But they do. Try pressing "L" in-game for vehicle telemetry, or go into cabin view for the tacho. edit: or is it the feature where the engine is throttled after a certain RPM value is reached, causing it to 'bounce' off the limiter? This is either a case of Zappy can't read, or you can't articulate yourself. I'm going for both :s
Yeah, the bumping nan-nan-nan-nan sound would be cool to have, now they just limit the rpm to an one value.
