More than anything, I think a lot of the discussion has moved to the fb discussion groups. The track/race/drift/autox E82 group on there has a lot of good information being shared and a lot of guys pushing this chassis to the limit.
Your comment about the SpecE90 guys made me remember to check that fb group because
Phloozy had asked those guys about the issue as well. There are a handful of the SpecE90 guys dealing with this and they seem to have collectively realized that the throttle cut only happens when you get into the ABS while braking.
In my mind, that closed the loop on my experience with coding sport brakes to my car. When I first installed the larger front brakes from the F30 I was getting the throttle cut way more often which was the reason I wanted to code sport brakes and see exactly what changed. I'm more convinced than ever that the sport brake option adjusts the DSC pressure models so that the ABS system comes on appropriately for the larger front brakes and shift in bias.

Realistically, the sport brake coding is just a band-aid. The potential for the issue still exists, there is just a higher threshold before it could happen. If you're putting 135i/335i/F30 front brakes on your 128, definitely do the coding.
