The "Pedal Dance" testing

[des]

I had exactly the same experience yesterday -- repeated incidents of ice mode during a single run (probably four or five during on a 50-second course). Interesting trick, and maybe useful for a better driver than I am, but I won't be trying it again.

On stock pads.

I did have this on one run during the autocross (did 2 events with the full off mode). I thought maybe I was too hard the ABS hit back hard (caused me to have to use my sidewalls as a brake in the decreasing radius I was entering). I need more seat time with these DS2500s to figure this out for sure.

It make work on tracks and time trails, but on a fast autox course, I would never do it again.

Were said vehicles on crappy stock brake fluid per chance?

I've speculated (without confirmation) that the stock brakes have a rear bias, based on sizing, when using the same compound front and rear.

Stock.

Probably,mine was, still fair warning.

I was on the OEM tires for this so they rotate really easy as is (new track tires are on order) but when attempting to trail brake before the pedal dance, the pedal would go hard like a normal car's ABS pulsing, annoying.

So how did this affect trail braking on vs off...like how eagerly/soon/late did the car rotate? I didn't really notice anything too unusual going with all of the aids off and got the car to rotate very well on the brakes without disabling the brake biasing (didn't actually realize that was a thing until now). It felt a lot like my s14, just without the kick from the turbo.

It didn't rotate much but that was after I mistakenly put too big of a FSB on the car so a lack of rotation was a problem already

hey mike i have a quick question about this. u said that the car has to be fully warmed up but done within the first 30seconds the car turns on. im not getting this part... could u explain this to me please. thanks man!

Make sure the temp gauge (engine coolant temp) is at the "normal" position where it would be after driving the car for 15 minutes or so. Once it's there, turn the engine off, turn it back on, and then do the pedal dance, and it'll work. If the engine isn't at full operating temperature, it wont work.

How would one do this at a track event? Between sessions the engine will cool down and prevent you from doing this before a sessions begins.

It works fine as long as the car hasn't been sitting for over 3-4 hours. If you can't get the car to go into diagnostic mode that means you SHOULD NOT be on track, car should be at least partially warmed up to where the coolant gauge is over the minimum mark before any hard driving.

[Kido1986]

Idle for 5-10 minutes to warm the car up. Should be doing that before a track session anyway

If you don't mind my asking, what is this "Ice Mode" you speak of?

Price?

Let it idle for a bit before your session.

You should be warming up the entire car before driving hard, as previously mentioned...
