at Shah Alam..just google Proton COE

Their FB and Google customer reviews are shocking!!

Anyone tried anything to improve fuel comsumption?
Does it even work?
1)Fuel Shark that connects to the smoke plug?
2)Magnets?
3)Nitro OBD2 Performance chip tuning that connects to ECU plug?
4)Add better grounding cables?
5)Add voltage stabilizer?

Personally I think 4&5 has some merits to it, especially when aircond compressor turns on/off, it suddenly draws so much power that even my head light and radio volume dim down and engine harder to rev...but I also heard SC said it will deep fried your ECU unit?

Any pro/Sifu can recommend? or have tried? Will it void warranty even if it's just an addon?

And if the battery died/disconnect, the ECU will reset? what will happen to the car?

Saw a minor scratch on my car. Anybody tried Ezy Touch Up Paint before? Is it effective?

whatever u did this car still bad FC ... i think proton hopeless, problem still alot , fc bad for all proton cars ...

the button itself is not getting lit up. will take a look at the meter cluster later thanks bro

I think this is the follow me home feature... the handbook should show how to turn it off. Take a look at it.


For 1 to 3, is a scam. Don't fall for that.

For 4, usually new car don't need additional grounding unless you wanna improve the sound system with woofer and amplifier, to check if you need a good grounding it can be checked with a multimeter to see if the resistance is high from the contact point back to the battery. These grounding have a lot to learn... you may refer to video in the spoiler for your understanding.


For 5, in my opinion, Voltage stabilizer don't help much in improving fuel consumption of the car, mostly are just some placebo effect.

What problem you facing?

This car is not made a good FC car like Bezza to begin with... but heck, go on and check on Bezza thread also finds user reporting bad FC of 11km/L or 300km for full tank despite their tank is slightly smaller but there are also some who manage to hit good FC too, guess the user and route covered played important role in getting a good FC as well.

For now I'm hitting 14 hours drive, 480km distance travelled with 1 bar left (no refill fuel light lit yet)
70% City and 30 highway with about total 2 hours bumper to bumper jam in this trip.

In my opinion the Persona FC is not the best in its class compared to those EEV, but it wasn't terrible, the FC is average given the weight of the car. My 200kg lighter Myvi 1.3 MT doing just only about 7% better compared to Persona. meanwhile my 1.3 MT Iswara is struggling to hit 400km with 32L of fuel, this Persona can easily hit 450KM or more with 32L of fuel at same route travelled.

I don't think he owns a Persona at the first place.

hi guys, can i ask what type of car phone mount u guys are using now? i am using the one that sticks to the windshield but it kind of blocks my view when i am driving. i googled and there is a type that clips to your aircond but i think since our aircond at the centre is vertical i dont think that works too unless i want to clip it to the aircond at the driver side.

less than RM5 from Mr DIY

simple and does the job

Hi. I tried. But to be honest. It feels the same. Regret going to Thelp second SC in KJ. They did reset and clutch adaptation which I forgot to mention.


The Reverse gear issue is still there.

Went to SC in Kota damansara today. The guy overconfidentaly explained to me that it is due to brake problem and we need to do bleeding 😬😠

Thanks. I tried. But it's still the same. I think I need to few SC to rectify the issue.

Anyone know how to play videos while driving. Any tricks or something. Tq tq tq

For complicated issue better send to HQ COSE for checking..

mine also got same issue like u last time when just receive the car..give it some time after 500+ km issue not noticeable already

Can't compare with Myvi, milo tin car tend to get driver crushed by engine any time of the day involved in major accident

I looked at the book already not able to found info about this feature..last time collect the car remember my SA got inform me on this but i forgot d..what is the function of this follow me home feature yea?

anyone know where is the button for follow me home features located in the car?

Eventhough they don't entertain your enquiry, they still read this thread

Me too. The resident car techie in the showroom briefed me thoroughly b4 sending me away in my new car..but i guess the follow me home feature /instructions failed to follow me home.was too excited then.
