I'm really getting tired of the Myvi's EPS - it does not gradually sharpen the steering wheel, and it is slow to respond. If you do rapid accelerations, the wheel still gives too much assist until moments later. I can't remember the amount of times when I accidentally turned too much due to not being able to anticipate the sharpness of control.

I wonder if this can be rectified over a software update?

Exactly, I could accidentally turn so much until I reach the end and knock it with a loud 'thuk'. That aside, I wonder if the stiffness problem is coming from the EPS or the ECU itself - the EPS has to receive a a speed signal from the ECU to influence the stiffness, but it could be the EPS responding late. Where is the problem coming from and how to rectify it we can never be sure unless we make enough noise to Perodua.

Yours new myvi or old myvi? Actually, for NA 1.3, 500+km is consider normal. But 350km  . You happen to have your own personal foreman? Ask him to check up for you. Possible to let outsider to check up your car rather than P2 people. They so fcuk up in every angle.

when im running my 1.5 last time, I managed to get 500km+ for RM60. Maybe, just maybe it's because been using Ron97 & V-Power regularly. Also heard that Ron95 will burn faster than ron97 or V-Power. Anyone can object or counter here?
