i knew this guy...he's from Kelantan.
i've already talk to him and he a very nice guy, not "kedekut " with his knowledge...he told me that his car is all in standard condition. before he play with gen2 cps, he already play with wira gsr.
imagine...that u changed the head manifold with 4-2-1 and free flow exhaust system...
nyum-nyum...u got more power than that...imagine... :)
 
hi guys,just got my gen2 cps around april this year. As far that i can remember, there is no major problem with my gen2. Minor prob like "ketak ketak ketak" sound when i open my window..the engine is so smooth n grumbles deeper compared to normal campro.My dad drives a satria neo with normal campro so i can feel the difference of both engine.

From what i've experience, the old campro fitted to neo comes with longer ratio gearbox especially for 3rd gear.Comparing the 3rd gear of neo n gen2 cps u can immediately notice it.neo 3rd gear would take some time to speed up maybe due to the fact that the ratio is longer. gen2 3rd gear is just nice,after shifting from 2nd gear to 3rd gear, the rpm will increase without hassle. For neo,shifting from 2nd to 3rd would need some time for the rpm to increase but if u shift into 3rd gear at high rpm point,there is not much problems.huhu.Donno if u guys can understand what im trying to say or not....huhu.I can drive through road bumps using 3rd gear with gen2 cps but with neo 2nd gear might also stall the engine sometimes.

In terms of engine, gen2 cps really nice la.No jokes at all...Tried with a normal campro gen2,smoked him like 4 cars.Tried with a vios,smoked him too but since it is an auto, his car has faster pick up compared to my slow response shifting.huhu.But when i got into 3rd n 4th gear,no problem at all.

Once the engine rev up more than 4000rpm, i notice that the engine becomes lighter compared to below 4000 rpm. Meaning when 0-4000rpm, the engine is heavy but after 4000rpm it becomes light n a bit power can be squeezed out of it. I enjoy keeping my engine revving more than 4000rpm for extra pick up but minyak also extra used too. Same goes to my dad's neo, revving it more than 4000rpm the engine becomes lighter.

Comparing the cps with normal campro, the campro lagging still exist.With neo, the lag is really really noticeable.when u want to shift up, u pushed the clutch without step on the gas, the rpm suddenly goes up like 500rpm.Sorry to say, with cps engine, the lag still exist but not as high as 500rpm but maybe 100rpm(rough estimation)..maybe becoz they dont use normal mechanical linkage for the gas pedal so this prob exist.But i dont know, this is what i can think off.Some ppl might know the reason for the campro lag.

In terms of handling, cps is good but cant be compared to neo la. Cornering with neo : 140kmj, same corner but with gen2 cps : 120kmj. I hope u guys understand. But gen2 is more comfort than neo,interior also nicer than neo or pesona.

There is not much problem to speed up from 0 to 160 with cps. From 160 to 195 might take some times. Max speed i drove using my cps 195kmj. The steering wheel doesnt shake at all during those acceleration n max speed but when i step on the brakes hard at high speed, the steering do shake a bit but not that hard la. During 195kmj speeding, i do notice that the sound of the engine is so loud.huhuhu. There is a small gush of wind coming into the car from the firewall.how do i know it came through the firewall?i always felt the wind around my leg area.huhu.Maybe got hole at the firewall i guess.

I think dats all that i can tell now, but if u guys want to ask something, no prob.I would try my best to answer it. What i said is based on what i experience so some ppl might experience itdifferently. I dont mind hearing other ppls opinion. We can discuss n create better solution to avoid problems with our cps.
 
cool...good theory, good explanation and a good experianced...:)
like the video showed, it's easy to reach 180kmh in to 34 second... :p
 
yup...mr djan told us to rev the engine up to 4.5 - 6.5 for shifting gear, if we do this sure can feel the power...the 4th gear of this cps superb..... but hate the 1st sound of the exhaust in the morning seems to hear there were bocor? wonder if u guys experienced that too
 
about the sound during morning time, my cps doesnt sound like bocor.maybe ur piping got loose gaps that causes those sound.cps engine grumbles deeper than campro engine.My dad even notice the different engine sound, sounded like a strong engine he said...huhu..

bro, try to check ur silencer box.
1st time i get my car got that sound too...then i discover that the silencer box "bocor" at the bottom...
 
huhu.. i'm not play wira gsr lah... wira ebo lah... already sell that car..

now buy wira ebo again... as a weekend car.. cannot tahan lah..

yaa.. my car also got sound about 20sec if start on cold engine... i tot if come from LCP.. not checkit yet.. will try put silicon spray on my belting, if not gone.. maybe other prob...

sorry la dato'...im very2 terlupa...do u know me or not? :p
 
guys...need help a bit.cps means cam profile switching so if we use adjustable campulley and we change the cam degrees,does the cps effect still work?Since cps engages at certain rpm so changing the degree might do what to the cps engagement?make it early?a bit late?

Since we can retard and advance the cam and causes the power band to come earlier or later at high rpm, does the cps engagement rpm still fixed or does it shift also??

saya budak baru belajar...huhu
 
huhu...very gud question...
got to asked the sifus for this question...dato nan83...i think he can answer the question...:)

aiyak... dato' ??? dato tua ka.... huhuhu.... of coz la i know you... huhu

nan, hows ur cps now...no more mods?
since u got car with tebo power...

maxpain also can answer the question laa.... me also budak2 baru blajo...

humm.. change the cam degree will not effect the cps switching... cps switching base on RPM to activate it... once the RPM reach the ecu activation setpoint, ecu will give the signal to hydraulic solenoid to energize it, than the cam switch .. mechanically it not related with campully, the cps switching is using the tappet itself...

fyi, the switching system only at intake cam...

just see vid below to know how cps work...


YouTube - Secret behind the Campro CPS(cam profile switching) engine of the Proton Gen2
 
yaaa... no more mods..

maybe last upgrade 1.3piston & extractor....

i can make a question from ur answer...
why gen2 1.6 change they piston to 1.3?
cps pistons did'nt do a good job ka? :)
 
ooo...ic..ic...
no wonder ppl in club do that...newbie :p
 
any 1 here wiling to share the photo of gen2 pistons..love 2 c d different
 
Piston picture tak ada,

valve cover opened can ah? :biggrin:

Hi Guys,

Nice to read on this thread..
Btw, have any latest modification update?
mind to share ?
 
hi.... does anyone know how to get the RPM signal from campro? From ECU? From dashboard meter? so that i can install the tachometer.

pls help me any sifu..
thanx
