I find that I get off the line much faster with ASR off...infact ASR zaps a seriously large amount of power out of the engine. Mite just be me though*-)

Technical accelleration
I don't know the exact workings (i'm no asr expert), but obviously asr is limiting your power so the wheels do not spin as much, if you can drive well then you can do a much better job by limiting your right foot appropriately.
When changing gears and in lower gears ie. coming off roundabouts it can hold back too much power unnecessarily. Alot of Citroen C2 Vts owners get annoyed as even though it can be turned off on their car it still kicks in under hard acceleration in the lower gears.
This is my understanding, I used to know better how it worked but I can't remember from the top of my head.
Nearly all asr systems piggy back the abs system as they take the readings from the abs wheel sensors, i.e if one driven wheel is turning much quicker than the other under power it backs the power off. Dont need it on my 1.2 active though.

OK. So basically if it's good conditions swith it off if you want a quicker/fun drive, if it's wet keep it on right?
I keep mine on all the time but I think I'll play around a bit and see if it makes a difference. I guess my tyre life will decrease though
Yea thats pretty much it! Although tbh its not the best traction control system in the world.
Mines on all the time I don't really turn it off, i forget about it most of the time.
Yeah but you can easily wheelspin a 1.2 though.Nearly all asr systems piggy back the abs system as they take the readings from the abs wheel sensors, i.e if one driven wheel is turning much quicker than the other under power it backs the power off. Dont need it on my 1.2 active though.
after i had my remap done the guy from red dot drove it to demonstrate how much the car changes. Turned ASR off and omg the car was amazing!
Though when i was braking the other day the back of my car was swirving side to side with ASR off... hmmz

i think ABS is standard and just works on the speed and how much you put your foot down on the brakes. ASR turned off with loads of torque is scary but fun on the right track.
I've just read bits of this, sorry if this has been mentioned already.
ASR is anti slip or traction control as mentioned.
Ffoxy it sounds to me like there is something up with yours. When mine kicks in the light flashes on the speedo (it does quite often with my right foot)
ASR works by: a) if one wheel is spinning faster than the other it will apply the brake on that wheel to reduce rpm.
b) if both wheels are spinning faster than the road speed then the system will cut power until traction can be regained.
Its there to help in wet/damp/greasy conditions.
It is seperate from the stability control systems so it shouldnt effect oversteer when the ASR is off. However, as the front wheels can loose traction watch for understeer round bends, islands etc.
Unless its dry i'd leave it on!
Tym,
ABS has nothing to do with speed directly. If the wheels begin to lock up the ABS system will pulse the brake pressure on the locking wheel to prevent the wheel from locking, helping you to stop in the shortest distance and maintain control.
See, all simple really.
Venom boy, its ASR disconnected not deactivated.

lol, quiet you. I realised after I'd posted but no one spotted it.
He he, sorry. You got proof for all those claims in your signature .

Thanks AlanHod... Puntokris mentioned the display doing something when ASR activates... I dont see Jack ****e happening... makes me wonder, despite the light on the switch, is my ASR permanently on or permanently Off?
I will report back after a wet day and some spirited driving with my "light" On and Off.
When the asr kicks in, an orange symbol on the dash illuminates, you need to be spinning the wheels up though, and obviously because the asr is intermittent then the orange bulb will be flashing. When you activate or deactivate the asr, it will tell you on you on your digital display

Indeed, most is on here. It's for others to prove I wasn't the first

No problem, just glad to be of help. Not sure what your car is doing. Usually if theres a fault the light on the speedo is constantly on. When the system is active and it cuts in to control wheelspin it flashes.
Shouldn't need a wet road, just nail it the lower gears from slow speeds and it should kick in. Or increase revs to peak torque and dump the clutch (not advisable though, unless you dont mind clutch replacements
Although ABS is meant to keep the car controllable and steady under hard breaking as well as keeping the braking distance a short as possible (except on gravel) different versions will keep it more or less stable under breaking.
BTW ASR and ESP are to different applications although doing similar things.

A little(ok a lot) about ASR,SC,TC,ESP and all the other nicknames for traction control.
In order for the car to detect loss of traction it needs some sensors. These come in various different forms and determine how the car is behaving, and what the driver is trying to do. Yaw sensors, gyros, wheel-speed detectors and accelerometers are the most common sensors found in SC systems. In addition, information ranging from steering and pedal position, engine speed and gear selection is used to determine driver inputs.
When the SC system determines that loss of traction is occurring, it acts using the braking and engine management controls (and in some cars even the steering system) to put the car back on track. The system reacts according to a set of preset criteria depending on the nature of the loss of traction, which can include spinning wheels or slides.
Traction control is used to reduce drive loss through spinning wheels. This can occur when driving on slippery surfaces, or when accelerating hard (usually in first gear from a stand still). Traction control reacts by applying the brakes to the spinning wheel and this forces the drive to be diverted to the wheel(s) with the best grip. Traction control usually only operates below a certain speed.
There are two different types of slide understear and overstear. SC systems react to these situations by applying the brakes to individual wheels, and reduce engine torque when appropriate to keep the car on line. During an understeer situation, torque is reduced and the resulting forwards weight transfer is usually enough to regain control, if this is not sufficient to bring the vehicle back in line, individual rear brakes will be applied. When oversteer is occurring, brake force is applied to one of the front wheels, which acts as pivot to bring the car back on line. In general, the brakes are only applied to the wheels which are likely to have the most grip.
Incase u wanted to know.
No ABS just stops the wheels from skidding by applying the brakes on and off faster than a person can.
ASR uses the torque as a first priority for traction regain while ESP uses brakes first, Therefore(IMO) making ASR better and more safe.

Spot on!! Basically what i was saying but in alot more detail. (I couldnt be bothered to type an essay
)But, i was sure TC doesnt just apply brakes, when both wheels are spinning it is capable of backing of power/torque to regain the traction. Im sure thats what we were taught at uni.
