hi all, im greatly happy that most of the probs have been iron out. I know its still not perfect yet, but from what i heard they work extra hard to make it perfect. Thank u all for ur comments n report especially those who r do it through the right channel coz any rectification need a formal report n it takes time to rectify it.

Hopefully all will be even better this year. My wish that drb will sell the manual version for malaysia for the new project. The f01 engine, still need time to test, dunno whether can be feasible within this year, hopefully it can. Punch n getrag also give full support on the future development. Best regards n happy new year, even its a bit late. Bye.

is it the driver's windows? Try to calibrate. Its in the owner's manual. About the sound, try to notify which one is the cvt sound n which one is the wind sound, it may help u to find out the source. Maybe some of the sound u heard is actually cvt sound.

hi all,the easiest way when u r on a slope is that treat it like manual car. When u stop at slope, u can put the gear to neutral n engage handbrake. When u want to move, slot to d, wait until the clutch engage without pressing footbrake. U actually can feel the car want to move forward. Or the easiest, monitor the rpm meter, if the rpm meter move at 1k rpm n above a bit without throttle, then disengage handbrake n apply throttle. It wont roll down.

On the other note if during stop n go on slope when u just using ur footbrake, u can slowly disengage footbrake to ensure the clutch is closed@disengaged then apply throttle promptly. If u fully disengage the footbrake it will roll down a bit b4 clutch is closed. if u disengage the footbrake very fast, dont worry,just apply throttle. Dont afraid to apply throttle around 1.5k rpm at slope cause it will start to move the car slowly, not promptly like auto car. If u r driving up on parking lot, u realise that the rpm is raise higher, but the car slowly move compare to auto cars. Its not that it doesnt have the power, but it is one of the strategy implemented for safety reason so that u wont bump to other car infront or maybe the side barrier cause if cvt doesnt have that strategy, it will be too fast. Thats why untill 1.6k rpm, the car start moving a bit slow b4 it release its full torque, in order to facilitate when driving in parking lot, stop n go traffic,over a hump n when driving around housing area where u need to drive slow. It is easier to over rev cvt equip car, n when the engine has so much torque at lower rpm, if release it for instance, it may endanger the driver n people around it. As additional safety measure,it also equip with traction control.

I had to agree with dares on hill assist separately, but it will incurr cost. But cvt supply by punch already has hill assist but it is not as efficient as hill assist in many dual clutch gearbox equip cars, but it has.

Bye.

b4 i forget, preve comes with esp and traction control. Both are diff.

:-),please wear seatbelt no matter if it is only for short distance only. There's reason why euro n ancap give out point for seatbelt reminder. Remember, 70% is on seatbelt, airbag is only around 30% interm of effectiveness. There's no point of pretensioner n load limiter if u dont wear seatbelt.

Just my friendly advice. Be safe.

hi all, erm, not really clear bout what happened, but from complete stop to move during uphill, the cvt will let the engine to rev higher than normal to avoid sudden stall coz punch cvt is clutch based, same as when u r driving uphill from complete stop to move, u need to rev a bit more before releasing the clutch. The judder u feel maybe due to clutch drag and also an effect from low ratio pulley. Normally d mode, it will try to move to high ratio as soonest possible to aid fuel efficiency.

Since there r some torque reduction happened to ease slow moving motion, rather than instant power(quite dangerous if this happened which be like a rubberband), its one of the strategies so that it will avoid any unwanted sudden acceleration due to overrev. It is easier to overrev cvt based car coz not totally link to the gear ratio like normal manual gbox. While normal at used torque converter to control torque, this using clutch action n drive by wire sensor. Traction cntrl alsoo being used to prevent the wheel from spinning faster than it shud be.

I dunno whether this will help u, but checking during servicing wont do any harm.

For speaker vibration, i think maybe need to refit back the door panel(for front doors).

For suspension sound at back, i think its the fitting of top mount of the suspension isnt at its spot, causing the touching action. Normally, loosen up all the screws n refitting back will solve the problems.

Haish, assembly line workers tido ke.....passion is important in doing a job, even passion is one of the important elements being stress out before, still some neglected it. Its ur pride n honour to assembly urs truly car maker, be proud of it. I know, maybe the salary isnt high enough, but be patient, if we do it right, i,Allah, in the future, it will be better.

Salam.

hi milky, normally they only erase trouble code if the engine@cvt sign appear when there is no fault with the car, maybe due to some glitches between sensors@ bugs. Normally they just reset it to default. But in ur case, u r having some problems, and they shud investigate the fault by referring to the trouble code. Ask them also to check the ecu connector and bracket. I'm not sure whther they r reflashing@just reset the ecu using padt. If reflash, they have to use laptop.

Please send to any prtn@eon branch for futher checking, not authorised dealer coz they normally dont have the faclities or enough expertise on trouble code.

On bosch hu, previously there are 2 oem for prtn, bosch(blaunpunkt) n clarion, but mainly is clarion. So, they actually try to use bosch coz many like gen2, savvy, persona, exora n saga using clarion, so, try something diff n great bargain offer by bosch since they r also supplying the esp, tc,abs, ebd sytems on preve.

U r right about clutch based cvt versus torque converter cvt. Same as single clutch(amt), dual clutch at versus torque conv at, which torque conv based still the smoothest operator among all.

When developing cfe n especially iafm+ variant which derived from cfe development, one of the way to make the engine efficient is to reduce@minimise powerloss through optimising operating temperature n using clutch based cvt besides other things such as 32bit ecu n torque based where as still many other manufacturers still opt for 16bit ecu to reduce cost especially on low end variant n na engine. There r still some soft turbo equip cars using 16 bit ecu. Less powerloss, more efficient n will translate better fc.

But since cvt based gbox make it easier to overrev than normal at, it seems the feedback from consumers, even its better than previous engine, but still not something to beat.

So, i think, if any prtn staff hear this, maybe try to do what other manufacturer do right now, power of mind, by using econ indicator. It does prove it manage to make the fc more efficient coz drivers' right foot is well control, as famously quote, fc is depend on right foot. I hope that they can come out with that in future product.

If any has driven any campro, campro iafm@cps engine based, it takes time to reach normal operating temperature compare to cfe n iafm+ during morning start. I heard also punch is continue doing their rnd in software dept to make the clutch work as efficient as any torque conv based. Hope fully they continue to release latest update on cvt adaptation which they r doing it for the hatch version.

But i hope that everybody remember that preve is a heavy car. Iafm+ couple with a manual version for saga,is actually better than cvt counterpart on overall performance, but for preve, between manual n cvt iafm+, cvt has an edge due to infinite ratio, so, the gbox easier to adapt it ratio with weight n etc, but for manual, u need to keep it at strategic powerband before shifting.

Jerking@rocking is exhibit at low speed, but it will be less through times, but still there. Hopefully punch will provide special solution, i think on hardware part to make it as good as torque conv. I heard honda n nissan, will coming out with cvt clutch based in the future.

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.

7 speed protronic isnt real gear ratio, its just software based ratio to give acceleration feeling@normal feeling of normal auto n the best thing even its software based, it give u the control to the gear ur self unless u overrev it or under rev it, it wud shift uppward n downward on its own to protect the gearbox.. Whether in cfe@iafm+ cvt, in full cvt mode.the ratio n gear can be said as infinite, but of course, it has min n max ratio. Punch can set even 20 speed cvt, but using paddle shift, it wud be ridiculous.

Thats why i just mentioned the rpm coz for cvt, we control the rpm of the engine, n the cvt will search suitable ratio to match with the rev.thats why, uf u rev fast at 3k rpm, the rpm stay stagnat at 3k, but the speed rise from 0-140kmh+-. So, there is no close ratio or long ratio between cvt, only when u change into full manual mode, then, the cvt been given fixed ratio through software.

Experiment with cai? :-), just remember, to change it back when sending for service. Erm, to say the air intake is the worst, i think its not bad coz everything has been calculated precisely, not just by trial n error method. It jsut for any car manufacturer, there r something they need to adhere n abide for many reasons. Thats why even standard porshe, mercedes n even beemer, can be modified to be better performance, is that showing the weakness of their rnd@engineering? Nope, the oe way is diff compare to tuners route.

Let say ecu tuning, mostly it involve af ratio an it just done based on dyno, not on the road for tuners, but for oe engineers, setting up ecu involve everything even the diameter of the exhaust is taken into account to set the perimetres. All setting not in dyno, but in real world, involve hard n cold weather, diff fuel, diff weight, diff route, diff road n etc. Remember, oe tuning take into account comfort, safety, longevity, reliability, servicability, environmental rules, power, n etc. While tuners searching for highest power they can get, it doesnt matter at which rpm, at which cost@at which rules coz no rules they need to follow, but not for oe.

For air intake, not only diameter, length, material, filter size n material, the route, postion, everything has been calculated precisely with safety aspect, performance, reliability, cost n etc.

Im just a layman, but if needed more info, u really need to meet them, u will be amaze on how is the big diff, between engineers, technicians n tuners. It only takes one mechanic to change the air intake to bigger one@better one from shelf, but it takes more than 20 engineers to think n designing the air intake to match with engine needs n etc.

try to use mode that easy to revert back to original for easier claim for warranty in the future.

Of course, its normal to any man want to modified their cars, even ferrari owners also like to modified their prancing horse. :-).

I only can tell u one thing, when choosing to equip cfe cvt preve whether with 6 @ 7 speed software based ratio, it seems for them(the engineers involve), 7 suit preve pretty well compare to 6 since its lighter than exora. But if they decide for upcoming variant with manual 6 speed, it will be the best :-). N r3 preve iafm+ easily outpaced cfe on track, he...he...

:-), for track, yes with 6 speed manual, but on the road, too many carbon that will hurt the environment :-),it will be banned. But who knows in the future for s2000, but need atleast 5 years homogolation rules, by then, i think, there will a newer engine. R3 is more focusing on na racing development than turbo charged one. Until now, r3 s2000 supercharge replica been put on halt. I dunno whether drb will release it or just scap it. Pity the r3 team.

that's the real s2000 which engine is illegal to be on road. What i mentioned earlier was r3 s2000 replica which using 1.6 cps supercharged which already ready for launching, but heard being halt n maybe discard by drb. What a waste. Even its not really saleable due to price, but it was a piece of engineering to showcase our own local motorsport division capability to produce something exciting that is road legal. But, thats a past thing by the way. Just hoping for a better future product. Dont let me down drb.

off topic. Really sad when some blamming prtn for their underspec n overprice car nowadays. While only cbu(which isnt any under cept agreement coz some under sept agreement did get 30% wave) is being tax 30% more, where others which is not from japan company can give more with better pricing. The cost of ap only incur if there r buying ap from other source coz whether they dont get the ap from g@not enough ap provided to them by g. But they cant buy@ap from g, g provide ap for them. They only can buy ap from other ap holders which is actually illegal, but that is what happened over here. The 10k cost since 2012, isnt really a cost coz it will refund back to them when ap fully abolished by 2015.

By continue blamming prtn, this will make the japs continue to supply us with underspec n overprice car.haissshhhh, sorry for the rant. Easy for japs coz no need to console malaysian consumer since we console ourselves n help in giving excuses for them. Easy job for them....sorry again.

speedworks, already done a good job. But as i say, oem tuning compare to 3rd party tuning, still diff coz for oe tuners like r3, the must ensure its reliability coz the standard warranty still intact n many things need to adhere due to emmision control, even its euro 2 in malaysia. N if u ask speedworks, rather they meeting jpj euro 2 emmision on modded engine, i dunno whether they did it under euro 2 emmision control or not.

About b16 n b18, isnt that honda's engines? I dun think even honda still using that engine in stock mod for their cars nowadays due to emmision regulation. Unless u r talking about not so new ivtec soch engine 1.5-1.8 n newest update on to meet euro 5 emmision in newer civic. As i say, u can bring old b16 @ b18 to track, but not on the road even in stock mode.

I hope u understand the diff between oe tuners and 3rd party tuners whereby so many rules n regulations they need to adhere, not only for engine, but for safety aspects also need to meet. But 3rd party, dont need that. Anything coming out from manufacturer plants, must follow the rules. Unless u r buying car from proton, then go to r3 garage, jsut prepare the money, ask them to mode to stage 3. But even do it under r3, since its consider being moded outside coz u r buying standard car, but just mod it under r3 workshop, standard warranty is void, n thats when r3 no need to follow any rules n regulation to mode the car.

By the way, r3 not only dyno tuning the engine using dyno machine only, they also dyno it on the roads and tracks n done reliability test in engine chamber and durability test on the roads and tracks.

People may say its pricey to mode with r3 @ buying r3 cars, but if u taken into account the amount n money they spend on engineering n rnd n hnt, its worth the price. Compare to those that just slap in some mode components, link with laptop, using piggy back or new ecu, tune on dyno, one day job, finish tuning. For r3, some may take a year, some more than that.

N many of them are engineers, not only technician.

i know how u feel, n i feel sorry if that happened. Its a norm when new updated product come out, some may get new update. Its a norm in any auto industry.

If all still the same, this preve sport will have some cues from neo, especially on the rear view.
