Just wondered whether anyone had experience of this gizmo and is it supposed to increase power or efficiency. http://www.ebay.co.uk/itm/Renault-M...213265?hash=item415d00e251:g:4c8AAOSwHQ9WWwO7
It will confuse your ECU into thinking the fueling is off so it can up the fueling. This won't do anything other than damage the engine, CAT and other things. Sadly if its too good to be true.......it ususally is. The only plug and play map I would consider would be fastchip.nl (HENK)
If u increase power it could have fuel economy, but only if u drive on a easy way, if u keep pushing the car u ll waste allot of fuel
