I was wondering this same thing but more so what modes work better with different weather conditions. I know I read some older threads where members were saying best setting for the track is off/off and gravel mode, but no one has expanded into discussing different modes and how they work in different weather.

Particularly on a really rainy day, I'm wondering what would be the best mode. I know when I try with off/off and gravel mode, the car slides and loses control easier, tarmac definitely holds more grip I noticed even with off/off and wet roads, although I'm sure my shitty stock tires play a big role as well.

You have a button that says "ASC OFF", probably next to your light tilt switch. Press and hold it for ~5-10 seconds, then you should hear a beep from the dash. That is "off/off".

If you press it only once without holding it and without getting a beep, its "off/on".

Good explination. Kept all on my first two track days. By my third track day the throttle cutoff was getting obnoxious and almost dangerious so I went off/on. Last year I expermented with trail braking and your description above explains why if felt odd. Will try off/off next week.

Yep..... This guy speaks the truth. You'll realize it's time to start turning the traction nannies off when the car starts to fight your throttle inputs.

My friends had me learn the car from day 1 with off/off and in tarmac and I've enjoyed learning the car this way. The evo does slide a lot more and the steering inputs have to be a lot more smooth as well as the braking and accelerating to keep the car from being upset, but I've grown in both areas as I've tried to push the car harder and harder.
I used to autox a lot and I tried one event with the ayc brake on and I didn't like how it felt when steering. It felt unnatural so I raced the rest of the season with it off/off.
It's nice to see most guys on the forums here agree off/off is best. I was just surprised when I met guys at the track try to convince me that off was a better option and I only did one season last year so before this season began I just wanted to see some other opinions. Thanks for all your responses!

The car doesn't fight throttle inputs in the off/on mode. It individually applies the brakes to specific wheels and sends power to others to force the vehicle to PIVOT about its center, forcing the vehicle to turn in better. This is on the opposite end of the pivot spectrum normally occupied by forced oversteer to "point in/rotate".

From experience, it's more difficult to understeer while on off/on mode, and i can get on the power sooner and harder with MUCH less oversteer. I'm still experimenting with left foot braking and am convinced that off/on mode with a trained left foot braking technique will be vastly superior to the typical off/off forced oversteer "rotate" mentality that so many people have on these forums.

Side note, i havn't done enough experimenting with gravel/tarmac/snow to see which gives me faster exit speeds, but dicking around on wet pavement, i've noticed that gravel and snow causes me to understeer easier and earlier on turn in. I've since upgraded tires & changed alignment to zero toe, so this needs much more validation to say anything of value.

as far as driver training goes, i agree that off/off forces you to develop skill and pay attention to vehicle limits more. But it is of my personal opinion that i am still faster around the track in off/on mode.

The reason that Gravel and Snow cause more understeer (on pavement) at turn-in is that the center is still partially locked.

The two main differences between modes are level of maximum lock and how quickly the center opens when you lift, brake and/or turn. Since Gravel and Snow open more slowly than Tarmac (i.e., stay locked longer), the odds of the center still being partially locked at turn-in are higher in these modes, and a locked center is not what you want at turn-in on pavement.

edit: I am here ignoring the AYC because the question I'm responding to concerns turn-in and I'm assuming that the driver will not be at 25%+ throttle at turn-in

Hmm....I should try Off/On/Tarmac next time

My last experiment was Off/Off/Gravel......worst day ever, but I think it may have been because of tire pressures.

I'm repeating myself here but Tarmac Gravel & Snow also affects AYC. Tarmac being highest amount and Snow being the least.
