GTS MDM way too intrusive

Had the GTS on track today really pushing for the first time and noticed that the traction control is extremely intrusive.

On my e92 I coded it to Euro MDM.

Is there a US and Euro MDM in the M4/M4 GTS?

There is a euro MDM, I had it coded into my 2015 M4, I haven't had a chance to really test it, but all reports is less restrictive then the US version.

The question is does the GTS have a different MDM mode or is it the same as other US m4s?

I've read in some posts that the latest Euro mdm mode is more intrusive than in the past and not as aggressive so I don't know if you would see as much difference like in the past between Euro and US MDM. Only way to know is to get it coded

Can't drive on the track with dsc on in any form, unfortunately. Way too intrusive. Maybe use it on the first few laps to see where you're over cooking it but after that it needs to come off. at least that's what I did last time.

I did switch the Traction off. But what is nice about MDM, or at least once was, is that you could still push but it would catch you over the edge.

Not anymore. I had to turn MDM off completely at Sebring.

I got no problems to drive with MDM mode on, I even try It on a short track a few days ago. So far, Nurburgring no issue, SPA no issue, and last 3.1km short track no Issue. But for sure the first few 3.1km track laps instantly trigger more than the other tracks.

But, I just adjusted my driving and It went well no Issue, Hence no trigger of ESC. But It was also only 3-5 degrees out, Hence first few laps I struggle for gripp and thats to blame MDM kick In. After a few laps, with hot tires and me a cooler driver(not the hot-shoe as I was first laps) It was al very god, no intvention.

I guess I am driving to slow then-or to fluid. The pace I driven GTS to this date In MDM track mode has not stopp my speed around any tracks. On the other hand there are other reasons why I not driven faster, But It has nothing to do with MDM mode! Its more my lack of talent that did not put GTS faster than 2.45min at SPA my first time there In new car. MDM had nothing to do with It.




I am not trying to be contoversial here, just lay out my feeling for It. All ok, we must not experience the same things on track I guess.

I agree to use the traction control as a teacher and what I do in the beginning. However, I suppose I am not good enough to not engage it. It happens too much. I worry about burning up my CCB's and slowing me down when I come out of the turns onto the straights. I can't seem to get the power down without it engaging and much better when I turn it off but I'm sure Captain could teach me a thing or two on the track.......

This is where I find it scrubs tenths, is out of some corners. Loose is faster, with me anyway.

I agree and there is some data from drag strips (disclaimer: that I have little personal experience with), that about 10% wheel slip gives the fastest times so with my logic, the same should apply when we push the go pedal coming out of a corner?

Civic m3 here. Not sure how similar the mdm on gts is to civic m, but I turned mine off after 2-3 laps into any session just to make sure the conditions are good. Also want to the rear pads for longer use.

My timing improved with all nannies off.

My MDM allow car to slip out and have fine controlled slipangles with out MDM kicks in. There Is No way the ESC is same on vanila M4 vs GTS. BMW gone far in this car, they put loads of time to programe the braking ABS to make the most of all the grip this car give. There is some work put in to that braking system and that is different vs vanila M4. Same in ESC, It is developed for trackwork and I can slide It at angle whit no interference when In MDM mode on.

I cant say anything on how US cars are, If they are same as euro or not? I have no clu.

I know for a fact the Porsche ESP system nowdays in GT car so god you harly feel anything. On Porsche track app It show instant where and how/how long you trigger ESP. I have many friends also driving the car they say they do not trigger ESP, But when we check data we see how the system trigger several spots on track. This app also show at what angle system start to trigger. There was not more than some 0.10s of a second the Porsche ESP did slow down a solid driver at 2.6km hockenheim as I recall. ( when ESP off vs on)
My old M3 E46 CSL, well thats an old dinosaurie and ESP did trigger instant even in track mode. From then there has been big progress in GTS, at least thats my personal feeling when I now drive GTS. In some ways my porsche GT4 ESP system might been even a slightly bit better than GTS, But I now did drive GTS at short track 3.1km and I was very god in MDM mode I must say. Anybody seen the youtube film will see the car lose slightly gripp rear and still no ESC kick in.

And I bet you got solid data trace/vbox video overlay to prove your point?! I guess not! Still, I hear you, ESC will trigger and bother you on track in a vanila M4.

Well I am not tracking enough to a point where a vbox or any of those prosumer/professional timing is worth my money, yet.

I use Harrys and the track timers provided by the track organizers. All events I go to all include timing as part of the package.

And no, I don't use my phone or watch to time my laps

Something like the GTS shouldn't have nannies . . . No one learns real control anymore.

Euro MDM will catch you, but it's loose enough if you trail brake into a corner and don't know what you're doing, it will not save you. I've spun out on Euro MDM, so have a couple of other F8x guys I know.

You can spin out a US version as well. Lol, if you are over cooking it so bad nannies don't catch you. That's the problem with nannies. No-one develops real car control, subtleties of feel or really pays attention to feel and understands what the car is doing.

Gotta chuckle at trailing breaking into a corner by someone who doesn't know what they are doing . . . Are we even sure they know what trailing braking is and why is someone, much less a novice, trail braking an F80X to begin with? Did they purchase F8Xs with the rare understeer package option?
