The "Pedal Dance" testing

[dave77]

Just did this today after trying for a few times in the parking lot. Love how we can do cool stuff like this with our cars. Just driving around town didn't notice any difference obviously, but glad that I can do it if I want.

Thanks for the great tip.I had no idea that this was a option.I will be using this when I get to the track this year.How do you enable the drives aids when your done racing?

Should be able to just turn it off and then back on.

Turn your car off, and then back on, and everything is back to normal.

You have to do the pedal dance every time you want it, as soon as you turn on the car.

Back at the track in a couple weeks so I thought I would actually practice the "pedal dance" in advance and commit the process to memory. Good news is "I got it" and should not have any issues activating before sessions.

Afterwards I was messing around with the buttons and found out that you can activate the VSC mode and the trac off simultaneously. Any idea what this configuration would yield??

the "track off" will disappear once you break 30kph, so it's not a "combination" per se

and in the above picture vsc is not off, i'ts just in sport mode, which is rather poor

i was losing my rear end (recoverable) when trying to trail brake last weekend at fuji speedway(just holding traction for x seconds, im going to try this next time and see if that fixes it, or its just my skill level, lol.

- Press the brake pedal 3 times. Hold it down the third time.
- Pull the hand brake 3 more times. Hold/lock the hand brake on the 3rd pull
- Press the brake pedal 2 more times.
- On the last press of the brake pedal, two yellow lights should have come on.

Mike, I found on my car the sequence is much shorter once the engine is warmed up.

Prerequisites:
- engine must be warm (coolant temp gauge at middle of "warm" area, actual temp reading IIRC must be above 170F)
- idle must be normal at ~650-750. Once the engine is warm, this can be sped up by revving the engine once or twice and the idle will settle after throttle is disengaged.

The sequence above is still the same, except I end up only doing following:

- Pump the brake pedal 3 times. Hold the brake pedal down on the 3rd press
- Pull the hand brake 3 times. Hold/lock the hand brake on the 3rd pull
- Pump the brake pedal 2 more times.
- On the last pump of the brake pedal, two yellow lights should have come on.

Short version would be 3x foot brake, 3x hand brake, ~2x foot brake.

I'll see if I have time to make a short video to document the pedal dance.

Hope this helps.

If you start the car with the e-brake up, that works

- Turn on the car. The car must be FULLY warmed up. You must do the entire sequence within 30 seconds of starting the car.
- Pull the e-brake 3 times. Hold/lock the e-brake on the 3rd pull.

I purposely used staggered brake compounds to test whether the brake dance does anything; here are my conclusions.

- The pedal dance eliminates electronic brake force distribution.
- The pedal dance also eliminates the "panic brake" function.
- I tried trail braking mid-turn with the "normal" electronic aids off, but without the pedal dance. This resulted in a spin; the car literally locked up the rear brakes. My speculation is that the car recognized the fronts locking up, and put additional force on the rear brakes. The problem here, is that I had purposely put a much lower friction pad in the back, so it kept sending more and more brake pressure to the back, until it just locked. Once it locked, it stayed locked, even though I was not stepping on the brakes.
- I tried this again a few more times. Same result.
- I then tried again, but with a rear brake bias. This time, pressing on the brakes mid-turn or trail braking always resulted in the car straightening out and/or plowing.
- With the pedal dance, I can trail brake or brake in the middle of a turn for rotation just fine, regardless of pad setup.

Moral of the story: if you're driving on a track or at an autocross, do the pedal dance! (Remember, ALL aids will be off)

All testing was done on a closed course, at the "Balcony", courtesy of Willow Springs Raceway.



*edit*

From another post:

i might have missed it durring my reading but, does the pedal dance deactivate ABS? or just the EBD? it also deactivates obviously TCS and STAB right? thanks much for your safe testing

[troek]

it leaves the ABS on. Disables everything else.

Anyone have any thoughts on using the pedal dance on snow? I've been plowing snow since yesterday since my street doesn't get plowed at all and we have well over a foot. Turning off traction control (hold for 5 seconds method) is 100% mandatory (yes, I have snow tires). Will this dance change the car for the better or worse in snow?

[7thgear]

i'd do it in the snow but too cold to activate :/

so i just makde due with the 5-second option

although i can feel the VSC kick in when i'm running over surfaces with extreme grip differences left to right.
