Partially agree. Mod will not necessary increase FC nor will it reduce FC without incurring a cost somewhere. I can safely conclude the LCP mod DOES NOT increase my FC, still stay the same BUT with much faster gear change and increased torque and low to mid-end. Like Zen mentioned before, it does not increased HP or even torque from nothing....it just push the higher torque that usually comes from mid-range to the low end.

End result is a lose of power at high end, minor increased of vibration and noise (all cons) but great increased on low-mid end pickup and the great satisfaction of NOT allowing the darn turtles and gagas from jumping my queue in the jam. The cons might stop someone from modding it but with PE great setback of low-end torque, its an extremely useful mod and the pro will greatly outweight the cons overtime.

Don't look down on those satisfaction feeling coz it contribute to stress and driving enjoyment. These factors now makes me love driving PE (except for the FC).......without the LCP, I've been cursing all along and quite embarrassed abt its low end pickup when my wife refused to drive it complaining its pickup is like turtle (not the myvi....the real living turtle). Now even my wife commented the car pickup is a good and quite ok with driving it occasionally although its low end pickup is nowhere near my 06 city.

Cannot compared to city also because city is lighter also lah. And the cvt is much better. Also, either get power from the low end and sacrifice top end or power at top end sacrifice low end. Our stock car is using 4-1 which is also why our low end is sacrificed. Again, it is very dependent on which road you are frequent in. Yes, I get a lot better fc in city after modding to 4-2-1 but the fc in highway become higher. But then also, I dun think any stock persona running highways will complain fc bad.

I run 70% highway daily but still complain fc bad wor

Not because eating too much BKT with CKT meh?

My 2 cents, PE seems to get optimum torque at abt 100km/h ~ 120km/h as opposed to standard 80~90km/h due to our engine torque vs car weight performance ratio.

So I believe if you run 80-90+km/h at highway with PE, you'll actually get higher FC vs those running at 100~120km/h. Anything above that is gonna start makan minyak as well. For any other standard car, probably cruising at 90km/h will get lower FC instead. So our PE a bit special on highway run.

Also for those weighting LCP cons of lower high end torque.....how many times you used the speed of 150km/h and above (that's high end speed for me) vs the huge number of times you used it at low end.....I would say 1 to 1000 in favour of low end usage of torque. Of course if you like to race LONG distance a lot and win....you should forgo LCP mod.

nope, should be based on rpm..haha. manual and auto diff ratio
mine optimum rpm 2.5k around 80-90kmh and 4k around 140km...last time i tried 140kmh non stop from kl to kuala kangsar and comes back....decelerating and accelerating abit abit only..full tank..can lasted me 440km..then it blink.haha..i also tried 160kmh all the way..at terengganu new highway..fc so bad, rpm already 5k..half tank only 160km..
other than that...high fc..

1full tank = 50liter right? Everytime i refill my petrol 35-38liter max although the meter fuel almost reach E. Where are the leftover 15l gone? Or my fuel meter something wrong.

Hahaha. Ini gajah in the car.
Yes yes. Super agree. My fuel drop faster when driving at 90. 110 is best. Maybe you can consider changing ur LCP to mytheology. Haha, if I decided to change to R3 LCP lah XD
I get more poor fc at 2.5k rpm compared to 3-3.2k rpm when cruising at highway wor. Other than that no comment.

Yuh. You have about 10~15L reserve in the tank when the arrow reaches close to E.

lol 38liter=around 400km.   Reserve in the tank 10~15l still can go 150km~200km.
