Disabling Traction Control (TC) and Vehicle Stability Control (VSC) Completely

Hoping this is the truth.

Yes it is. It's in the owner's manual.

I wouldn't be surprised if regulations in some countries prohibit complete disengagement of the VSC for any car driven on the street.

I'm not worried about this.

So far I've read dozen's of review by professional drivers and journalists and I have never read any criticism of the "nanny features" making the car less enjoyable. In fact, they've gone the other direction by saying that the pure handling and seemingly invisible electronics make it so excellent.

If you are an aspiring Formula D driver and want to disable these systems.. then go ahead. As for me, I'm fine with a little oversight to keep me from hip checking a telephone pole.

IF it works as the 350z system does, ANY left foot braking will deactivate the throttle.
By light pressure they mean resting your foot on the pedal enough to activate the brake lights.
I Detest this system, but unfortunately understand why they feel the need to include it. Software is the only way to deactivate the 350 system

Journos get early access to cars, but it is far-fetched to think the "handlers" at the early Fuji press days were pulling fuses from the cars. When you had trouble disengaging the systems, did the Subaru reps at the event have any explanation to offer?

PS Your username made me think of this little guy...

Thanks for the compliments. That is the cutest "Gor ghzeei laaa" ive seen. Now where's Ultraman when u need him to save the day? Really puts a smile on my face. But the nickname is actually in reference to my weekend "little monster". I'm sure you can figure out what car is it. Hehe.

As for turning of the VSC, TC thingy, don't get me wrong, i'm sure you can still do the same stuff u see Ken and Chris does on youtube. U probably see the drift angles is because they are using lots of speed and weight transfer to initiate the drift and overcome the side effects on the electronic aids. Bottom line u still can slide it with the electronics still working.

While on the other hand, i'm only mucking around on a car park where u can't even 2nd gear. With so much traction plus and there is not much power going through the autobox and with the electronic aids kicking its abit annoying. (I can't dump the clutch in an auto to over come the lack of power hehehe).

Like i said again, when u follow the instructions as per the manuals to turn everything off, it feels like the electronic aids treshold/ activeness is lowerd to 20% of it's abilities.

Being a road car i reckon it's only fair for the manufactures to setup the car like that.

My other logic for the electronic aids to be partially active in the background to help trick the torsen rear diff to mimic a clutch pack lsd.

If u guys are familiar with torsen diffs, they don't work if one of the wheels are spinning too much compared to the other (or when 1 wheel is in the air).

All i can say is the FT86 is a pretty good street car that still allows u to have fun.
But if u want to go further than the streets, unfortunately one still needs a dedicated setup up car to get the best out of it.

My 2 cents.

Its the truth in theory and as per manuals.


But my concern and feedback is the VSC and TC is still there working in the back ground. I still find that Continental cars setup their ESP systemes better (as in more fun to drive b4 they intervene drastically) than the Japs.

Re: Brake override

If brake override is there, how can we heel-toe?

I'm fairly sure that I heard heel-toe throttle blipping in some of the videos.

I reckon the Brake Overide System shouldn't be an issue.
As long as one doesn't ride on the brakes for too long it wont intervene (i'm thinking of counting one thousand and one mentally).

I reckon most modern car have them and in the normal course of driving an automatic while left foot braking, so far i've not encountered the ecus completely cutting the power while on a spirited drive in a Peugeot 308 Turbo.

While mucking around with the BRZ through slaloms which we setup, didn't realise the ecus intervening at all while LFB through the excercise to maintain speed and to help the front to tuck in.

On a side note for those worried about my initial comments about sliding this baby, the handbrakes are pretty good hehehehe.
I will leave the rest to your imaginations.

For the record i'm a self confessed cyber racer and keyboard warrior.
hehe Cheers.

Brake Override System may be a North American thing, I'm not entirely sure. I wouldn't think that it would defeatable either (through user input anyway), given it's a safety feature like ABS or EBFD. Actually, I don't know if EBFD is defeatable or not, that's a good question.

That's the full procedure for turning off vsc in an is250/350. Same style vsc/tc system.. It's probably the same system you can "disable" it completely by holding the trac light for over 3 seconds... But, it's not fully disabled. The rx-8 also uses a similar system.

It it's anything like the rx-8 system, it re-engages once abs gets active.

I too, would like to know. I'm surprised there hasn't been more concern about this. Not being able to heel toe would absolutely be a deal breaker for me, in addition to not being able to fully disable TC/VSC.

[hNt]

aren't most of the journalists praising the fact this this car allows the driver to fully disengage VSC/TC? i remember watching a video of one of the reviewers mentioning the freedom to do so

I was just thinking the same thing.

That accelerator scandal is a bunch of BS. Lawyers can go to hell.
