What makes a later model-year M3 more desirable?

[Ruley]

The Build Journal offers a tune/software that alters the parameters of the MK20 to behave better when on the track or driving spiritedly. I don’t have any experience with the software, but it might be worth considering if it makes a good amount of difference.

Is there an easy way to tell if you have MK20 or MK60?

I have a pre-facelift 03.

MK20 will be in the passenger side drug bin. If there's nothing there then you have an MK60. Top left corner on the following pictures.

never heard of this, care to elaborate?

The car can’t really understand what’s going on on track, decides you’re on ice and only allows ~5% of brake use (which would help on actual ice). Happens with DSC on or off.

Oh wow, I bet that's a brown pants moment or worse..

First I have heard of ice mode as well... don’t recall seeing it on the old forum either

Does anyone have experience (direct or indirect) with this tune? Looks like it could be an interesting solution.

I had it on my car for a bit. Really couldn't tell the difference from stock.
