campro is under seng (small engine)project which is undertaken by lotus, and it took 2 years to develop it which comprises 2 variant 1.3 n 1.6 using same engine design for 2 displacements to save cost,and it already cost them nearly 2 billions. It is in lotus proactive magazine,but need to search an old one.

It is develop to accept cps n vim tech,but dunno why tm introduce it too early before cps n vim been coorporate into it, but old story,nothing much can do.

While cfe is under pheonix project which started on 2008,which supposed to develop cfe together with new trans(during that time, beside manual,they opt for 5at,6at, twin clutch n cvt,and at last,they choose cvt due to cost versus performance), and the idea of iafm+ originally came from the engineer that involve with developing cfe. They mentioned that why not create an n/a variant from cfe,which they believe they can do that within the same budget.

And there are family y engine program for future engine, but since it too costly n need colloboration to reduce development cost, it is still pending,but initial work has been done. Since prtn has new owner,dunno whether thid project will continue or not. Initially plan to produce 1.2,1.5 n 1.8 gdi engine with twin pulse turbo.

Since colloboration with mmc still not finalised,n prtn has new owner,so hopefully,if everything run according to plan.maybe in 2014@2015 we can se this project being fruitful,but for the moment,it is just only a plan.

Everything need money,hopefully new owner can provide that if they want prtn to improve.

Hybrid project is already run, but many things need to workout before release to masses. They are really careful nowadays coz dont want trouble in the future.

Even p321a,it was table at the same time during development of exora. The initial stage of design n engeneering already slowly done during that time. And the original design send out to italdesign coz dsz want prtn to be a serious car maker,even many idea from pwrtrain comes from dr wolfgang(ex bmw man) himself,and p321a is also under him. Thats why getrag n punch been selected as trans supplier coz they did suply trans to bmw before. Many that involve in this project also have done work with bmw before.

Sorry, too much off topic.

mat79, love your bits and pieces of valuable information

Awesome post as usual mat79, particularly interesting is the genesis of the iafm

actually what is the improvement from IAFM to IAFM+ ?
tried google around, just found that it added cam profile for cvt, cant find torque curve and other detail...
any change on the spec and any improvement fuel efficiency?
n/a variant from cfe is IAFM+? currently used in Saga FLX?

do read more posts from mat79 in persona r thread. iafm+ not found in any proton cars yet.

iafm+ solves the low end torque problem where max torque arrives earlier at low rpm than predeccesors.

then my car (FLX) using wad?

IAFM- ?

Campro iafm+ refers to the entire engine, not just the iafm. As far as i know the difference between the campro iafm+ and campro iafm is the cam profile, NOT the iafm. Campro Iafm+ was introduced with the saga flx.

Essentially, the campro iafm+ was designed to achieve its max bhp and torque at a lower rpm, to keep the cvt running within its specified operating speed. Hence, it also results in lower fc because you dont have to rev as high as you would in the older iafm engine.

I just got my Bold last Friday. Excellent ride, and the whole family loves it. But I've noticed 3 bothersome things :
1. the steering badly rattles when I hit 100km/h. Wheel balancing? Will need to check this out but since everybody's on CNY break will need to wait till end of the week. Can SC cover this or better just go tyre shop?
2. engine is loud (from the outside)! But luckily it doesn't sound that bad from within the cabin.
3. the (radiator?) fan keeps on operating (again, very2 loudly!) even after I turn off the engine. Only goes off when I arm the alarm (lock car doors). Normal izzit?

Any other Bold users with similar or worst experience?

Any good recommendations for car tinting?

Off topic : I've swapped the default Clarion unit for a DVD/Touchscreen unit, any takers for my old set?

PLUS hway near taiping towards to north...

I can tell you the 3rd is normal. My Waja CPS also like that. according to service center, they say is to cool down the engine. not sure how true it is but 4 Years di my Waja still running good

two radiator fans of coz it is loud lo. haha.

But then, it is normal for the loudness. At least when you're in the cabin, the sound isn't that noticeable, unlike that empty coke can saga.

1# Quite a few new owners commented that the steering vibrates over 100km/h. Hopefully this is case by case, a bit worried for those soon to be owner

The ECO Tint provided is not dark enough Definitely have to change

Hmmm, cool down engine when the engine's already turned off? Weird design

Added on January 23, 2012, 2:07 amIt is loud! My daughter ran away when she heard it.

Added on January 23, 2012, 2:09 amDid CPS Exora owners experience this too? Any ideas?

for no 1, i think it is due to wheel balancing. If it is wheel balancing,just kauw tim with ur sales person, ask him or her to pay it for u if u r doing it outside coz not all sc offered balancing n allignment service,just remember,its normal for tyre shop ask u to do allignment also, do allignment is ok, but just ignore if they ask u to change chamber nut. Ask them to adjust right n left toe to zero,and if they r lazy(they will answer cannot, road surface is not flat, need to adjust negative n yadayada), ask them to adjust total toe zero. And just ask sales person to pay it all.

If it is due to tyre problem, go to sc to ask for replacement.

No 2, it is normal,but actually slower compare to previous cps coz the hood already has sound insulator. Just check whether yours come with it or not,coz only bold cfe has it, so i presume urs is bold cfe.

No 3,its normal for campro based engine. It is cooling period,depend on situation. Just remember to use 100% original coolant for campro based engine,dont mix with water@use ordinary coolant. And it only need to flush every 30@40k(check service manual), n remember to send it to branch sc coz flushing n refilling new coolant is really tedious,n really important that they are doing it properly coz it will lead to big problem,such engine overheating n ruin ur internal engine parts.
Periodically checking the coolant level so that will notice whether any leakage happen coz normally coolant level wont reduce in short period,if reduce,just a little bit before u flush it at 40k.

And bold premium already come with tinting, why u want to tint?if still want to change tint, remember to peel off the old one coz if double tinting @ side windows can cause u lost ur 10 years power windows warranty. However,vkool,aircool, ecotint n etc are good tint, depend on ur budget,still many good tinting out there,depend on ur budget.

Hopefully u just change the head unit without tampering any wire inside coz tampering can cause u loosing the warranty on some electronic parts. Better check urs owner manual.

Iafm+ already used in flx n flx se. They are many changes,already mentioned before, iafm+ engine derived from cfe engine with all improvement same as cfe without those related to vvt n turbo unit,iafm unit still the same,just improvement on material used n the flap/butterfly, and iafm+ using 32bit easyu torque based ecu regardless manual@cvt,compare to old one(except persona elegance)16bit ems700 load based ecu,n with 100% new perimeters n calibrations.

And if u want to get better fc in town,dont drive more than 2k rpm(during turbine unit statrt operation), n dont worry about pickup(torque) coz due vvt n other improvements, at 1.5k rpm,cfe torque is already exceed maximum torque of cps@4.5k rpm n i know its hard to cntrl them due to turbo feeling,but u can actually coz u already can speed up to 80kmh++ below 2k rpm.

These are being told by the engineers.

Added on January 23, 2012, 2:35 amactually running radiator fan is not really weird, some conti engines have the same function :-). Savvy renault based engine also has the same function.

Have to agree that with loudness, but wait untill you hear prince engine compressor n radiator fan sound in pug 308 :-), i think u will run away,not ur daughter. But its good to have silent engine. For me,toyota is the best in term of slow engine sound.

N agree also bout saga sound dampening,wish could be better inside.

Added on January 23, 2012, 2:50 amahh,forgot to mentioned, dont engage sat mode if want to get better fc coz run in full cvt mode is better than engaging sat. N always check ur secondary blower controller,just used it when needed, normally if fully occupied, coz can save a little bit fc. I think front ac vent is just enough even for 2nd row unless during really hot weather. And dont forget the temperature control is diff, to the left is more cooling(full blue doted), to the right is less cooling(empty white circle)(if they dont change the control unit from previous one)

wow! thx mat79 for the really detailed and useful info

never knew that double tinting would void the power window warranty. Wished that Proton would come factory with darker tints next time

---

Added on January 23, 2012, 7:03 amI've got full praises for the torque. And yep, like you mentioned its hard to control the speed only because it reaches 100kmh too easily and effortlessly!

mat79, since you seems to have connection with people inside proton, can you request them to put sunroof for the next exora bold fl? quite few people have requested sunroof for exora, from what I read at the comments in paultan. I'm thinking of buying exora somewhere mid next year, and really hope by that time exora bold fl with sunroof will come out

as an owner's POV, SAT is rubbish.

what's SAT?

a button to engage the advertised 6 speed mode.

the 3rd part, i advise you to check IF there is any coolant at all.

my BLM came back from accident, radiator fan wont stop blowing after i drove it..i thought it was normal, as my friend's campro persona exhibit the same symptoms.. but even after 10 minutes, it was still whirring away..

later i found out, the workshop forgot to fill in ANY coolant at all
