DSC coding parameters
A lot of this has been covered in other posts (see https://www.1addicts.com/forums/show...1#post20442321 , for example) but I wanted to discuss wrt the 135i and explore what is the collective knowledge of what all these parameters actually do and what should we turn off on the track.
I think this discussion needs to be revived as the accessibility of coding these parameters just became a lot easier with Bimmergeeks ProTool (No, I am not a paid endorser...) vice needing a properly configured laptop with multiple programs and the correct datens to do this (or pay someone). Here is what Protool exposes in Standard Mode and what appears to be default from what I have learned on the interwebs: DIFF-LOCK E-Diff ON FLR Engine Power reduction (for brake overheating) ON* SST Soft Stop Braking OFF FBS Fading Comp.(adds hydraulic assist) ON* RPA Flat Tire Monitor (instead of TPMS) OFF CBC Cornering Control OFF LCL Lane Change Logic OFF ASL Trailer Stabilization OFF PRE_MSR Torque Control OFF AFS AFS Installed OFF BB_RAB Ready Alert Braking (pre-tensioning) ON* TB_BDD Brake Disk Drying ON* I don't have an LSD so the asterisked parameters above are what I disable for the track, consistent with https://www.1addicts.com/forums/show...1#post20442321. Anyone else have thoughts on this?

With that being said, there is also the thought process that as you advance on the track you should be learning how to manage things like brake temps, fluid temps (and the resulting change in pedal feel), and pad knock-back (necessitating a pre-tension before a corner). Those are things that start separating driver skill at upper levels... along with things like heel-toe, trail braking, tire management, etc. BMWS programming on these cars is street oriented and so is the ABS hardware so drivers find these functions to be lacking as they advance in driving technique. FLR - Turn off. Aftermarket pads and fluid will change the OE thresholds as to when you might experience brake fade. You should be managing brake temps by feel not by a computer algorithm. Car will go into limp mode too. FBS - Turn off. The car boosting hydraulic line pressure throughout a 20minute track session can result in an inconsistent pedal feel. You should be learning how to manage brake fade yourself by extending brake zones etc.. TB_BDD - Turn off. I am not sure what this even does. I notice nothing different in the rain. RPA - Turn on because none of us have TPMS in our track tires lol. DIFF-LOCK - Turn off if you have a mechanical diff. Off is the standard position on the 1M which comes with a visolok LSD. SST - This is not something that should not have any affect on track driving. If your car has it "on" then you can turn it off I suppose. Last edited by bbnks2; 06-21-2019 at 07:12 AM.. |

I coded what Mark did in his thread and everything went fine. I only have a 128, but I compared it to my buddies' 128 at the same autocross event and we both felt a noticeable difference in power with my nannies coded off. |

Subscribed for later when I get the BimmerGeeks Protool

There is also an emergency brake assist that for sure needs to be turned off. Track driving will trigger it all the time and it will apply extra brake force to the ABS limit every time. Super sketchy.
Leave on the E-Diff on and change rear pads often. Turn all the rest of it off is my philosophy. |
