honestly, there's a bunch of stuff in the handheld that you won't use, but everything's very very easy to figure out. If you change to off road X, you go in to the Rear O2 Sensor menu, and click "off". If you change gears, you go into the Gear Ratio menu, and put in what gears you have. If you change sizes of tires, you look up the diameter on the manufacturer's website, and go into the tire size menu, and put that number in. The basics are really easy, I just wouldn't go in and mess with the air fuel and timing adjustments unless you know what you're doing. |
