Uhhhh, you do know that ECOTEC is not a system like VTEC right? ECOTEC is just the brand of the engine. Like.."Northstar V8" etc. And to my knowledge there are none....

It's because they used the LSJ race casting for the 2.0 which doesn't accomodate for the VVT components. The head was originally designed for the dragstrip which has no use for the extra weight, added complexity and low-end drivability and fuel economy.

The Variable Valve Timing in the ECOTECs are not a profile change like VTec or MIVEC, the ECOTECs use cam phasing technology.
A "Vtec Controller" would change how soon the change in the cam profile would occur. Cam Phasing is constantly changing. It's completely different.
Of course like pointed out, LSJs don't have VVT, the LNF does.
The following ECOTECs have it: LNF, LE5 & LAT
