The Eco OBD2: a small device promising fuel savings of up to 15%. But does it live up to the hype? This article explores how to use the Eco OBD2 and delves into its effectiveness.
Understanding the Eco OBD2 and its Claimed Benefits
The Eco OBD2 is a compact device (7 x 2 cm) designed to be plugged into a car’s OBD2 port, a standard connector found in most vehicles manufactured after 1996 in the US and 2010 in Brazil. The device claims to modify the engine’s management map to optimize fuel consumption, leading to potential savings. It purportedly works with ethanol, gasoline, and flex-fuel vehicles.
Installing the Eco OBD2: A Step-by-Step Guide
The installation process, according to the manufacturer’s instructions, is relatively straightforward:
- Locate the OBD2 port: This is typically found under the dashboard on the driver’s side.
- Connect the Eco OBD2: Plug the device firmly into the OBD2 port.
- Turn the ignition: Turn the key to the “on” position without starting the engine. This activates the car’s electrical system.
- Press the reset button: Locate the reset button on the Eco OBD2 (if applicable) and press it for 5 seconds.
- Wait for connection: Allow 30 to 54 seconds for the device to establish communication with the car’s engine control unit (ECU).
- Start the engine: Once the connection is established, start the engine. The installation is complete.
The 200 km Adjustment Period: A Critical Step
After installation, the manufacturer recommends driving for 200 km to allow the Eco OBD2 to learn the vehicle’s specific parameters and adjust the engine map accordingly. This “learning” phase is crucial for the device to potentially achieve its claimed fuel economy improvements.
Real-World Testing: Does it Deliver on its Promises?
A test was conducted using a Hyundai HB20 1.6 16V. Fuel consumption was measured both with and without the Eco OBD2 installed. The results showed no discernible difference in fuel economy in both city and highway driving conditions.
Conclusion: Eco OBD2 Effectiveness Questioned
Despite the straightforward installation and promises of significant fuel savings, the real-world testing revealed no improvement in fuel consumption. Based on these findings, the Eco OBD2’s effectiveness is questionable. While inexpensive, it didn’t deliver on its core promise. Consumers should be wary of such devices and conduct thorough research before purchasing.
