Common Questions

Everything You Need to Know
About EcoFluxx

Will this work on my vehicle?
EcoFluxx is compatible with virtually all cars, trucks, and SUVs made after 1996 that use the standard OBD2 diagnostic port. This covers over 95% of vehicles currently on the road in the United States.
Why don't auto manufacturers optimize the ECU from the factory?
Automakers program ECUs conservatively to handle all weather conditions, fuel grades, and emission tests worldwide. This leaves 20–30% of fuel efficiency untapped. EcoFluxx adapts to your specific engine and driving conditions to reclaim that efficiency.
Where is the OBD2 port on my car?
The OBD2 port is located under your dashboard on the driver's side, usually near the steering column. Every vehicle made after 1996 has one. It takes less than 5 seconds to plug EcoFluxx in.
How long does it take to see results?
EcoFluxx learns your driving patterns over the first 200 miles and continuously optimizes your ECU for peak fuel efficiency. Most drivers notice improvement within the first full tank.
Is EcoFluxx safe for my engine?
Yes. EcoFluxx only communicates through your OBD2 port and makes no permanent changes to your vehicle. It operates entirely within the factory safety limits set by your manufacturer. Simply unplug it and your car returns to its original settings instantly.
What is the money-back guarantee?
EcoFluxx comes with a full 90-day money-back guarantee. If you don't see real savings at the pump, send it back for a complete refund. No hassles, no questions asked.
