erm,actually, cfe has more torque than cps from 1k-2k rpm, u can refer to torque graph. If u want to get optimum fuel efficiency, u shud drive below 2k rpm before the tubo unit kick in coz when it kicks, more fuel will be injected to perform complete combustion coz air ratio already diff(a lot of air coz forced induction), n fuel ratio need to balance it, so,it is known as air fuel ratio.
About feeling delay or not moving,it is due to cvt misconception by those who are not familiarize with cvt. If u get uncomfortable with cvt behavior,thats why sat button is created.
In cvt, rpm meter easily jump up n speedo is not following the rpm until it reach desire speed@designated rpm.
If u want to have feeling rpm n speedo move accordingly together, just set sat on.
To said cfe torque at rpm 1k-1999k rpm is low than cps unit,is totally wrong. 90% of torque for cps only available@3k rpm which is only 135nm@3k rpm,which cfe already reach nearly 160nm of torque as low as 1500 rpm, more than peak torque of cps 150nm at 4.5krpm.
So,hopefully this will clear the picture
Added on January 11, 2012, 8:15 amcompression ratio is not only about performance,it is also about efficiency n also lower comp ratio allow the engine to accept low octane fuel.
Normally high performance na engine has high comp ratio,and its cause them only to accept premium@high octane fuel only. Thats why type r n swift sport only can accept minimum premium fuel as ron 97 in malaysia.
Added on January 11, 2012, 8:17 amthats is also why cvvt existed in cfe,to cater low end torque from 1-2k rpm before tubo unit kick in.
