1. Use an aftermarket programmer: Several companies sell programmers specifically for Sprinter vans, which can be used to adjust the speed limiter. These typically plug into the OBDII port and allow the user to adjust the speed limiter setting.
2. Take your van to a tuner shop: A tuner shop can install a performance chip or reprogram your van's Engine Control Unit (ECU).
3. Modify your van's ECU: This involves accessing and editing the ECU's software. This is a complex and risky process, and it's not recommended unless you're comfortable with electronics and have a solid understanding of your vehicle's systems.
4. Connect a resistor to the Engine Control Unit (ECU): This is the easiest and least expensive method. However, it may not work on all Sprinter models.
- Locate the ECU. It is usually located under the driver's seat.
- Disconnect the battery. This is important to avoid any electrical damage.
- Find the wire that controls the speed limiter. It is usually a white wire with a black stripe.
- Connect a 10k ohm resistor between the speed limiter wire and the ground wire.
- Reconnect the battery and start the engine.
- Test the speed limiter. It should now be disabled.
Before any attempt, it's important to note that modifying your van's speed limiter can have legal and safety implications. In many states, it's illegal to tamper with a vehicle's speed limiter. Additionally, raising the speed limiter can increase the risk of accidents and personal injury.
