I found this well searching around the internet. I understand everything, but I cannot find "Dist_Travelled"???

Any help?

When you open LiveLink with the sct connected to the car and to the laptop just click the icon on the top left (has a little graph on it). This will bring up the PIDs screen to choose what you want to monitor. Select the "Misc" and expand it. There should be one (of each of the following) "RPM" or something w/RPM, "Dist_Travelled", and Vehicle Speed Sensor (There is two on mine I just chose the first one from the top. Then you can choose to graph those 3 sensors. Start datalogging. Take off and I just run mine up to about 105. Once you feel like you have run the 1/4 mile you can then stop datalogging and save your run. It will be a .csv file that you can open later in Excel. It logs very frequently so its going to be a lot to scroll through but once you figure out your starting point and time you are set to calculate anything you want. IE: 60 foot, 1/8, 1/4 0-60 , 0-whatever. The dist_travelled is really your tripmeter but its logging out like 6 decimals of precision. Like 40.456832. Then you just add .2500000 or .1250000 to your start distance to figure out how far you needed to travel for the 1/4 or 1/8. Look the distance up and get the time. The time is automatically inserted in the file as well and is out 6 decimals.

That's pretty cool. The only problem I see is wheelspin. Should you spin the tires, it will throw off your distance that is used for the calculation. Still, it's pretty cool.
