Have just returned from the MMM & Music weekend at Lincoln. 2 dealers were selling these devices.
One consisted basically of a pair of magnets placed around the fuel inlet pipe near to the metering unit.
The other was selling a box with 2 wires that merely connected the the vehicle battery and it pulces the ECU into boosting efficiency and ecconomy. The claims were incredable and very difficult to believe, the box however did have a LED on it to tell that it was connected to a battery.
Has anyone tried such device and did / does it work as claimed?
