hi,
only  check engine lit up?
what about cvt and esc warning light?

the only advice i can give to those involve in heavy traffic n stop n go situation, if dont need to speed beyond 60kmh, just rev not more than 1.6k rpm cuz between 1-1.6k rpm, it is being programmed to facilitate slow movement, n useful for heavy traffic.

N for slow cruising or less traffic, more than 60kmh but not more than 90kmh. Rev beyond 1.6k rpm, but not more than 1.9k rpm. Not only to avoid turbo from operating, but also cvt will change it character to become more agressive start from 2k rpm n above.

Speed below 90kmh, aerodynamic of the car dont play big part, thats why knowing how to handle the throttle can help a bit on fc. Speed beyond 90kmh, aerodynamic start playing it part, thats why even rev beyond 2k rpm, it wont hurt much coz aero helping out in reducing the fc n the throttle position@pressure is maintain at a point for a long time, there is no need extra energy which needed in stop n go situation coz not only aero, also rolling also help the engine from work hard to move the car.

The energy needed to move the car when stagnant is higher than when its already rolling. That is why, letting the car roll on itself after stop at traffic light@complete stop before throttling, does help in reducing fc. Not only due to rolling, it also can avoid overev(can also affect fc even not that much) due to clutch action.

This is eco indicator on ur own :-). Hopefully this help.

Well I believe when someone try something better, they will hardly look back.
I doubt many people will want to try that everytime they ignite the engine, its a good try none the less.

thanks mat79 for ur advice.. will try to remember this on my daily driving as i always stuck in jam.. 

Mat, I always find your posting informative. Presumably you have some involvement with Proton.  Most of us based on experience with other cars. 3 or 4 version of lyn preve later, anybody who does not go throught the numerous versions and pages will miss out on your input. Prevoc or Prevec easier to find. I suspect the air intake route for the Preve and worst still for the Exora does affect the fuel consumption. (Will experiment with CAI later) Not that much better than an open pod in stop and go in traffic. Coupled with the long ratio  between 4 (after the super close 1234] and 567 where the tcu program goes quickly to 7, the cfe has torque but it ain't a turbo diesel and 20kg translating to 18kg on wheel isn't a heck of a lot torque to lug 1.4 tonnes around town or up a mountain. I can't expect good consumption from a 5 speed manual tranny if if I slot straight to 5 after the 2nd gear in moving traffic.

What antenna did you change to? By the way what is the headlamp projector, high beam and fog light bulb type for preve?

of course the same one. changed @ SC.

u changed antenna cos the reception is not good?

u changed antenna cos the reception is not good?

Morning every fellows!
After ECU update, i feel like my FC quite okay. exact half tank = half bar can go up to 232KM.
which you calculate like this : half tank ( RM42/232KM = RM0.18 )

I change the antenna because of i am using it on my Waja. Yet i read some comment that Preve radio reception is bad

Have to compare FC between NA and FI Preve. How much worst is the FC for the FI Preve or similar? I recall Waja Campro FC also not that good compared to 4G18 Waja.

I find radio reception good when on highway or outside KL in other town. In KL, I select RDS and AF off. The moment on highway, I select on.

I found that the RDS & AF never works for me. I have to manually tune in.

Hi everyone. Gonna get my Preve soon. I'm totally new to the auto world. Just wanna ask how does Champiro tyre do as compared to Goodyear?? Bumpy rides? Thanks in advance.

Bro, which sc you went for ecu update?

Yeap, only check engine lit up, I send it to mutiara damansara SC today, they checked the wiring of ECU and upgrade ECU TCU again...3 hours ofter i collect my car, same problem happened again..SUPER FRUSTRATED NOW!!

I notice more thing during the previous breakdown, the feeling is like suddenly the gear automatically change from D to N halfway driving..stop the car completely, press pedal again, the gear stuck at gear 1..failed to change to gear 2...

could it be gearbox problem?

SENT TO SC 3 TIMES...CANNOT SOLVE THE PROBLEM.......ON FIRE NOW..

i think for confort ride, the best at entry lvl is Conti CC5 and Yoko Cdrive 2, if you have budget, Michelin also good. which Goodyear you compare with? i was searching about tyre last year, workman from tyre shop told Goodyear Direction 5 have good traction but very noisy~

i think u get almost the same problem with me...
but mine cvt warning lit first.. then esc followed by check engine after cabut and pasang balik battery terminal..
before that i want to ask u somthing, your preve si cvt cfe right?

the symptom happen to me, the car sluggish is extremely rough..
very light foot on padel minyak seems dont help the sluggish..
car feels sooo lazy and rpm wont shoot more than 2k if im not mistaken...

i sent the car to mutiara damansara, same as you almost 3 hour.. start the car and the warning light still appear.. then they suggest me to go to dealer at subang (kg melayu subang) got KFC there..
they check for about 2 to 3 hour i take my car, start the car no more warning light, but need to change start stop button (need to order for about 1 week) oni..  now for about 2 month maybe.. no more that problem..
