I am wondering if there is a way to turn the VDC off and keep it off (resets when car is restarted). I think the mileage is better and I like the feel when it is off. I have searched the existing threads with no luck.
I PREFER how it feels when VDC is off. I do not need help decelerating, etc. The only thing stupid is that picture. You look (and sound) like a psychopath.
Let me guess- divorced and bitter?
Really though, how hard it is to reach down and press the button when you start the car to turn it off...
And unless you are always driving your car on the edge and causing the VDC to kick in and turn on, it shouldn't net you any MPG...And if that's the case, try slowing down and drive like a normal person and your MPG will really go up...Not sure what you mean that you don't need help decelerating, because VDC doesn't have anything to do with that...

decelerating? you think it's abs?
you don't even seem to know what vdc does...

woah there steve! who pissed in your cereal today? mc gave you an answer with an opinion and that's your way of saying thanks? you're stupid.

Re-read the OP. It was a simple question. I drive 500+ miles every week and do not like the VDC system on when I drive. It's just that simple. I would rather not turn it off every time I start the car. I do not need her telling me that what I want is stupid. As for not knowing what it is and does:
Hit ctrl-f and search for deceleration and VDC. I can also tell you that without question, the range of a tank of gas is increased with it off. If you don't know about it, maybe you should try before posting.

You are quite ignorant on what VDC actually does...None of those articles you posted had anything to do with VDC helping you decelerate your car...What VDC actually does is it applies braking to a wheel when it detects slippage while turning, so unless it's raining all the time when you drive or you are driving down the highway like it's a slalom test course everyday, VDC shouldn't even be turning on and shouldn't be affecting your gas mileage at all.
Man, the moi-le-savant attitudes in this thread is irritating.
FWIW, it has been dynoed that VDC off is best for dyno runs. There is no wheel slippage here.
And VDC/TCS are integrated systems. You guys really think you're experts about when the VDC/TCS triggers?
"Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the optimum traction has the highest priority under TCS operation."
"TCS may be activated any time the vehicle suddenly accelerates, suddenly downshifts, or is driven on a road with a varying surface friction coefficient."
And I can confirm the sluggish feel with VDC on with normal road conditions (it looks like engine throttle management is more aggressive than you guys think) - I also prefer to disable it.
I think it's time to end this thread with the facts and move on.
Traction Control System (TCS)
•TCS is standard on the 3.5SE.
•The traction control system reduces torque to the drive wheels by altering injector pulse and controlling the Electronic Throttle Control (ETC) motor. If necessary, the brakes are also pulsed via the ABS control unit and hydraulic unit to reduce slipping.
–For injector pulse and ETC functions, the ECM receives wheel slip information from the ABS control unit through the Controller Area Network (CAN) bus.
TCS operates at all speeds and limits drive-wheel slip (wheel spin) under most conditions, improving driver control of the vehicle in slippery conditions as well as on dry surfaces if throttle is over-applied.
Vehicle Dynamic Control (VDC)with TCS and ABS
•The VDC system is optional only on the 3.5SE. The system integrates ABS and TCS with additional cornering controls.
•The VDC control functions (integrated into the ABS control unit) monitor the input from steering wheel angle, vehicle speed, wheel speed, G-force and yaw rate.
•When vehicle stability is affected by road conditions or the need to make an emergency maneuver, the system helps to maintain optimum speed at each wheel.
•The system controls engine output by reducing fuel and throttle opening,and provides individual braking control for each wheel to reduce or prevent skidding.
VDC changes engine power and/or applies the brakes individually as necessary to help stabilize the vehicle in severe turning situations. VDC helps enhance performance in emergency avoidance maneuvers, helps improve vehicle directional stability, and helps provide improved control even on slippery road surfaces.

Of course you want to turn off VDC during a dyno run if you are trying to get the optimal HP readings...If the wheels do slip on the dyno drum, which I have seen many many times personally on a dyno, the computer will limit engine power output through the TCS and lower the total HP output reading on the dyno...Same with when you go the track, if you want your best times run with the TCS/VDC turned off because even if you spin, the car will be putting out maximum HP at all times instead of cutting power...
Under normal driving conditions though on dry pavement and normal driving habits, VDC and TSC will not engage and the car will drive like it does if it was turned off...it will not affect the cars MPG unless it turns on by one of the wheels slipping, which shouldn't happen under normal conditions...If that were true, I guess my car would get 30+ MPG on the highway because I already get 28-29MPG with it turned on ALL THE TIME...
I am looking for information on a programming option to change the function of the VDC switch from momentary/toggle to maintained- such as the CD radio and aux buttons. If you do not understand what I am talking about, get in your car and drive to 25 MPH now take your foot off of the accelerator and coast to 10. Now turn the VDC off and do it again. Repeat if necessary. The difference is the feel I am talking about. It is there all the time, regardless of what other posters want to say. I would prefer this to "hey, just rip the fuse out." If you don't do this, stop wasting everyones time with your opinions about what "should be" or your "best guess" about how it should work. I am sure this attribute may be assigned to the switch, just not sure if it is user definable. This was a factory forced "option" that was part of the deal when I bought the car (3.5).
