anyone interested in fuel addictive ?

Wondering why even when I press full throttle , the Preve just won't rev or hold the gear higher than 4000rpm? It's like, stuck at 4000rpm or something. Annoying. Feels like maximum power isn't being utilized.

CVT gearbox characteristic. read more on how CVT works.

switch to full manual mode if you're using CFE (slide the gear lever to the left), then you'll see it rev to 5k++.

how addictive is it? or you meant additive?

yes.. and dont use paddle shifter for shifting, let the cvt change the gear for u automatically..

You mean ... if slide gear knob to left and CVT still change gear for us automatically? I thought that position for semi-auto ... we still need to change gear like manual gear.

Yes... it used to protect your gearbox and engine...
what the reasons what you to maintain at 5000-6000rpm on the same speed?

the CVT allowed to rev till 5500-6000rpm before shifting considered very good enough...
unless u intentionally want to blow the engine at 8000rpm then nothing we can help...

we dont talk about the CVT issues here... NONE of modern car allowed you to rev till red line as most of ECU with rev-cut features even though you driving manual car... i guess my responds clarified your doubts...

reverse camera should not void warranty as the owner guide book mentioned that the HU are ready with reverse camera and advise with professional with such installation...

i guess only the reverse camera can improve your reverse parking skill...

yaya additive
check out my signature below ya ^^

OK ... thanks. I should try this.

So means there is nothing wrong with the CVT holding the revs at 4000rpm ? Is 4000rpm the best max power/torque output already? I still finding it hard to believe.. Cause throughout all gears it holds at around 4000rpm only. I thought different gear ratios should be different shifting point?

by using S, it should able to hold at 4000rpm... but more than 5000rpm+++, it will up shift...
so no point to rev more than 5000rpm as it is not the BEST max power/torque, so why wasting the fuel for poorer performance?

Look at the torque graph below (the blue line), max torque begins at 2k RPM and drops after 4k RPM. There is no point revving past 4K RPM unless you are gunning for top speed.



The Preve's CVT is torque based, means it shifts according to torque demand as required by the terrain and the user's throttle input. If you need anything less than 205Nm, you can get it before 2K RPM.

This in fact showcases the benefit of the turbocharger+CVT combo, you can stay within max torque no matter your speed, something not as easily achievable using conventional stepped transmission.

Ahh... So it peaks around 4-5k ? Ok k .. No i didn't mean i want to rev high or redline.. I just wondered if 4k rpm was the best shift point. Cause noticed the CVT held it around there whenever full throttle. Thanks for clarifying

It peaks around 2k and stays relatively constant until 4k RPM (read the blue line) after which it starts to drop

so once you reach 2k you already get maximum torque, no need rev to the moon to overtake trucks....the joy of turbo

Hi there~~i went to Sg Besi Proton Edar Branch today~
It is noted that they are also able to give me the Proton Preve Premium "dealer" discount of RM6000, and also offer me the R3 Body kit (he said RM1k++) and the R3 Rim for another 1k++ (promise to be ori, but had to check price)~~

Anyone here know better SA to recommend?

I read through the threads here...some even mention they are able to get the price at sub 65K~~

Many thanks for replies in advance~~

If you press the pedal to the floor, with the updated ECU/TCU settings, the engine will rev to 5500 - 6000 rpm. You will find that you have trouble going past 180 kph.

Relax your pedal pressure and allow the engine to rev ~4500 rpm and you will find that the car speed picks up considerably. You can get 200 kph quite easily. The trick is *relaxing* pedal pressure to go faster. Counter intuitive but it works.

In the original ECU/TCU mapping where the engine will not go past 4000 rpm easily, the trick was to use S mode to accelerate to 180 kph and change to D mode to accelerate to 200 kph. Now you just control pedal pressure.

aiya no funs liao

relex pedal... hmm will try this after change tyre...
currently car vibrate at 115kmh++

I enquired directly to Kristof of Punch Powertrain about the improvements on the VT3. My questions were forwarded to his colleague Fikeri Yusof. the following is the email exchange.

Although the VT3+ is currently implemented on the Suprima and Preve LE only, future Preve models will adopt it as well. Something for future Preve owners to look forward to.


There was a couple of intermediate email exchange but due to irrelevance I will omit them here. The next relevant email is below





So as you guys can see the improvements is not only software, but also the mechanical parts. Kudos to the team for answering my questions so thoroughly when other carmakers will probably shrug me off.

Goes to show Proton is not ready to rest on it's achievement with the CFE+CVT powertrain design.
