Hi! First of all, i dont know if i posted in the right part. If so, please move this thread.

My Volvo V50 has an "antistall" feauture. If the RPM's go below idle the car gases. i.e having way too high gear. Can someone get this to a mod for me please?

Auto clutch?

LFS automatically adds throttle when your RPM drop below idle but that doesn't mean that it'll save you from stalling when released clutch too fast.

How exactly do you mean? As said above LFS has an auto clutch feature that will not allow you to stall it, using the clutch or to high a gear at low RPM.
Even if you had to add gas at low rpm on a high gear it will still stall as theres just not enough power to bring the RPMs back above idle, and if it does its really slow.. Quicker just pressing the clutch, either by pedal or button
I had a feature on my old 'rev bouncer' that would keep the engine running when idling.. Where LFS would cut the engine after a minute or so at idle..

You can stall the XRR with autoclutch if you try hard enough
