in GEN CPS and Waja CPS

both engine equip with VIM at low end, CPS at high end.
I don't see "make low end suffer and make fuel economy worse" in it.

Is CPS high performance engine? Maybe but not as high as vtec. I don't see any recent Honda 1.6litre car with vtec. Maybe compared with City/Jazz 1.5 Vtec?
CPS never meant to be fuel economical engine but with the VIM, it does gives some improvement.

Thus it isn't fail. Its just not good enough compared to the mature vvt-i or dual vvt-i.

Do you own a Waja CPS?
CPS for better performance, VIM for better fuel economy.

From the specs, the Waja CPS comes with CPS+VIM. So it isn't a fuel economical engine? Theoritically, it is compared to CamTakPro. Thus this engine beat CamTakPro in term of power and fuel efficiency, I don't see anything wrong with it.
Remember, it is an improved version compared to CamTakPro. Not compared to vvt-i and vtech.

I was driving waja 4G18P, it gave me 19cent/km for town driving.
Based on sphiroth driving method with high rev etc, 16cent/km certainly a good improvement. No?

The best I get on Waja 4G18P was 16cent/km, that was pure highway cruising.......
