Hey guys I'm still very new to the aston world so I'm hoping one of you guys can help me out. I noticed yesterday that the car doesn't sound as loud or feels as sharp as before when it was in sport mode. It runs as if it was in normal mode. So I did some hard pulls and drive around more this morning and it definitely sounds and feels like sport mode is not engaging. Is there any diag that I can run to see if it is really the case? I'm gonna take it to the dealer this weekend but it's annoying the hell out of me right now so just want to see if I can do anything to calm me down . Thanks in advance gents.

 

As far as I know "sport" only remaps the throttle response (more gas with less pedal pressure), revs higher before upshifting in auto, or prevents automatic upshifts at redline if using the paddles. No change to the noise or suspension or anything else on older DB9s.

I don't bother with it anymore because it really doesn't do much.

 

Hi yvr thanks for the input. I thought on older models (mine is 05 btw), sport mode will remap the throttle for sharper response and also opens up the flaps in the exhaust. I did noticed the car being a tad louder when sport mode is on. I maybe wrong. Right now, with sport on I'm not feeling the more responsive throttle regardless of the exhaust. Thanks again!

 

More info on your DB9 please...what year? Automatic or manual trans?

My understand is that sport mode remaps throttle as well in the Aston but in some other cases sport mode does stiffen up the suspension like in Ferrari the sport and Corsa settings change mapping, traction control, differential settings and suspension parameters.

 

Hi Sunir, mine is 05' with auto. From what I understand, the older ones only change the throttle mapping and open exhaust flaps when in sport mode. In later ones (dunno when it starts) the suspension gets stiffer as well as the throttle mapping and exhaust flaps. Not sure how the traction control gets set in sport mode for later and older ones.

 

Just pull out fuse 22, it will then at least sound a lot faster and make you feel better!

 

Or, unplug the vaccum lines at the valve and plug them. Accomplishes the same thing as removing fuse 22.
