Drivers are increasingly 'Green-Chipping' their car's engine computer to make it more environmentally friendly, but not just to gain speed, according to experts.

The attraction of chipping, as it is known, is you can modify your car's computer brain without physically altering the engine. All you have to do is alter the parameters set by the manufacturer, thereby allowing the engine to become greener. Car drivers report significant economy improvements, which directly reduce CO2 emissions as fuel use corresponds to CO2 pumped out.

Even health authorities are re-mapping ambulances to increase mpg and efficiency while transport fleets, truck and van users are all seeing massive savings from Green-chipping their engine's computer brain

Apparently, manufacturers are hampering the green credentials of many cars because their vehicles are being held back by the engine management system. Today's cars have complex engine computers that are programmed by the manufacturer so they can sell a variety of different models using the same engine.

By regulating an engine in this way, carmakers promise reduced service intervals and an increased lifespan of the engine. They focus on different power outputs when they should be pushing the environmental benefits and offering a range of "green" settings.

This is all news to me and I admit, has never heard of such a cunning plan. Have you?
