I have recently been looking for my iPhone or iPad if there is an app which could change the horn from 1-5 in Outgague, and which I could easily click during game play as it would be alot of help. I would like a separate app where you could click to take you for example from horn 3 to 1 without cycling through them for police chases.

The only way to use/change the horn is sending a keypress to LFS' window, and I guess that this can't be done throught another device not running Windows.

I thought that but could it be done by insim/outgague?

The thing is that InSim has this packet that may allow it. But I don't know if it's 'bindable' this way.

I'll give it a go, thanks. Do you know anyone who could make this into either an app or computer control?

Nope, let's see if anyone offer to do it. I've never used Apple products hehe

Haha that makes sence thanks for your help Whiskey, I'll see if anyone can help.
