# Creating your first chaser profile

In order to utilize C.H.A.S.E.R, the vehicle you wish to use it, will require a chaser profile.

You can create a C.H.A.S.E.R profile easily, [by utilizing the tool "ezchaserprofile".](https://github.com/Nep1337/ezchaserprofiler/releases/tag/ezchaserprofiler)

Remember that all units are in the Metric System, so Weight is measured in KGs not Lbs

## Using EZ Chaser profile:

Firstly, download an extract the tool, utilize the link above, or[ click here.](https://github.com/Nep1337/ezchaserprofiler/releases/tag/ezchaserprofiler)

Once extracted, open the file "tyre\_models.xml" with notepad or notepad++ and insert the same tiremodel names, as shown in your tiredata.lua

<figure><img src="/files/BInOMKRpe5XoPzm3Vk7q" alt=""><figcaption><p>same names, but in the xml file.</p></figcaption></figure>

***

Now, open the tool and visit [https://www.motormatchup.com/ ](<https://www.motormatchup.com/ >)and select the car you'd like to generate a profile for, once done, make sure you're in the catalog page (page where all details, dyno charts, etc are shown, and paste the link at the text field from the left of "Load Engine Data".<br>

<figure><img src="/files/9Rfadd8lKjJkzByfsJjP" alt=""><figcaption><p>Same URL, on software, after clicking in "Load Engine Data".</p></figcaption></figure>

***

Now, After the engine data has been loaded click "Load Vehicle Config" and select your vehdata.lua file location, on your computer. If you don't have a VPS and instead use FileZilla or other FTP service to upload files to your server, you will need to do this in your local computer, then upload the vehdata.lua to your server.

***

Now, After the engine data has been loaded and the vehdata.lua has also been loaded,\
It's time to fill the missing inputs, ***the software will only work if all parameters have been inputed***, if it has been written "W\.I, Waiting input, W\.I.E" means it needs to be filled.\
\
First: \
Type the entry name (same name as the .yft file)\
\
Meaning if the car is named *`"adder.yft"`* in the car folder, you'll type just ***`adder`***

***

Then, setup your suspension. It is exactly like the handling.meta, so:\
\
`"Suspension Force" = fSuspensionForce`\
`"Suspension Rebound" = fSuspensionReboundDamp`\
`"Suspension Compression" =fSuspensionCompDamp`\
`"ARB Strenght" = fAntiRollBarForce`\
`"ARB Distribution" = fAntiRollBarBiasFront`\
\
Alternatively, if you're unsure of the values, you can use the "RNG" section, which will generate automatically a suspension setting based of 3 presets:\
\
`"Sport", for sports cars.`\
`"Classic" for old/common cars`\
`"OR" for Off Roader cars.`\
\
After the suspension is done, click in "Set Default Diff Settings", do not worry about those, and simply leave it as it's been automatically filled.

***

Next, make sure to flag properly if the vehicle is a electric vehicle, or if you want to use launch control.\
If you wanna use launch control, make sure to type in the launch control rpm range.\
\
To decide the launch control RPM range, simply verify where the torque peak, on the torque curve viewer, use the mouse scroll to zoom in/out of the torque curve, to find the best point.

***

At last but not least, make sure to fill in the "Flywheel Weight".\
\
This controls how long it takes for the engine rpm to decay when reving with the car still or using the clutch.\
\
The more, the longer, the less, the quicker. I'd advise to use values inbetween 2.0 and 3.0

***

And that's it, simply click "Add New Entry" and you'll already be **able to utilize this car in-game!**\
\
\&#xNAN;***(Don't forget to restart the resource!)***\
\
\&#xNAN;*P.S: If any field has "None" written in it, it's because the website didn't had that info, look it up on the internet and fill it in.*
