I doubt any add on can actually decrease the FC. Of course, taking out the spare tyres, reduce extra "baggage" (go gym), will help also....ever so slightly. My meter almost always show 7+l/100km but when avg the filled petrol, 8+l/100km, so if you read from meter, I suggest you go the manual way of fill petrol full tank avg to calc.

PE seems to excel and somehow save petrol and higher speed (rpm) coz its optimal torque come in pretty late. So lower than 2.5rpm at lower speed is not really an optimal rpm reading for FC savings unlike other car makes with higher torque and lower weight ratio (aka City, vios, etc).

That is solved by LCP actually. The effect of LCP is bringing forward the torque acceleration. I've always mentioned, I could close gaps faster, accelerate much faster at low end.......one of key changes is LCP somehow switch the gear earlier than before.

Before LCP, from standstill, it takes quite a while for auto to change gear to 2 and then 3. The slow gear change actually hold the car back instead of giving it more low end power as it does not change when needed (manual has no such issue). This increased FC besides slowing acceleration speed once the low gear runs out of breath before it changes.

After LCP, when accelerating from standstill, the gear smoothly changes when its reaching a certain speed and so on to gear 3 without a hiccup unlike the stock ride. No pulling back....just smooth acceleration all the way to high speed if needed. That is why I'm in the opinion that LCP is A MUST for PE AUTO TRANNY.

Initially when I installed LCP, I keep overpressing of accelerator pedal coz used to tekan kuat sikit for car to move. After a week or so, my right foot just naturally tekan softer sikit and the car just zoom smoothly to higher speed. Vibration and sound of engine is noticeably louder and I've complained abt it, thus LCP has cons as well.

In the end, the pro of everyday driving with MUCH increased and smoother low end torque acceleration for auto tranny is just too great vs the cons of increased vibration and engine noise just......disappeared (get used to it liao). As mentioned many times, I would have abandon PE if not for the LCP mod to address the weakness of PE auto tranny gear change and low end acceleration.

Go for either Works Engineering (that's what I'm currently using), abt RM350 or so OR go for Mytheo (that's what I'm supposed to install....mistaking the high price, regret a bit), abt RM550.

If you're in Klang Valley, call Drex up. Most of our PE Works installed by him. Later only find out Mytheo price only RM550 including installation (abt 1-2 years ago), not RM700++ as I initially thought...

Mytheo has harmonic dampener, similar to our stock, a better option if you willing to part more cash for it. Works still ok tho but hear that vibration a tiny bit stronger than Mytheo.

And DON"T DIY unless you know what you're doing. You would not want your CP to drop of and the belt worn our prematurely or even drop off if you don't know how to install correctly. Engine will stop running ooi. For normal mechanic tho, its plug and play, easy.

When you're using auto tranny, MUST GO INSTALL LCP. Our auto on wheel hp only 70++ vs manual 90++. Quite a huge difference thus LCP is a must to address auto tranny low end torque major weakness.
