You need to gather up sounds file of the car for example, A car at eg:8000rpm for at least 1 sec A car at eg:5000rpm for at least 1 sec A car at eg:2000rpm for at least 1 sec To maybe estimate if the sound is good try copy the sound and multiply the sound up to 5-10sec, if the sound mix is sudden high or low the sound clip isn't good, so find another one. I usually find those at Youtube and download them using VDownloader. To make a reference you need to open BNK, and open the XXXcar audio.bnk file and extract all and here the sounds, normally most are 5sec. The important thing is you file size MUST be smaller or same with the original one or the sound will crash when you open TDU. You can use the normal window Entertainment Sound Recorder and click properties and Converter now and the options you can see the original ones for references. After making the sound replace it to the original one using bnk editor, and play TDU. But remember to make a backup of the XXXcaraudio.bnk file.
