eco tec works sorta the same as vtec, but alot shittier. as we all know Vtec switches to a different lobe at whatever the rpm is that its ment to. EcoTec, moves the cam over to put lobes on different valves to get the same result. gay.

ECOTEC is the name of the engine, yes. but it does in fact have to do with variable valve timing. It's just like Nissans CVTC and the ZETEC Focus/ZX2 2.0. It continuously changes the timing to give the best power/fuel mileage.
The Ecotec 2.2-liter engine features a modular design, providing flexibility for a number of future technologies such as turbocharging, variable valve timing and direct injection-gasoline

NOOOOOOOOOOOOOOOOOOOOOOO!!!!
Variable Valve Timing and Electronic lift Control
i think that's it....it's essentially a more aggressive cam for the upper RPM range.

wrong again n00b. :stfun00b:
its: Variable valve timing and lift electronic control.

from what i understand, the ecotec does NOT have variable valve timing- here is the gm press article for that motor

sounds like it doesnt have variable timing- but it may in the future![]()
Emissions: Meeting Federal NLEV and California LEV Standards
To help meet emission standards, Ecotec's engine management system computer precisely controls the ignition and fuel injection based on feedback from the two oxygen sensors and handles on-board diagnostics.
I'm sorry i should edit that and take out the "valve" in the Variable Valve Timing.
ignition and fuel injection control= continuously changes the timing to give the best power/fuel mileage.
Which is exactly what I said it did. I dispute the ownage that was put on me.
Which is exactly what I said it did
I'm so fucking sorry. take the fucking "valve" out and damn, I'm right.
I apologize with my deepest sympanthies that YOU apparently missunderstood me.
Why the hell am I arguing with a little boy anyway? I know I am right
... and I know I don't give a fuck about your opinion. Now shove off.
