I'll be running nannies off. Any opinions on a starting point for tire pressures? I'm running PS4S's at 225/45/17. Temps will be in the 50's. It's been about 15 years since I last ran an autocross. Just trying to ease my way back into it. Thanks.

I don't like the car imparting input onto itself that I didn't initiate. I find with the long press the E-diff kicks on when you take on a bit of curb which is really unsettling. There are also a few corners where I used to get a bad mid corner push while trail braking which I believe is the EBD.

Did well yesterday in the event. Hands down much faster in the trac off hold. Tried 2 runs in VSC and it just killed rotation.
This is a Puretrack event. they use curbing and a well laid out course so no "sea of cones" type of event. This is a vid from someone else but good for seeing what the event is about. Awesome day. 8 runs. https://www.facebook.com/ezecena/vid...943353000/?t=0 |

The trail braking comments are interesting and something I hadn't considered.
I may play with the pedal dance. |

Also, this event was probably the most comfortable I'd been in the car all year. --kC

I've never experienced anything that would have me want to do anything more than long press to disable, but Devens and Lincoln are fairly decent surfaces. I'm also curious how just changing pads in combination with the pedal dance would eliminate ice mode, since ice mode is ABS controls "freaking out" pulsating the pedal... doesn't matter what pad you have I would think, and grippier pads would make it worse because the ABS wants the car to keep moving and not locking up? Just seems odd to me. --kC

Crossing the crown on a runway site is the most reliable way to trigger the diff for me. Sorry if that wasn't clear, the intrusion for me is the brake diff biasing. The pads and ice mode is has more to do with initial bite and release characteristics (with a pinch of adjusting technique) Factory pads bite kind of ramps up for me as pedal down, nothing-nothing-nothing-lock up. Because not enough is happening while I'm trying to brake, my brain says to push on the brakes harder, and once they start really generating friction, I'm asking for way more than I should, and undesirable behavior ensues. The ferodos start grabbing (pretty well) while my foot is still going down, so I'm less likely to overdo it on braking before the brakes start meaningfully slowing the car down. They also seem much easier to modulate for me. I also don't very frequently push the brake pedal all the way down to the floor anymore now that braking starts when I want it to, as opposed to when the pads get around to (finally start generating real friction) it.

We have a test & tune (pending weather) at our super bumpy site (Bristol), so I'm going to try the pedal dance.
I guess I need to look up how to actually do it. |
