    Default Acceleration lag

    Members don't see this ad
    While driving, I notice there's a bit of a lag between the time when I depress the pedal and the car accelerates. Is this normal? Can it be adjusted?

    Not really (to both questions), at least in my experience. There IS a lag from a slow-rolling (not quite) stop, but that's pretty common in other cars too. But like I said, never experienced it "while driving".

    I believe it is a function of the drive by wire system. You never really saw that in the old mechanical linkage systems. Unless the linkage was bad I guess. Fairly annoying.

    I thought that there was a TSB to reflect the ECU. I have the same issue but have not done anything about it.

    Our 2004 Acura had the same type of lag. It is true that most of the time the old solid linkage systems had no lag. I know that my 65 Mustang with a 4 barrel carb has no lag.

    this is normal. depending on how hard and fast you push the pedal, its telling the computer what gear to put the car in to get the acceleration your looking for

    But what was the advice? A few weeks ago I decided to pass a farm vehicle on a two lane road. As soon as I pulled out, I saw a car in the distance so I hit the pedal as fast and hard as I could. There was more of a lag than I would have expected or liked, but once the car responded I was really moving and passed without a problem. My heart raced a bit too.

    IF you want the vehicle to consistently RESPOND, consistently put the pedal to the metal!

    I believe the vehicle constantly learns driving style.

    When I first bought mine, I too thought that the lag was unacceptable. Now I feel that it responds much more quickly after driving agressively for a while. Try it out, let me know if what I write makes sense.
