one thing to clear it off, the engine maned as CAMPRO is because the cam profile they used is different from the normal engine (and i don't mean performance engine over here).

The engine did some very impressive figure on prototype GEN2, which is 165BHP stock and without CPS. but same as the production, the engine do equipped with VIM system. and thisfigure achieved without violating Euro 4 emmission standard.

but due to the cost problem (plotong alwaysliked to cut cost for profit...) the engine used some rather cheaper material and the horsepower is reduced to the figure shown today......

and to fully boost the ability of the campro, you need some very skilled engineer to tune the ECU up. which none exist in any Klang valley service centers.... but there's one at batu pahat.

for my Gen2, i can have my 0 to 100 kph with near to 9 sec. and this is achieved without the need to fully depress the acceletor.

CAMPRO is a good anddecent engine. for mine, the torque is maintained from range of 2000rpm to 5500rpm. I don't think any of the "normal" japanese car seen in malaysian market have the same capability.

This statement is valid for my 2005 DEC Lennox black HL manual GEN2. i do not sure the previous batch, but I have a friend with 1st batch GEN2 mentioned the same thing.

The 165 HP, was that only an experiment by the company?
Pretty impressive.  thumbup.gif

With CPS, expect 170-175?
*
The car still exist. if I'm not mistaken, one in Lotus UK, one in Tg Malim & one in shah alam. built cost is more than RM100k if i'm not mistaken. however, the condition of the car is unknown, rumour says that the car is now used solely on technical training purposes. so i presume that they're dismantled.....

i do not know figures with CPS, but according to enginnering, the gain is 30% with CPS, you do the math.....

You mena torque is maintained from 2000 to 6500 rpm.

it's maintained "in a 80~100% margin" and it's proven on dyno.

and dear all, Campro do have the VIM.

and one more, the campro maned as campro becaouse the cam profile is different from conventional "normal" engine. although there's no CPS in there.

the same campro system is used to build lotus APX. but in 3.2 litre turbocharged. just for your info

My arse. Tell me what's the "normal" cam profile, and what's the difference between it and the campro's profile. Its just a more aggressive profile, which shows because power is pathetic on the lower ranges and acceptable on the higher ranges. While everybody is targeting more torque for the normal drivers, Proton decides to go for high range powers with not many people will ever use. That's the only "genious" in the campro design. As for VIM, that's for variable intake manifold. I beg you to open the engine hood and point out where the mechanism lie. So far I only see one tube from the air intake to the intake manifold. Show me the second, shorter tube please.

And so what if the campro system is in the APX? We'll probably never see that car in malaysia due to its braindead aluminium chassis which Proton does not have the capability to build yet. Building a huge engine is easy. Building an engine that has 100 horses/litre is not. And proton is good at NOT being able to do the second one.
*
so dude, explain to me why i got a near flat power curve on the latest batch of Gen2????

you don't see the mechanical there, you can only get it when you turn a PDT 2000 on. or a overhaul, dude.

Too much bashers and these ppl filtered out all the necessary infos for the new comer. can't you all just answer the question? why da hell must all the bashers add all the unnecessary statement? this is unethical!

Not really. You buy foreign cars which already imposed some hefty amount of taxes to the Government. And the government supported Proton do get benefits from it. But no one in public knows how much help do they received from the Government.
Did you dyno it?  Or just simply said it out just like the Proton brochures shown to us. Scan your dyno page and show to all of us if you dare and prove us dead wrong. Otherwise it is just another baseless assumption.

oh, i do wish to, but currently i got limited access to internet since i'm at my new home and I cannot upload the chart yet. once my internet connection is restored, I'm more than willing to post it up.

so it might be a while for me to get my streamyx....

im not a basher. i can says im a proud supporter of proton but for u to says u get a flat power curve in latest gen2 engine.... is either ur engine is special made from proton or the dyno machine got something wrong.

our current campro engine doesnt come with CPS or VIM. is just a normal 4-valves DOHC engine with aggrasive camshaft. u can email proton n ask about it but if ur engine really can get flat power curve across the RPM.... u better sell back ur engine to proton with much much higher price so they can dissect it back n learn how the hell it can get flat power curve across the RPM without sumthing like CPS, VIM, VVTI, I-VTEC, Vario-Cam, Double vanos.. etc etc.
*
Oh, the flat curve is after a proper tuning somewhere outside the Klang valley, and I do sure I seen something on PDT2000 which resembles the VIM setting. prove me wrong my explain all the content in PDT.

Will post the chart in near future. but not now.

Why should I trade my engine out? I can't keep it myself? Your statement doesn't make any sense to me.

Stop talking bullcrap and give me a dyno chart to proof it. I am basing my argument on the dyno chart released by Proton, so if you wish to call my argument a baseless argument then it is only fair that you provide one with your own definition of a "sound argument". If you fail to do that, then I believe your own words apply to yourself more than it does to me.

And you replied:
I wonder, proper tuning to gain back your flat torque curve. Why isn't that factory tuned? How many average buyers would go for such a tuning or even have the extra cash for that? If you want to talk about tuning, I'd say the VTEC 1.6 engine could ravage its ass with that kind of tuning. Flatter and wider torque band, higher horsepower.

And mind to explain what PDT is?
*
Oh dude, if u don't even know what PDT is, you don't even have any right to comment on the Campro. doh.gif

PDT stands for Proton Diagnostic Tool which is used to check all the error logged in the ECU (and yes, Gen2 logged all the error to the ECU, including the Door Ajar sensor)

Until I have a proper conenction to internet from my house, I can hardly have any access to internet. My access to internet is very restricted and it's impossible for me to upload any attachment currently.

VTEC? oh pal, B16x series engine is designed as a performance engine in mind, while campro S4PH found in GEN2 & WAJA is designed to be a Thermal efficient, cost efficient and Green engine which exceed Euro 4 emmission standard in mind. I won't mind to tell you that Campro series design can be modified to a more powerful engine without deploying any CPS technology.

The near flat torque curve i mentioned is between 2500 to 5500rpm before the torque started to drop below 80% peak. From what I understand from proton, The result is achieved by deploying VIM and electronic throttle body control which work similar way in the Civic 2006.

I'm not bashing City, but after tried most of the cars in similar price range from 50k to 100k (as those car actually same class in terms of engine capacity and type) for nearly 2 weeks, the Gen2 wins for me for superb handing and good power on wider rpm range. the City VTEC maybe better, but the i-DSi cannot even match with the Gen2 on all these. the only thing that City surpass the Gen2 for both i-DSi and VTEC is the smooth gearbox (but again, I liked manual transmission more...) and the great turning raduis. the cabin? for me Gen2 better, as mine is dual tone colored (black & beige) quality is almost the same.

Vios? Aveo? they're all not satisfactory to me. at least the test drive unit they provide is poorly built. and I have had enough with the Toyota Fiasco previously.

FC of course Honda City IDSi win, and ultra seat, build quality, everything is far ahead of Proton. One of my friend patiently save his salary for two years riding a kapchai go and back to work. He manage to put a RM12,000 as d/payment and now he is the proud owner of City IDSi. FC for him to 'balik kg' to Kelantan quite impressive.
*
yeah, FC definately i-DSi win. but.....there's better one from honda..... I've heard honda brought in Civic Hybrid which the FC is almost a kapchai's standard.

if u want good FC, Gen2 is not your choice. as the FC is not impressive enough. at least for me. But City cannot provide you a joy-of-ride like Gen2 icon_rolleyes.gif

R3 does not have the CPS ver. Campro YET. and this statement valid by the time is posted.

but 130bhp Campro with VVT might be installed on SRM. and they're planning a 1.8 Campro Turbo for SRM.

i've sat inside gen2 and inside city 2006 model.
the gen 2 is definitely crap if u wanan compare to city interiors.
city alto look small..but its freaking comfortable. the gen2, well the seats are too hard for my ass...and the dashboard plastic's is a sight that i cant stand.....even the steering feels plasticky.
honestly, city beats teh gen2 in every single position apart from price point
*
it's weird then. you're commenting on normal Ver? and um....i would have to agree that the steering feels fragile..... but the wholedashboard, door trim are well decorated. and it feels better and mode solid that the City. The city, got once i seen the panel moving when the window is winding up........ doh.gif

Mine is HL, using leather seat and so far anyone hoped into my ride on it also commenting the improvement made by proton.

maybe normal very is still bad?>????

i'm back.....as stated before.....I have limited access to internet...however i would not have anymore comment on all the bashers anymore....they just upsetting me....

Okey, for all Gen2 owners that willing to improve the engine performance via tuning (like the one shown in chart, which is somewhat similar to mine..) there's 2 place to go.

1st one is WJS Hijawan which belongs to Proton Edar, the map is shown in the website http://www.protonhijawan.com This one is FOC for tuning as long as you register as G2C member when you're there. but it's located at T.maju, near Batu pahat summit.

another one is Trend Point at pekeliling which ALSO belongs to Proton Edar. this one you need to pay RM150. Go there look for a guy named Ah Loong(except tuesday), he's the only one knows the thing. others will not know. this one need to pay more, but save the hassle to go to Bt. Pahat if you're in Klang valley.


and finally, to help the campro perform better, I recommened FULL COOLANT FLUSH which means u need to pay some RM1xx to pay all 7bottles of coolant, and you cannot add any water to radiator. coz the heat generated after tuning is incredibly hot if u use normal water + coolant solution.

and I also recommend Either Syntium 5000 or Shell Helix Ultra for each 10k service.

AND, I also recommend for a full X1-R treatment (approved and selling in all Proton Edar Service center for every service. by using X-1R, you can buy a 4ltr Engine oil and top up with it. and it's right on the optimal oil level.

if you miss any of this, you won't get the curve like the one you seen on the page before. This rule does apply to all campro engines.
it might come out a bill of a Volvo service, but If you don't do it...your campro engine will not soar. thumbup.gif

This is what Idid on my Gen2. if you all interested, can have a meet up, I got more tuned Gen2 owner which is more willing to share their joy after a proper tuning.

and I just confirmed one more thing about VIM. the VIM function is actually emulated by the electronic throttle valve. that means it's a variable intake control rather than like the Myvi's VIM, like the photo above. the part with gold color..... doh.gif

proton coolant is premix coolant not 100% concentrate.

save your $$$$ go to spare part shop buy 100% concentrate coolant and mix it with water. It's the same. WHy pay more ?
*
they're not premix. i've seen the coolant substance in Hijawan as I mentioned before. they have a tools to measure how mucu water is contained in the coolant. and the result from the proton coolant is "No readings".

So, your statement is not true at all. dude.

Reading your posting, it seems that your engine is tuned to run leaner than usual, since the engine heat increases after that so-called tuning. Is that what you're referring to?
*
it doas not run leaner. although it's leaner from stoich burning. in fact the fuel is tuned to be richer from the original settings. they have a formula to tune which must be adhere to. not many ppl knows the formula. So, most of the forman don't know it.

I've mentioned at my previous post for where and who to look at for Campro tuning.

So the engine generate more heat and need careful cooling. Btw, how much is the total cost for all the changes, tuning and flushing?
You mean this only for the Hi-Line version? I mean, is the Campro engine differs with the Hi-Line and standard version?

No, all campro engine include Waja are the same
