Traction Control Modification

Hello all,

I love my new S2k, I've put over 7K on it in the 3ish months I've been driving it! I do have one complaint though, the traction control seems to be a bit oversensative.

Don't get me wrong here, I am a firm believer that most traction control systems are better designed than the driver behind them. That said, I keep finding my self in the situation of carving through a big beautiful sweeper at 70ish% of my traction threshold, gram by gram rolling on the throttle headed for a perfect apex, when a small surface imperfection sets off the traction controll and BAM! the chassis gets more upset than a caged monkey next to a bannana bucket, and my turn is ruined.

I don't want to turn it off because if I make a big mistake I want it there to bail me out. Is there anyway to vary its sensitivity or adjust the threshold required to activate it?

As far as traction control, I use my right foot and let the torsen diff do the rest. We don't need no stinkin' buttons...

IMHO, if you make a "big" mistake no traction control system is going to save you...

To answer your question, I can't see any way that Honda would leave the control of something as sensitive as TCS in the hands of the consumer. I think you are stuck with it just the way it is(unless there is a malfunction). Just be happy that you have an off switch, meant for the track I'm sure.

I have a CR with VSC and when I drive any road that has serious twisties, I turn it off. I came from a '04 S2k to the CR so I'm used to driving without it. Try on a road you know well until you get used to driving without it. Then try increasing your speed a bit and do a couple of runs. After a while, you'lll know how the car reacts and what it feels like when it starts to get to the High Pucker Factor area.

Shaddow, are you on summer tires? On a warm day with Star Specs, I can drive pretty damn aggressively without much VSC intrusion. Keep things smooth, and as long as the road surface is good, it shouldn't bother you much. If there are bumps & imperfections in the road, don't ask for what the car can't give you.

TSC makes for really bad drivers. They just mash the throttle all the time because TSC keeps them from losing traction. Its probably a neccesity with all these 2-ton 400hp boats on the road lately but for a lightweight 4 banger. Nah. Turn it off when you want to drive fast. leave it on otherwise.

if one or more tires are undersized, or approaching the end of their lifespans, it could make the traction control oversensitive.

it's using the wheel speed sensors to regulate whether or not it should be active, and tires worn more on the rear vs. the front would make the system more active than usual.

a reflash to the most current data supplied by Honda may also make it less sensitive, but I'm not aware that there has been a change in the logic that controls the system.

just sayin'

That second one was harsh, true, but harsh.

I like the concept behind that picture, but that those are AP2v1 wheels which means it's a '04-05. '04-05's don't have VSA...

Somebody needs to find a different picture for that poster.

Maybe there arent any! It does work that well! In all seriousness, was VSA 06+ or 08+?

Edmunds says "The 2006 Honda S2000 receives electronic drive-by-wire throttle control and stability control".

VSA is a safety tool and should be treated as such. It is like abs, seatbelts, and airbags. If you do not understand it and use it improperly then it becomes useless and possibly dangerous. Seatbelts, when worn improperly, can injure you badly. ABS can't magically stop you on a dime but it will threshold brake way better than I can even on my best day. Sit too close to it and an air bag deploying can do you some serious damage including broken bones.

My point is a driver should be realistic and learn how to use his safety equipment properly and not just ignore it.

OP: seems unlikely Honda would make it adjustable. Start with the obvious stuff like checking for strange tire wear, problems in the suspension (are the spacers they ship the car with still in the springs? They shouldn't be. Leaking/failing shock), get a good alignment from a serious alignment shop... The usual suspects.

I don't rely on VSA to bail me out of a really big mistake. I use it as an early warning system. Had I not had it on for the December EOM run it might have been me instead of that other guy in the video turned backwards when the Snake turned out to be slicker than any of us expected. Instead I got a couple of warnings so I could slow us all down.

Very easy way to tell how close your tires are at being the same dim.
Jack up one side of the car and take a tape measure and see what the circumference is, it doesn't matter what it is as long as both the front and rear tires are the same or close to the same circumference. The farther apart the circumference is between the front and back tires the sooner the VSA activates.
When I went to 245/45-17 rear tires the VSA worked even when I was taking it easy(I had it off most of the time), that's one more reason I went with the 235/45-17 front tires(all is good now).

An '06+ car WITH VSA would never have ended up like that.

Thanks TT, now I'm nervous with my "03". Fortunately we don't have many trees like that here in South Texas.

Hey, they're AP2V1 wheels! Those cars didn't have VSA...the caption is wrong!

(hehe....but really, maybe the dude just put an old set of wheels on his car)

Those trees kept the car from going further down the side of the mountain. That appears to have been taken in the "S"s at the Dragon.

Those look like AP2 version 1 wheels, which would make it an '04 or '05 without VSA.

Even on the track VSA work perfectly. It blink couple times during lapping. I have it on and drive it home rather than off and tow it back.

I had an '05 with no VSA and now have an '06 with VSA.

I would not turn that VSA off for anything. I love it. It is a bit harder on rear brake pads though.

Even F1 cars are DBW with VSA.
