Folks

On my 1.4 Sport, I have this gut feeling - unsubstantiated by empirical evidence - that the ASR dulls performance somewhat throughout the speed range, not just when accelerating away from rest. I can certainly tell the difference with ASR off when I give it some welly away from the lights - I can make the front tyres squeal in 1st and even 2nd gear. But even in 3rd, accelerating hard out of twisty bends, or overtaking, it seems to me that the car is a bit less sharp with ASR on. Has anyone else noticed this, or am I imagining it all?

It does what it says it should IMO (y)
 
Well, the ASR is certainly effective in the wet, or on greasy roads, and I would always leave it on then. However, what I am suggesting is that it may be reducing torque to the front wheels unnecessarily soon in ordinary driving.

Not really, rather accellerating quickly at below 30 mph

Must be driving slowly if you notice the difference between it being on and off as at 30mph ASR is automatically reactivated. ;)

Well, that is interesting. Are you absolutely sure about this, Beastly one? Which leaves the very pertinent question - why on earth would Fiat want to reactivate it above 30 mph on a car which hardly has enough power to invoke wheelspin at higher speeds.

Maybe its a common ASR sytem used on cars that REALLY need it... (y)
 
I'm 100% sure.
Fiat tech head that was explaining the system to us that said it.

I believe it is because when ASR is off so is the other systems stability control and EBC all that stuff. So Fiat designed the system so when your going fast enough to kill yourself the car will try stop it happening and any resulting lawsuits.
 
Well, there you are. It was all just imagination on my part, then, as I half-suspected. It goes to show how it is almost impossible to judge engine modifications by the seat of your pants, either - the car will feel faster after you fitted that induction kit or the sporty exhaust, just because you think it should. Sometimes it might even be slower :)

Thanks for the info, Beast.

Placebo effect can be huge sometimes. The amount of people who swear their Puntos are faster with a K&N when they have been proven to reduce power are testamount to it. Car sounds faster so it must be.

When the only evidence you have is what you feel then there is always going to be a bit of ambiguity as to whether it's real or not. The way I see it is that if it feels real then who cares. (y)
