VCDS – Acceleration Measurement - Section 14-A
When you have one or more Measuring Blocks or Advanced Measuring Values with speed
(km/h) in it, clicking on [Acceleration] will bring up the Acceleration Measurement window,
which allows you to enter start and stop speeds and distances. After entering the values
you want to measure, click [Start]. Next, do your acceleration runs in a safe and legal
location. The "clock" will start counting when the car starts to accelerate. When complete,
click on [Save] to save a copy of your results to your C:\Ross-Tech\VCDS\Logs directory.
Use [Done, Go Back] to return to the Measuring Blocks or Advanced Measuring Values
screen.
Note: The +/- tolerance shown is based on the sample rate of the data selected. Use a
single measuring group and check the Options screen for tips on obtaining the fastest
possible sample rate. Our testing at a dragstrip yielded results within the tolerance.
Obviously, changes like overall tire diameter can greatly affect the results.
Warning!
If you wish to observe real-time data while driving the car, please use a second person!
Let one drive while the other observes the data, making sure the person holding the PC is
not in front of an active airbag!
