hi guys, after long time no contact with my friend, today had a chat with friend of mine in prtn. Try check ur car battery, whether there is a brown layer under battery terminal. Its actually inform of round shape. Iinm, normally oem battery dont come with that, it just a couple of rm, below rm 5 which available in any battery shop or even prtn sc. If i not mistaken, they call it battery terminal protector. My friend said that, maybe that can help to lessen the flicker of light when ac compressor kick coz the voltage wont drop too much when it kicks. It also help to protect the terminal from having the white sulfuric dust or what they call to the terminal.Hope this help.

About the recent recall. Its related to vvt sprocket, n if leak or crack, they change it to a new unit, n it will take only around couple of hours max compare to owv change.

Sorry not much can help nowadays. Regards.

hi guys, during leisure time, had opportunity reading many things on the net. Im not trolling nor try to do direct comparison. Just throwing some opinions.

Never been a doubt, myvi is one of the economical cars to run interm of fc, coz the car is designed to be a city car, not cruiser or tourer. But recent reading on otoreview did mentioned, myvi 1.5 auto, during town driving, approximately 80 city 20 hway, consume below 10km perlitre, n the worst is 8.8km perlitre. But on 70%hway n 30% city, it consume around 14km perlitre to 12 n even 11km perlitre,depend on speed n etc.
What has been in my mind is that never heard any complaining regarding the fc on the net. Is it because an isolated case or is it because highly acclaimed toyota@daihatsu sourced engine really gives impact on consumers?

Same when reading on forte@elantra@others, they accept it with with reason that diff segment, diff displacement n diff weight especially when somebody point out comparo it with vios or even city.

Im not saying forumers in here coz in this forum, everybody is matured enough on that matters, just previous survey on general public, they did do direct comparison on fc like saga vs myvi, persona vs vios, preve vs vios n etc without taking into account maybe due to weight differences, diff displacement, diff segment, diff type (salon@family sedan versus compact), na versus turbo charge n etc.

What urs opinion on that? Is it prtn cars really really teribble in fc meaning really big diff in margin?

tq for correction, front windshield is laminated while rear is tempered glass. Both are strong enough. Nowadays, if many notice, prtn already start using pilkington toughened glass and saint gobain sekurit glass for its car, even for saga flx. Yup, the changes start from 2009 in exora, now even saga using it. Even as budget family sedan, prtn always not to compromise its safety. Yup, i know, people will argue on passive safety features, but foundation of a car is active safety, then come passive safety to compliment it. A good passive safety car without good active safety is kinda useless coz passive safety mainly involve electronic parts which prone to failure while active safety more on structural which fixed and always there to protect u.

And maybe can check both suppliers are oem for which manufacturer. Yup, maybe some said prtn is foolish, tin milo, poor man's car, and the rnd team is stupid n etc, but they always do their best for sure. Bye.

I know this is quite boring, but just to share some info on ride n handling. But this is just basic, and it is really deep, n not as easy as changing shock absorber. Suddenly want to share it coz reading some members mentioning about gen2 is better handling than preve n somebody mentioned also about rims probs n blaming the ride n handling.

Iinm, ground clearance is the same in gen2@preve, the diff is the seating arrangement which low in gen2, n high in preve since preve derived from exora n focusing on comfort daily drive rather than prepared seat on a track day.

Dont want to touch on torsion beam setup, but more on multilink which available in waja, gen2, neo, persona n preve which related to lotus n proton ride n handling.

Basically it touches on 3 main parts which is steering, handling and ride quality. Every part divided into another 3 sub components.
For steering, it has steering effort, steering response and steering linearity.

For handling, handling straight line, handling cornering and handling lane change@stability.
For ride quality, it comprises ride quality body control, ride quality wheel control and ride comfort.
In all 5, waja is the most inferior between neo, gen2, persona and preve but still one of better in its price segment during that time. Waja suffering on ride quality, thats why when cps model came up, the tyre profile has been change a bit to improve that area.Let alone neo cps (the best in handling department as standard model) coz its 2 door warm hatch, focusing on family sedan as gen2, persona n preve.

First, talking about gen2 n persona. Gen2 did edge persona interm of handling cornering and handling lane change@stability, but even loosing in that area, persona has advantage over gen2 on ride quality body control and ride comfort. This is because, gen2 is set up to have a sportier drive while persona is focusing on improve what gen2 lost which is comfort. Even with the same platform, doesnt mean cant change the ride n handling characteristics.

While ride n handling team really had a headache, how to surpass the previous model, by changing from torsion beam setup from the donor platform, and make it multilink based. As original platform in exora, the setup is not that bad, only loose a bit on steering linearity n handling lane change to waja, but has excellent ride quality which qualify its purpose as family courier.

But,its not enough, objective is to improve it, make it better than previous ride n handling set up, and if cant, maintaining the best in each area. Must remember, still have limitation on cost coz this is not super car@ super luxury car, just a c segment car within price range of b segment car.

In balancing out all 3 aspects, they manage to mix all the best on previous setup in one package, only loose a bit, just a bit in handling lane change@stability to neo cps.

So, rest assure that preve has every best setup from previous platform. Imho, it just the comfort setting in seat ergonomic design make some feel gen2 is stable, and preve is quite tall(the height, not ground clearance) that make it feel less stable than gen2 where actually not.

Sorry for boring topic, just feel want to share something. Sorry coz some info just using layman term coz just convey some of it from what i get from my friends.

Thats all achieve by using gt radial tyre, n u know, how much better it can improve by simply changing it to superior rubber as goodyear eagle f1 or mich ps3 or even r3 favourite rubber.

Bye.

Hi guys, just to share some info on crash impact since there are some debates on what happened to the preve, many give assumption n own analysis which are quite subjective.

Really hard to judge the speed of incoming vehicles that crash into another vehicles unless the driver of the incoming vehicles still lives to tell the real story.

But i just can provide a little info that i learned and know. Cant actually argue with many masters n sifus in internet world.

First of all, when proton sending cars to idiada spain to crash test, not only to validate the data of the crash impact(which already done by using simulator n also internal crash test) which need to comply with certain body such as thatcham insurance, euroncap, adr,eec,fmvs n etc ruling, but also to validate fire @ no fire criteria of airbags.

In short, there are thresholds@minimum speed@force requirements for airbags to fire@generally known as deploy, which actually under regulations.

Normally, in g force, any impact at 7 g or more will triger the airbags which if translate into speed around 40kmh(frontal) 30kmh(side)minimum of impact. But it can be as low as 20kmh(frontal) or even 13kmh(side) if the impact coming from a solid barrier@wall or a narrow object such as tree or pole.

Actually, there are risks of airbags if deploy too early or at lower speed which even can cause fatality, and another reason is to reduce cost of repairing when safety belt is enough to protect occupant n airbags deployment aint needed. Thats why there is thatcham low speed angled barrier at 15kmh for airbags no fire criteria validation been created.

As the picture of preve been bang by another vehicle which has been rumoured as a lorry, we can see the side airbags deployed. Judging by that, and its involve 2 vehicles n and both are moving vehicles, presuming same direction,so, atleast 30kmh speed side impact(not vehicle speed, but the force) needed to deploy the side airbags. Eg, vehicle A at speed 60kmh being hit by vehicle B at speed 90kmh which moving at same direction, not opposite direction. Both vehicles speed can be lower than that or higher, but the force must be around 30kmh.

Hopefully this will give all of us a little info on crash test n airbags. Sorry not much on crash unlike many masters n sifus out there on the net. Bye

may god bless u mr fulat. My deeply wish that u recover soon...for the family, be strong, n dun give up.

hi there, dunno whether this will help. Try to check the rear mirror whether the vibration is coming from there coz there are some cases, where original thought of sound is coming from the centre of the dash, but after checking, nothing loose, but the rear view mirror is the source. When driving, try to hold the rear view mirror with hand, check whether the sound still there or not. If not, retight@securely refit the rear view mirror coz its just loose a bit, causing the vibration sound like metal clanking, but only happened at lower rpm(coz low gear, higher vibration).

But this is not 100% the solution coz sometimes, others also can cause the probs.

Added on September 1, 2012, 8:56 pmchampiro bax 2 is not really that bad during the wet.

If u really want to get better tyre on wet condition, dont look at type@tyre brand, just look up at traction rated at the tyre.

If traction rated AA, then its best for wet condition, no matter which brand. Personal favourite ps3, eagle f1 n adrenalin re 002. But still many rated AA. Hope this help.

About loudness, personally,i think silverstone kruizer ns 500@700 is quiter than champiro bax 2 but champiro offered better traction. Bye.

Abg mat, how abot the iafm operation, does it produce any sound that can protrude into the cabin?

[/quote]

the only thing i know that iafm only functioning when rpm reached 4800rpm where it change to short runner. Before that, long runner all the way. The only thing i remember it has sound like breathing sound, but its not vibrating. At low rpm, there is nothing happened in iafm unit coz it remained static in long runner mode.

Another thing, check under ur steering wheel dash whether the obd cable is securely fit in its place. If unfit properly sometimes can cause vibration.
