I was wondering if beamng supports any already available hardware that can make real life gauge clusters work with the game as I’m building a sim rig from scratch and having real working gauges would be an awesome feature.
Beamng does support OutGague natively. This is used more by the Live for speed community. I found this YouTube video of someone using a VW passat with outgauge and a custom programmed micro controller. There is also this product here that has support for LFS, I'm not sure if it uses the OutGague protocols but I might be best to look at Sim Racing forum posts for OutGague. Hope this helps!
