Overview & Tools Needed

As a simple review of NFSHS, cars are located in the directory \Data\Cars. In this directory are subfolders for each car, for example, the CCam folder contains the Chevrolet Camaro. In each car subfolder will be a file named car.viv. VIV files are opened using a program called NFSWizard, which you can download from the Tools Needed section below.  Open a car.viv file in NFSWizard. You will see a list of about a dozen files. The car's performance is in the carp.txt, double click on it and a box similar to the one in the pic to the right will appear. This is the car's performance file, the carp.txt.  The carp.txt is divided into five sections, each section is denoted by a tab at the top of the box. Click on a different tab to move to a different section. Each page is usually divided into upper and lower halfs, this tutorial treats each vertical half seperatly. The titles of each vertical section are in bold itallic.

 In each of the sections, you will see many text fields with numbers in them. Some of them have a icon that looks like a white graph to the right of the text field, clicking on that icon will open a graph showing all of the numbers in that text field. A few of the text fields are drop down boxes, with Yes and No selections.

 This tutorial discusses each section of the carp.txt indivdually, for example, on the main tutorials page, you can see there is a link to a section of the tutorial called "Part 2: Gearing/Engine". This section would cover the Gearing/Engine section of the carp.txt. The prefered way to read this tutorial would be to read through each page, then use the "Next Page" link at the bottom of each section to go to the next section.

 As a warning, almost all measuments in the carp.txt are done in Metric, using Standard measurments instead of Metric will result in a inaccurate carp. This tutorial will denote when necessary which measurments are Metric and which are Standard.
