EcoOBD2 devices are designed to enhance your vehicle’s fuel efficiency and reduce emissions by optimizing engine control unit (ECU) settings. These plug-and-drive devices have gained popularity as a simple way to achieve fuel savings. However, there might be situations where you need to reset your EcoOBD2 chip tuning box. Whether you’re experiencing issues, moving the device to another vehicle, or simply want to revert to your car’s original settings, understanding how to reset your EcoOBD2 is essential.
This guide will walk you through the process of resetting your EcoOBD2 device, ensuring you can confidently manage your car’s fuel efficiency settings.
Understanding the EcoOBD2 Chip Tuning Box
Before diving into the reset process, let’s briefly revisit what an EcoOBD2 chip tuning box is and how it functions. The EcoOBD2 is a plug-and-play device that connects to your car’s OBD2 port. This port is a standard interface in most vehicles manufactured from 1996 onwards.
Locating the OBD2 Connector: The OBD2 port is typically found underneath the dashboard on the driver’s side of your vehicle. Refer to the diagram above for common locations.
Once plugged in, the EcoOBD2 device reads data from your car’s ECU. It then remaps the ECU settings over time, based on your driving habits, to optimize fuel consumption and lower emissions. This process is designed to be non-permanent and reversible, distinguishing it from more invasive ECU remapping methods.
Why Would You Need to Reset Your EcoOBD2?
Several scenarios might necessitate resetting your EcoOBD2 device:
- Troubleshooting Issues: If you suspect the EcoOBD2 is malfunctioning or causing unexpected vehicle behavior, resetting can be a troubleshooting step.
- Transferring to a New Vehicle: EcoOBD2 devices are vehicle-specific to some extent as they adapt to driving habits. When moving it to a different car, a reset can help it recalibrate for the new vehicle.
- Reverting to Factory Settings: If you wish to return your car’s ECU to its original factory settings, removing and resetting the EcoOBD2 is the way to go.
- Preparing for Vehicle Service: Some users prefer to remove any aftermarket tuning devices before taking their car for servicing at a dealership.
Step-by-Step Guide: How to Reset Your EcoOBD2
The reset process for an EcoOBD2 chip tuning box is generally straightforward. Here’s a step-by-step guide based on the common installation and operation procedures for these devices:
-
Turn Off the Ignition: Ensure your car’s ignition is completely off and the key is removed from the ignition. This is crucial for safely disconnecting or resetting any electronic device in your vehicle.
-
Locate the EcoOBD2 Device: Find the EcoOBD2 chip tuning box plugged into your car’s OBD2 port, usually located under the dashboard on the driver’s side.
-
Unplug the EcoOBD2 Device: Gently but firmly unplug the EcoOBD2 device from the OBD2 connector. There are no clips or locks typically, so it should pull straight out.
-
Wait for a Few Minutes: After unplugging the device, wait for approximately 5-10 minutes. This allows any residual power to dissipate and ensures a complete reset of the device’s temporary memory. While not explicitly stated in the original article, this is a common practice for resetting electronic devices to ensure a clean state.
-
Press the Reset Button (If Applicable): Some EcoOBD2 models come with a physical reset button. If your device has one, locate it (it’s usually a small, recessed button). Press and hold the reset button for about 5 seconds. This action will clear any stored configurations within the device. Note: Not all EcoOBD2 devices have a reset button. If you don’t see one, proceed to the next step.
-
Reconnect the EcoOBD2 Device (Optional): If your goal was simply to reset and continue using the EcoOBD2, you can now reconnect it to the OBD2 port.
-
Start Your Vehicle: Insert the key into the ignition and turn it to the first stage without starting the engine for about 30 seconds. Then, start the engine. This allows the EcoOBD2 to re-establish communication with the ECU.
-
Recalibration Drive: After resetting and reconnecting, the EcoOBD2 will need to recalibrate to your vehicle and driving habits. Drive for approximately 200 km (150 miles) to allow the device to adjust and optimize fuel efficiency settings again.
What Happens After Resetting?
Resetting your EcoOBD2 device essentially returns it to its initial state, as if it were being installed for the first time.
- Clears Temporary Memory: Any learned driving habits and fuel optimization maps stored temporarily in the device are cleared.
- Reverts to Default Settings: The device goes back to its default configuration.
- Requires Recalibration: Upon reconnection, it will begin the process of learning your driving style and re-optimizing ECU settings from scratch.
Reinstallation and Calibration After Reset
If you have reset your EcoOBD2 and plan to continue using it, the reinstallation and calibration process is similar to the initial setup:
- Plug into OBD2 Port: Ensure the ignition is off and plug the EcoOBD2 back into your car’s OBD2 port.
- Ignition On (No Start): Turn the ignition to the first stage (accessory mode) for about 30 seconds to allow the device to communicate with the ECU.
- Start Engine: Start your car’s engine.
- Drive and Recalibrate: Drive as you normally would. The EcoOBD2 will automatically begin to recognize your vehicle and driving habits over the next 200 km (150 miles), adjusting itself for optimal fuel saving.
OBD2 Compatibility and Important Notes
Remember that EcoOBD2 devices are designed for vehicles with OBD2 ports, which are standard in most cars sold after:
- USA: January 1, 1996
- European Union: January 1, 2001 (for gasoline engines), January 1, 2003 (for diesel engines)
Important Considerations:
- Safety: EcoOBD2 devices are designed to work within the safe tolerances of your engine and ECU. Resetting and reinstalling them should not cause harm to your vehicle when done correctly.
- User Manual: Always refer to the user manual that came with your specific EcoOBD2 device for any model-specific reset instructions or recommendations.
- Professional Advice: If you experience persistent issues with your EcoOBD2 or are unsure about any step, consult a qualified mechanic or the device manufacturer for assistance.
By following these steps, you can effectively reset your EcoOBD2 chip tuning box, whether for troubleshooting, transferring to a new vehicle, or reverting to your car’s original settings. This simple process ensures you remain in control of your vehicle’s fuel efficiency enhancements.
