, but do proceed. If you can handle the car it is so worth it. Gives you most of the fun of DSC Off with a little bit of computer help.

However, as others have stated, if you *really can* handle the car just go DSC OFF & hang on

Most of the time, I like a little safety net, and I feel like Euro MDM is perfect.

MANY THANKS to shawnsheridan & others who have contributed to these coding threads. I loved my car before, and I love it even more now

I have to dissagree with the above statement. Euro-MDM remains a full fledged stability system even if it allows higher slip angles. I agree that it much improves the enjoyment of the F8X, but it remains quite intrusive when pushed at higher speeds. Even at lower speeds, it will allow you to "kick the tail out" but will not allow you to sustain slides.

Going DSC off is still a big step up in driving experience (and risk) even from Euro MDM.

Can someone code us a Bimmerpost MDM?

Just for clarification, when coding EU MDM, why are people changing the TPMS region from US to EU? Isn't this telling the car what kind of TPMS hardware is installed?

I have been wondering about this too, as it is unclear to me whether the parameter in question (CTpmsMarket) identifies the hardware variant of the car or sets the mode of operation of the software. The same applies to C_Laenderkennung, which is described in the acompanying comment as a parameter used to "control country-specific characteristics, for example MDM" (Google translation).

My hunch is that the first parameter is more likely to refer to the hardware variant and the second to the software mode, but on the other hand the TPMS readings in the Vehicle Status display appear to work fine no matter how CTpmsMarket is set and the OEM tires are the same, so perhaps it makes no difference either way.

With a different " digital screwdriver ".

It's code ... All it takes it someone who knows what they are doing to start trying to break it. See: hacking 101

I agree.. I actually wish I I could have all 4 levels. but if I have to standard or euro then give me euro.

Very good point about literally getting being able to go nearly 270 before the nannies kick in.

What do you guys mean by "nearly 270" ?

¾ of a full 360 spin?

I seriously doubt Euro-MDM lets you do a 270 rotation before kicking-in, it would toally defeat the purpose. Either you are bullshitting nonsense, or you did something totally stupid and Euro-MDM could not bring you back in line.

Doing some instructor training, I was purposfully adding throttle while pinching the steering wheel in the wet to see if the instructor candidate would pick up my mistake. I could get the rear to step out quite a bit, but even Euro MDM would kick in quite abruptly to reel me back...

yes.. this.. Guilty as charged... is it okay if it was for " science" ?

I don't hoon around on the street really at all.. I autocross and track my car responsibly.

However.. when I first decided to really test my euro MDM... I decided to do a 90 degree power turn... starting from a standstill at a traffic light. Light changes to green..... ROMP the accelerator firmly.... begin turning.. basically it was the beginning of a large donut... and it surprised me.. it probably didn't get to 270 so perhaps a slight exaggeration... but essentially.. the point is... one can really build up so much potential energy in the chassis... that there's no way the nannies can react quickly enough to stop all the kinetic energy ... Ala the Sakhir Orange M4 ollieing a curb ....


Exactly as you indicated... one CAN get over one's head with Euro MDM... especially on the street.
Regular MDM is much more suited to normal street driving.. and will save the even the most reckless driver.
Do something *really* stupid with Euro MDM and you will flat out find yourself in a ditch. A driver simply can be too stupid.

[ASAP]

I am still trying to figure out how this euro mdm is so reckless... is the assumption that European drivers are tha much better? C'mon now... common sense

[heckyeahbro69]

so if euro mdm allows me to do 270s what does us mdm allow?

but seriously, a 270? your car spun around, faced backwards then kept on spinning? then mdm was able to bring it back around a full 270 the other direction? those engineers in munich really know what's up. I need to try this. brb

my car is June build 2015, and C_Codierdatum is 15,06,09, so it seems to be the date of coding (factory).

Are there any difference in the parameters needing changing on a F10 M5?

When I tried the M5 at the M Driving School, the US MDM on the M5 did not seem as intrusive as that on the M3/M4 (they asked us to keep MDM on all the time), so I am actually curious about this.

Have you checked if your current settings match the US F8x settings Shawn mentioned in post #4?

I will be checking tonight and I'll report back!

[dbworld4k]

Update: on the F10 the only parameter listed on page 1 that exists is the C_Laenwhatchamacallit and the options are only US and something else. No EU or ECE.

Thoughts?

So now you know that the settings are indeed different between the M5 and M3/M4.

Can you PM me (or post) the CAFD for your DSC module? I might be able to check this for you.

Edit: Got the CAFD. The only difference in your F10 ZCP should be in C_Laenderkennung (ECE is initwert=00, US is US=01).
