Read the above message. It seems 1.6MT is having quite good fuel consumption.

Just curious, why Proton VVT engine has such a high rpm during idling which can contribute high fuel consumption when driving in heavy traffic condition.

Warming up is about 1200rpm.

After warming up, it is nearly 900rpm, maintain about same idling rpm at N, D or with air condition kick in.

You have upgraded your tire size, what brand?

I think you are facing the same issue just like @KennRicky. He had reported about the same in this forum few days ago. Suggest you send the message related to this issue to Official Proton Facebook to get the better advice if no one here can help you.

By the way what is your phone android version? Mine phone android version 9.0.1 just work well with head unit.

You can watch this in linked youtube video, listen to the video audio at time between 2:49 to 2:53.

Some Proton Wira or Iswara with carburetor engine may have this knocking sound if they do not retard the ignition timing when switching to RON95, especially when the engine is at low RPM and high load such as climbing up the hill.

My Iriz is using RON95, so far no knocking sound.

Your engine has knocking sound at idling or on what running condition? If the sound is really "scary", should let service center mechanic to check and confirm what is really the sound is, sometimes could be other issue that is not related to fuel octane number.

For your own trial, maybe you can try to fill up RON97 one time and see whether that "knocking" sound goes away or not.

Manufactured part will never 100% perfect in dimensions and always have production tolerances. The running-in will cater the sufficient time for those moving surfaces to make a good contact. There is YouTube video related to this topic shows "minor" metal debris found trapped in the oil filter during running-in period, this shows manufacturing and production process never can be perfect. So in my case, I choose to apply the running-in as recommended by maker.

However, it is up to individual to believe the "running-in" theory or not. Even someone car may perform poorly after few years, it is difficult to prove it is because of running-in. Because so many factors can affect the car engine performance after few years on the road, that including how we drive and maintain our car in normal days.

That is true, equipment maker always try to be conservative. Same apply to engineering, always apply safety factor in design works to counter the imperfection in material production, construction or manufacturing etc..

I feel that my Silverstone tires is making less noise now compare when they are new, or I already start to adapt to the tires noise?

Will take note of this in future and thanks for sharing this info.

You mean the TCS is activated (light up) even your tires never slip?

What is purpose of removing the "throttle controller", because they suspect it had affected the pedal throttle signal sent to EMS? is it the after market additional installed "throttle controller"?

Possible to send the car to another Proton service center that is more capable in troubleshooting and diagnosis the E&I problem?

If they know the problem and fix it straight away, that is okay. I also have same concerned like you, worry they create more problems while trying to solve the "small" problem.

If "swapping" happens, it is not about luck, it is about those people ethics in doing business.

Can't deny there are haters out there. But if the review is not true, the service center should defend their reputation and take necessary action on the reviewer or at least make further clarification on the "false" accusation.

As the car owner, I think they may know their car better than the workshop. Once they know their original part is swapped, it maybe difficult to prove, but they will lose trust and wouldn't go back to the same workshop again.

This happened to me sometimes ago, not "swapping" but also about honesty of workshop. One of my car engine overheat and sent to workshop (not service center) for top overhaul, the workshop claimed they had changed my engine cylinder head unit but I found out they never did. I knew because my original cylinder head was with some epoxy glue stains which I had used it to repair something inside engine bay. So when I got back my car and open the hood, I immediately recognized it was my original cylinder head with epoxy glue stains. I further confirmed it with my car engine photos before the overhaul (normally I will take some photos on my car including engine bay before I left the car to any workshop for repair).

I do understand top overhaul is not cheap as they need to spend time to complete the job, and also they may need to send the cylinder head for machining etc.. So I don't mind to pay the reasonable cost for labor charge and workshop machining charge etc., but making false claim or cheating the customer is really not acceptable.

16km/l, that is impressive.

With the Saga 4AT is introduced now, those who always complaint about the CVT can go for Saga 4AT now . I think that is good strategy move by Proton, now people have the choice if they dislike CVT so much.

For me, I can adapt the CVT behaviors so I still prefer CVT as the car can get seamless optimum transmission ratio for the load. Yeah, people will say can not push hard if use CVT, well I know my Iriz is not the sport car, so no reason I drive it like a sport car. If I really want to drive like a sport car, it is better I pay more and buy the latest RM300k Megane.

I think his car is EPS.

You can find out the cost here.
