DSC intervene after going square 265 setup

[eacmen]

So I did reset all DSC stuff with my schwaben tool as well as reset TPM system and still have this DCS light blinking cutting power and ABSing me even in the slightest corners if I drive above 60-70. I guess next step will be ZHP rack swap and ZCP "tune" for the rack.

What exactly do you mean you reset all the DSC stuff?

Have you tried M track mode?

oh, new I mean like 1k+ miles :-)

I have new tires yes PS4.
I wonder if you can reset all above mentioned sensors with Schwaben tool.

New tires have mold release in the outer rubber for 100-150 miles. Expect less grip during that time.

The old m3forum had a long writeup on this and programming of M track mode. Any chance that info survived somewhere?

New forum has it too!

Hm... aren't you suppose to have more grip at the front with with wider front wheels?

Correct. But even square setup can understeer. Previous poster mentioned uphill esses. Weight is on the rear in that case and fronts are unloaded. If you don't scrub enough speed any car will understeer there

You can reprogram the DSC intervention with NCS, specifically to turn off understeer compensation. I had the same issue when running squared and now on track DSC only intervenes if I'm going sideways.

New tires?

Same here with 265 trofeos. DSC off was the solution.

There are many sensors inputs that go into the DSC:

• Wheel speeds
• Steering angle
• Yaw Rate
• Lateral Accel
• F/R Brake Circuit Pressure Sensors

I have never done it before but there may be calibration required to 0-out sensors that may have drifted:

If possible logging the values of the above sensors while triggering a fault or intervention may shed some light on what is going on. But keep in mind these systems were designed 20 years ago. With 20 year old tire technology. Today's street tires have significantly more grip than they did 20 years ago.

is this track driving? if so, then just turn it off and reassess
if you're getting DSC to intervene for street driving then you're probably breaking some laws/risking some lives so just back off

I remember there was a discussion on m3f, but can’t recall if it was resolved. After switching to square 265x35x18 I found that in long fast corners/turns my DSC is constantly getting pissed. I’ve been driving like these for almost a year now, but it is getting on my nerves now. I have MK60 car with a stock rack and I did reset TPM several times. I also did play with the flat ride during this time, but that did not change things much in terms of DSC getting off. Any ideas what elves to try?

Sanity check your steering angle sensor calibration. M-track mode is fantastic - worth spendng some time on.

Looks like it is more common than I expected.
