You have to log 3rd or 4th gear to Accessport. The log should be done on a flat straight road from 2500 to 6500 rpm. Once you log you download the data from your Accessport to Excel as a csv file. Delete all rows except your 3rd or 4th gear pull so it is good data and save the file. You can then upload it to the Virtual Dyno software.

It is also very important that you have your car weight correct and you also need to input the size of your tires.
