I already did when I installed the mod, this is the end of my cfg.txt:
OutGauge Mode 2
OutGauge Delay 1
OutGauge IP 127.0.0.1
OutGauge Port 35555
OutGauge ID 0
Prior to these there are these lines:
OutSim Mode 0
OutSim Delay 1
OutSim IP 0.0.0.0
OutSim Port 0
OutSim ID 0
Should these be edited? Anyway right now the situation is that I have the modded sounds on only when I am playing with the camera in the inside of the car. This is not a big problem, but I would love to hear the cool engine sounds on replays too.
The mod works great for me but I have one problem. The modded sounds stop when I change the camera to an outside view. There is also no modded sound in replays.
