I guess the big reason is that the Etec still carries the FICHT stigma to me. The Opti uses the tried and true 2.5L powerhead that they vastly improved on to get much more fuel economy out of. Fuel pressure is set to 90 psi and is sent to the air injector. Air pressure is set to 80 psi. Then the fuel air mixture is sent into the combustion chamber in an air bubble which supports much better atomization of fuel. Its a great system, once you understand how it works. They also use an automotive style alternator which is much easier to replace in the event of a failure.
