Off road plus will slow down your crawl in 4low, and give you a more controlled throttle response. It’s really great on steep slow climbs where you wants precise throttle. It’s also really good on steep descents if you have an auto. It just slows everything down to a molasses crawl if you want.BTW, I don't understand Offroad+ what's it do?
In 4H, it allows you to have a more snappy throttle response, turns off your ESC, and lets you use the rear locker. It’s really useful in sand, mud, or climbing snowy hills.
