What petrol you use for your Euro?

[EuroDude]

^^ VSC doesn't limit power nor torque. But if you are wheelspinning, it would be slower than with it off.

Na man at full throttle there is definitely a performance difference. The car feels much more aggressive at low-mid revs, even when the car has complete traction on a good surface.

My best guess is that VSC limits the electronic throttle to some extend, to avoid wheel slips and bad traction on poor road surfaces. Not sure if VSC is pre-mapped to do that, or if the sensors are too sensitive picking up even the slightest wheel speed difference, but I'm very certain something is going on there.

Unless you see that "!" symbol flash for traction control or "flash" "flash" "flash" for VSA - the VSA is not doing anything to limit power to the wheels.

But even if VSA limits the electronic throttle for a split second, you would see the /!\ flash anyway since it happens so fast.

I dont know, maybe Honda updated the VSA system a bit in the MY06 models or something.

If it was only a small performance difference then I would think twice, but with my car, there is a definite difference.

VSA ON - The car accelerates very smoothly and feels safe.
VSA OFF - The car accelerates more frugal and rough, and light on its feet.

If VSA works for a fraction of a section it will still flash. I think you are getting wheel spin if you are noticing a difference

Try a rolling start in 1st gear in the dry - say from 3000rpm to red line. See if you notice any difference in acceleration. You shouldn't.

[EuroDude]

I notice a difference in 2nd and 3rd gear as well, not just during the initial take off.

VSA really does feel like it hesitates the acceleration between say 2000rpm and 4500rpm. Not all the time, but easily around 75% of the time.

Maybe someone else here with an 06 model can verify my findings.

Yeah.I think there is something in what you say.from a standing start there seems to be a diff.it seems a little "sharper" off the mark.but i agree with yfin and aaronng when say doing 60ks drop down a gear and give it full throttle there is no diff.Maybe it's in my mind as well!!!

[BiLL|z0r]

I do agree with Eurodude and Tony as well. I know it shouldn't have any effect unless there is wheel spin/slide but it does seem diff to me as well, esp low revs and powering out of corners.

After 27,000kms trying Vortex 95, BP Premiun and Ultimate I can say that Ultimate seemed to suit the Euro and made the engine seem sweeter. Do note that I used only Vortex 95 so maybe Vortex 98 is just as good.

regarding VSA ~
Going a bit off topic from Petrol lol, Ive made a new poll thread http://www.ozhonda.com/forum/showthread.php?t=56903

So far so good with me & caltex....2nd tank already.

Cant wait to WOT my K24A.... will take it for a oil and filter change next week, then can WOT already. Once a while taking off from 1st gear, the VSA light does indeed come up, maybe launch it slightly too hard.

i've mainly used vortex 98 and ultimate,both about the same i think.

Im getting awesome fuel economy on BP ultimate 9.8L/100km in town/city driven HARD. Im impressed and smooth power also!
