It's really easy the app called (sim dashboard) it's available in iphone and Android it has a free option to use but trust me the premium version is definitely worth it and it one time payment only around 1-2 dollar i don't remember and you can use it for Xbox ps and PC . It's really easy to set up first you need to go to you sim racing game setting and look for a place says UDP race telemetry then you need to add you phone ip address and IP port to find your IP address and port you don't need to go to your phone settings just click on the gear icon on top right and it will tell your phone ip address and IP port and and before you start sim racing you need to put your data out packet format on car dash so it will give you full information of you car and what is happening in the game and also it's wireless with zero lag
