i had a bit oof f experience in both.. my brother took preve exec iafm+. meanwhile the one that i did the test drive at the SC was the CFE.

pick up wise, not much differences. since CFE is programmed to kick in when the rpm is between 2k-4k rpm. so, in terms of moving from stop, both performed pretty much the same. cruising around 80kmj-90kmj also pretty much the same. the iafm+ did the job well.. but whenever u want to take over the car in front, then u will hear the noise of the engine roaring, instead the car wasnt moving that fast compared to the roar of the engine.. the conclusion, iafm+ is enough if ur driving style more likely an unker style..

as for most of us here, we need the power to dragged the car more.. thats why we chose CFE (errr... mmm.. i havent got my car yet.. but since i already booked the CFE, i consider myself as a CFE owner hehehe)

but to be honest, the real reason why i chose the CFE is not because of the CFE. but its because of Elecltronic Stability Control. ive been through a spinning myvi. and let me tell u, its horror.. i wasnt driving fast since i know its raining.. and my tyre was just changed to a new one a few month before.. and still, it happened due to a water trap...

from my readings, the ESC could prevent the car from swaving left and right... judging from our weather, i would say, Malaysia needs to regulate a new car to comes with ESC factory fitted..

RM56 if you do in Proton Edar SC

Outside tyre shop dont have the setting for Preve just yet. They will insist they have and when you agree with it they will ask you to change the chamber screw.

Warranty void if thats the case. Please go to your nearest SC which have the balancing and alignment machine to do it.

6K km Service Bill at COSE. Total damage = RM262.00
