MDM euro Coding

Ok maybe I can try

[terahertz]

Maybe I spoke too soon. 20 mph right turn 2nd gear flooring it the dsc light was flashing and i was getting power cut without wheel spin. I'll wait for your review aboulfad . There's too many variables for me to make a definite conclusion.

Hi terahertz , on Monday I'll head to a track for the first time and hope I can drive with EuroMDM. This is no review or a detailed analytical observations but sketches of different experiences....

I have rolled back the parameters (amr) as you did and driven a bit. There's a place where I am free to accelerate in straight line that I used since I got the car and I recall that when I rolled on the accelerator (not stomp), the car in the past would go sideways a bit, adjust (diff action) and continue straight.

Now will all the permutations and all different values and settings that I have tried based on this thread, the car just kills/cuts/limits the power, you hear it and see the light flash... Yesterday it surprised me as the tires were warm, it was warm outside (25C) and expected good grip and that it wouldn't cut/limit power but it did under the same speed and accelerator application method and I believe I felt it applying the outer rear left brake where in the past I believe it didn't.

Also I have another place with a turn, that I usually induce oversteer for fun, and also it is less tail happy. The only observation I can make, wether true or false, is that I don't know what MDM is supposed to do under different conditions/variables and that something changed between old and newer software.

I just spent 2 days in the mountains on some of the twistiest roads east of the Mississippi (the Smokey Mountains in Tennessee featuring the Tail of the Dragon).

And I have the newly-coded Euro MDM....which I had to fully code since I have PSxD 57.1.

For me, the new Euro MDM is just about perfect.

First, let me say, I have the stock Contis, which have little grip, which for now I like. ...because it enables me to do burnouts in 2nd and 3rd all day. LOL I spent most of the my hard driving in 2nd and 3rd gears, rarely did I need to go to 4th. In Euro MDM, when hammering it in second or third with the DCT, the car would go a little sideways and then give me a catch-able slide, that I could steer with the throttle. Rarely did MDM ever intervene. In the US mode, it still intervened too early, cutting off the power, and the fun.

But in the new Euro MDM, I could get sideways, and luckily I could control it. I turned off the DSC completely one time, and the car didn't feel secure enough for me to floor the pedal on a twisty country road. But with Euro, I could, and would feel confident that it would give me just enough rope.

Where Euro did consistenly intervene, it was when I slammed on it in first gear. It wouldn't let me do a full burnout, of course like you can with DSC off. And it shouldn't. But in 2nd and 3rd gear, it let me get sideways (and I liked that).

Having said that, with Euro, you better know how to catch a slide...because it will give you enough to hang your Self if you're not careful.

But I LOVED it.

I really liked my M before, but now, after 2 days in the mountains, my love affair has officially started. The full AA exhaust (which drones a tad on the highway, and can be a little loud around town inside the cabin at lower speeds), the squeaky CCBs, the harsh-ride of the KW V3s (almost unbearable in a poorly-paved city), and the beautiful AWE intake....they all came together magnificently in the mountains.

I just rolled down the windows all day, and listened to the pops and backfires, the intake swooshing in air, and the car breaking loose at a moment's notice, and it was HEAVEN.

Now, when I drive it around town, and I feel every bump, and it's a little loud so we have to talk a little louder in the cabin at times, and the brakes start to squeak a little....it will all be forgiven.

Because when you're in love, all blemishes are masked by pure adulation. LOL

Exactly what I said, I was hoping it would've been as easy as that but unfortunately not.

No flashing indicator, just a delay just after you shift to 4th gear before you get the full power but after that slight delay it goes like crazy.

dmnc, many thanks to you again (and Shawn as well who pushed me to just code the car myself). I wouldn't truly love my M4 without all of you and Shawn's support and patience.

I can only applaud and offer my utmost respect for what you two bring to this community.



This pic's for you.

Sorry to disappoint, but my nerves were shot that I didn't try anything on fhe track yesterday, maybe next few visits after I get comfortable

After reading the cryptic/warning posts from miamiten, I decided to reset those params to 0 until someone can share or PM some specific details. For now, I have just set the only parameter as described in post 341.

[terahertz]

Anybody else feel like trying? The car drives perfectly fine with the older AMR values, but I just can't remember what 57.2 felt like!

Worse case I'll just have to extract the 57.3 and flash it back.

The link is still there I will ask next Monday and bring my laptop if I or the instructor can drive the car and try to gather some opinions based on changing the amr params. Given the most recent discussions in general, it seems there are some members that reverted back to 57 and thus implying some change in firmware that potentially impacted something related to the car's handling.

I've figured out the references for werte values AMR_2 & 3. They go back to ICM and pre-set "degraded" settings. It's all rather complicated as DME, DSC, ABS, ICM, BDC, GHKS, VDM (if equipped), and CAS all have to work together and for the appropriate delegated functions.

In English please, So we just leave them alone and call it a day? Btw is it BDC or VDC, GHKS or GHAS ?

Hey folks,

I've read all 18 pages here and did my best to follow the contents of each post. I have an 04/16 build ZCP and coded my car to Euro 2 for PSdZData 59.x. If I understand correctly, Euro 2 is just like Euro 1 in the table below, but with the CTpmsMarket value of 01 (US).

I went from US to Euro and back to US again and IMHO, so far they feel about the same to me. Both cut in earlier than expected but do so very smoothly.

I wonder if the guys with PSdZData 57.x. got the good stuff or if ZCP for 59.x is just more similar to the Euro version?

[dmk08]

I am too wondering what to do about Euro MDM coding for my new ZCP. I was going to code the car today with 59.x but I'm wondering as you said what differences were already made to the zcp.

I have 59.2 and coded for Euro MDM by changing to ECE only as done by "cheat codes" in E-Sys. Euro MDM let me get rear sideways coming out of parking lot and allowed me time to make driver inputs to bring car back in line. I also stomped on gas in second gear (6MT) and tires spun for about 2 seconds and then the car hooked. No flashing on the instrument cluster and no engagement of MDM nannies. Car felt really good.......really good!!!

So, having read the last few pages, I'm hoping someone can point me in the right direction.

I have a '16 F82 non-ZCP, which I had previously coded to Euro MDM.

I just had the software updated (need to confirm version, but I believe the latest 59.x) so need to re-code everything.

What is the best setting so far for a non-zcp with latest software updates?

This seems to be the latest advice http://f80.bimmerpost.com/forums/sho...&postcount=340

The only thing you should have to change is 'C_Laenderkennung' to 'ECE' = '00'

Has anything changed in Euro LED too? between 57 and 59 Pszdata.

The tentative Euro2 coding at this point looks like this:

• C_Laenderkennung > ECE = 00
• C_AMR_2_c > wert_0 = 00
• C_AMR_3_c > wert_0 = 00
• CTpmsMarket > US = 01
• CPrewarnEnable > disable = 00
• CPrewarnIgnition > disable = 00
• MinRcpf > UNK_PARAM_0 = 50
• MinRcpr > UNK_PARAM_0 = 50
• CalLrPDevMax > 100kpa = 28
• CPInitRangeMax > 200kpa = 50
• UiaSetLevelPc > 25% = 19
• UiwSetLevelPc > 20% = 14
• UiwSetLevelDistMin > initwert = 0C
• CalTimeConfUiw > initwert = 0A
• CDtAmbPrewarn > initwert = 0A
• CTRefShift > nicht_aktiv = 00

If coding from PSdZData 58.x/59.x, C_Laenderkennung is the only parameter that needs to be changed.

Great job, i was apprehensive about the Euro2 since Euro1 did pretty well in autocross, i ran basically same the times with DTC OFF as Euro1.
This is definitely better, it's cutting the power so smoothly you dont even notice it.

Thank-you so much!

So this is different than the BMW EURO code MDM?

What is the difference between this and the BMW euro MDM mode?

In laymen terms, not code terms.
