FWIW, in case anyone runs National events and get protested. VCDS mod like these are not legal per current Street class rules.

I recently got VCDS and have been playing with some different settings (ESC off and XDS+ set to moderate are a noticeable difference). I am also really interested in what brake settings are working best. What are you guys adjusting for the brakes? I have also searched through the Obdeleven and VCDS tweaks threads without much luck on what to change.

I don't have it on hand instantly, but I already posted which route
to find the brake assist setting with VCDS somewhere on this forum.
It wasn't to complicated if you just play with or, say, browse VCDS
some minutes.

It's in Module 03 Adaptations
Hydraulic Brake Assistant
Hydraulic Brake Booster
Brake Booster

I played with Brake Booster and Hydraulic Brake Assistant today, albeit only at slow speeds and couldn't really tell much of a difference.
Standard settings for Hydraulic Brake Assistant was "4". I tried 3 and 2. Can't remember what i tried with Brake Booster.

Requires more testing.

I went into mine via Obdeleven this morning and started to make some changes. It is hard to get information on what the settings do so I guess we have to experiment.

Module 03 Adaptations
Hydraulic Brake Assistant (factory set to Normal) I changed to Not Activated

Brake Booster (factory value set to 4) changed to 5 but did not drive yet.

Hydraulic Brake Booster has a factory value of 8 and says Bias. I did not change this yet. Has anyone played with this?

I would like a slightly firmer pedal and smooth modulation (which I should have better modulation with the Hydraulic assist removed). I will report in with feedback, but anything you guys can share on which direction to adjust in would be awesome.

Ok I just got to do some driving and wanted to report back on what these changes do.

Module 03 Adaptations

This is very noticeable and allows the driver to modulate brake pressure progressively. As Breaking Badly stated, this is a must do for track or Auto X to prevent the car from apply brakes thinking your are panic stopping or activating the abs.

Brake Booster (factory value set to 4) changed to 5 but did not drive yet.
I tried this at 5 and 6 and just got a softer pedal. I went the other direction and it firmed up at 2, but I currently have it at 1 and it feels great. Better feel and nice and progressive braking force.

Hydraulic Brake Booster
has a factory value of 8 and says Offset (not Bais) This setting was very strange. I bumped it up to 10 and apply hard brakes. The car would load up with steady pressure and then after about 1 second it would feel like someone stopped the pedal. There is a surge of brake assist that was delayed and feel really bad. Like the car is recognizing what you are doing and then trying to help. I went back to 8 and let it for now.

My notes say there's a "brake overboost" in there that's active/inactive. I have it and HBA set to inactive.

Need to try the Brake Booster at 2, sounds nice, maybe lessen the initial aggressiveness of the default boost.

Nice work! You've inspired me to give it another crack today. Your description of the differences makes me think that perhaps my OBD11 changes did not even activate!

Thanks guys for bringing this back up. I had removed torque limiting and ECS, but not the XDS and braking mods. Will tinker!

Hey RM, have you seen an event actually break out VCDS cable and laptop to sustain a protest?

Set Brake Booster to 2 - a little different, in the right direction, but not enough to please. Tried "0" and it's pretty sweet. Still the annoying two stage pedal, with too much travel (would rather it be pressure sensitive) but much better.

Sec. Code 25004 for this one.

No, realistically its an honor system. And locally no one will probably care. But at a National event, or Nationals itself, you can't discount the possibility.

Thanks. I don't autox, other than the free Ford Racing School I got with purchase of my Focus ST. Was just curious.

When I tried changing the hydraulic brake assistant setting, it's asking for a security code and unfortunately 25004 didn't work.

Could you guys share the code?
Thanks in advance!
