canadaRS1.0: not if skills are not there to do it safely enough to not risk oneself, totaling car and even more so - others on roads, and if it's not cheap beater car but instead only one and daily driven at that, of whatever gender owner is. VSC is compromise, but imho not at best limit/level, there should be another intermediate step between it and fully of, or it should be tunable imho.

Hahaha!! Your not driving hard enough!! Go out on a back road and give your brakes a good squeeze but not to the point ABS kicks in and it will down shift. Only time its annoying is when a dumb kid runs out infront of you and it downshifts and you look like a ass. However I normally throw it in "manual" and downshift to help slow down before the corner when im driving spirted.

Likewise. However -


After a FULL Eneos flush + replacement, my slush box, for the first time and ever since, auto down shifts and rev matches noticeably and loudly, on sudden braking.

Hmm, my 2015 FR-S 6AT auto downshifts with rev matching in manual mode every time at around 1500 RPM if I don't do it myself. Also, if you go below 7mph, in 2nd, it auto downshifts to 1st every time unless you're in snow mode.

Yup, we call it "transition control" because it is really designed to alter the power output based on slip percentage. We can then also bias it based on steering angle input which gives you--slip angle (provided you countersteer).

People make it sound like if you turn off the traction control your call will start sliding everywhere.

I have owned the car now for 1 year (don't do winter driving) and I always drive with my traction off on dry days and the car doesn't slide unless i really floor it like a crazy person and even then sometimes it doesn't slide or give out. Maybe because it's a 2015 model.

The only time i turn on VSC is if it's light rain.

If it heavy, then i keep all the traction controls on.

But seriously, on dry days, you can drive with everything off and be fine.

What makes it more fun trying to sort this out is that Automatics have two Sport buttons. One for traction and one for aggressive shift points.

@Mr.Impreza : In dry days, yes, imho safe enough with vsc off. With not deliberately trying drifting/power oversteer, careful driving and being able to correct if needed with countersteering, full tc/vsc off imho is safe enough even in winter and rain.

My point - to still have some safeguards to correct biggest mistakes if one deliberately/intentionally TRIES to drift/oversteer, to not spun out even if mistaken too much, when still learning/when skills are not there on reflex level yet. To have vsc kick in at bigger slip angles then at stock, not having it completely off or interrupting even at very slight slips.

Nice to hear, that it seems to be possible with EcuTek racerom, thanks @xjohnx & @moto-mike . Going to search more info on that, as sounds like something i wished.

That's how I have it as well, except when it's raining. Then I leave all the nannies on.

Nannies aren't there for when driving is easy. They're there for that "oh shit" moment where you've got a too-quick-to-think aggressive correction to make.

You might have a lot of HPDE time and be 100% comfortable with everything off. I'd wager most people, even if they have some notion intellectually of how to keep their car under control, and may have done so under controlled circumstances, will completely fail in an emergency situation.

I live in Alaska where it rains 90% of the year.
I probably have to keep the nannies on at all times, but i like to live on the dangerous side sometimes so i click them off for fun!

In my opinion, no reason to turn the nannies off when driving on public roads. Too many uncontrolled variables that you wouldn't see on a track. I wouldn't want to be cruising along at 50, only to need to slam the brakes and swerve, then spin out because someone pulled out in front of me.

From my experience even on very wet or icy grip-less roads VSC on gave enough time to correct in even worst conditions. I wouldn't be so sure that absolutely all nannies needs to be on for those 'oh-snap' moments. It still doesn't help much with learning those limits by driver or rather may give wrong reflexes of 'i can keep flooring accel, or swing it too fast, as nannies will cut accel and correct slip anyway'. Yes, switching it off completely will let learn .. but without any safeguards left at all instead of making them more slack.

i agree it must be a 2015 thing because they changed the suspension and i'm in a automatic ...on dry days i drive in vsc sport and i push the heck out the car through corners and i never feel any of the assists kick in and slow the car down..i'm not even sure how much harder to push it that would require me to turn off trac

maybe downshift to 1st and do a scandinavian flick and floor it or yank on the handbrake ...vsc sports seems to be just right
