Would you get better gas milage with the vsa on or off? Under normal driving conditions.

 

No difference; leave it on.

 

ON!! for normal day-to-day driving. It'll save your ass if you lose a moments concentration and slip up.

OFF. If/when you want to wring the car out, preferably in a controlled environment (AutoX, Track day, etc), or at the least an essentially deserted location.

 

Thanks for the info. I just wasn't sure if it made a diffreence or not

 

VSA, is computer helping you drive. I would guess the best reason to turn it off is if you want to be a manual man, if you skid you skid, that what VSA was made for to help by the computer applying brakes when you lose control of the steering wheel.

This had nothing to do with gas mileage, its a computer assist thing.

 

Just turn it off when you want to take off at full power.

 

as stated above vsa + fuel = not connected...

 

search also, theirs many threads in more detail.
