Choosing the Performance Meter that Works for You
Speeding is a common problem for drivers nowadays. Sometimes, you're already running on 140kph without even noticing that you're already over the speed limit until the police catches up to pull you over. It becomes even more of a problem if you don't have a functional performance meter.
Your car's performance meter gives you information on how fast you are driving based on internal accelerometers installed in your vehicle. Without a functional performance meter, you're on your way to start a traffic ticket collection. Luckily, we created this short guide for you know when to replace your meter and what performance meter to replace it with.
Indicators of a broken performance meter
- Faulty readings ? Sometimes, even if your meter says you're running on 60kph, the policeman's speedometer might give a different reading. When this happens, replace your performance meter immediately to avoid traffic hassles.
- Dysfunctional display ? If you're using a digital or graphical LCD performance meter, chances are, the LCD malfunctions before your accelerometer wears out. If you want to avoid LCD malfunctions, try buying performance meters that use cyclometers or dials for display.
Options for performance meter replacement
- Accelerator-based Performance Meters ? Standard performance meters normally use accelerators to track the car's speed. For the daily driver, this type of performance meter is ideal as it is accurate for most of the time. However, accelerometer-based performance meters can easily get altered with the car's roll motion and hard acceleration while driving.
- GPS-based Performance Meters ? This type of performance meter is more accurate than accelerometer ?based models since it uses satellite positioning to measure the distance travelled over time. Also, a good thing about GPS meters is that it is not affected by everyday driving impacts as all it needs is a communication device that will connect it to one of 24 GPS satellites orbiting the Earth.
- Computer-based Performance Meters ? A great option for a techno-savvy driver is a computer-based performance meter. An in-board computer basically tracks the car wheel's motion and generates an accurate reading of the speed. The downside for computer-supported performance meters is that it reads wheel speed based on your car's original diameter so expect inaccurate readings if you've already changed your original tires.
Regular performance meters tend to measure your speed with just enough accuracy so as to avoid speeding tickets. One thing you should consider when looking for a replacement is the display ? it must be clear, concise, and easy to understand so you'll know how fast you're speeding in just an instant.
Topnotch Tips on Performance Meter Installation
Keeping your performance meter working can save you tons of speeding tickets on the road. A functional performance meter tells you how fast your car is running. It also indicates if your gas tank is empty or not. Some meters also include a dynamometer that measures your engine's horsepower. Without these important indicators on your dashboard, you might lose sight of speed limits or just run out of gas in the middle of the nowhere. Broken performance meters usually need major repairs so it would be more convenient to buy a new one. Installing them is also fairly easy as long as you follow these steps and tips for performance meter installation.
Difficulty Level: Moderate
Tools you'll need:
- New performance meter
- Wire strippers
- Wire crimper
- Spade wire connector
- Wire splicer
- Open-ended wrenches
- Electrical tape
Step 1: Disassemble your broken performance meter with your screw drivers or wrench depending on your car's specifications.
Step 2: Once removed, you'll see a red wire connecting the current performance meter to your car's engine. Cut the red wire using wire crimpers or pliers whichever is necessary. Do this to other wires connected to the meter (usually colored black, green and white). Note: Some cars have varying wire colors. Consult your car's maintenance manual for more instructions.
Step 3: Check the fittings of the new performance meter on the existing dashboard mount. The performance meter should snugly fit on the mount to prevent dislocation.
Step 4: Splice the red wire connecting the engine to the meter using a wire splicer and then strip ? inch of the tip of the wire using a wire stripper. Do this to the black, green and white wires ? the black wire should be connected to a metal ground near the engine bay area, the green one goes to the negative terminal coil, and the white wire is connected to the instrument lights. Connect the stripped wire ends to corresponding screws on the performance meter with your spade wire connector and fasten it with electrical tape.
Step 5: Attach the performance meter in place using screwdrivers. Check if the newly installed meter works by doing a road test.
- Before working on the installation, turn off your engine for safety precautions.
- Wear rubber gloves when working on your car's wiring.
