EEVblog #1181 - Car ECO OBD2 Fuel Saver SCAM!

Please help us to find bad videos. Broken or unappropriated video content?

Dave exposes the ECO (Nitro) OBD2 Fuel Saver as a complete SCAM!
They are supposed to talk to the car's ECU via the CAN bus on the OBD2 connector, but does it even do that?
Or is this Homeopathy for cars?

Bonus rant on Audiophile Audiophoolery!
