We all know both engines have a turbo and DI. Ecoboost is WAY more than just that. Ecoboost refers more to the management of the engine than the hardware. That is why this new technology contributed to 125 new patents from Ford. To compare the Ecotec motor to the Ecoboost motor and try to say it is the same technology is simply laughable.

The Ford powertrain management strategy uses hundreds of thousands of lines of computer code and related parameters that are adjusted to optimize the engine and transmission operation. It's these processes that largely make up the EcoBoost patent contribution and make Ford's use of direct injection and turbocharging of its engines like no other automaker in the world.
"The secret to Ford's EcoBoost system isn't just the hardware – the key is in the Ford control system," said Brett Hinds, Ford Advanced Engine Design and Development manager.
To extract the level of power and efficiency achieved in an engine like the EcoBoost V-6, a remarkable level of precision is required. One example is the amount of control engineers maintain over the fuel injection system:
· The powertrain management strategy uses 10,066 adjustable parameters
· At idle, each injector releases 10.4 milligrams of fuel per injection; put in household terms, that's 1/25,000 the volume of a can of soda, or 0.2 drops of fuel
· Fuel injection pressure is continuously controlled to between 220 psi and 2150 psi
· Injection timing is adjusted up to 300 times a second
