errr...IAFM is external device at the air intake rite?so,is there any chance to put it to normal campro arr??

I prefer changing the hi-cam to a higher one. Can save petrol if kept revving under 4k rpm.

I think its possible.

it tot original cam campro oledi use high cam.or i'm wrong???dat's why campro power only comes at high revs.

CPS has 2 set of cam, once hit 3.8rpm, it will change to high-cam.

u can't compare with an old generation engine. new engine has stricter rules on emissions etc etc.

try compare the CPS 1.6 with Toyota Altis VVT-i 1.6 or Suzuki Swift Sport VVT 1.6. that's the closest that i can compare.

CPS is leading in that comparison theoretically.

change to highcam can save petrol??..

2 sets of cam??... or u mean the cams has 2 profile lobes like vtec??...

somehow i dont see any difference in performance during switch over of the cam profile....

Campro is the engine family. They're phasing out the normal Campro and are now offering it in two flavours.

1) Campro IAFM - think Honda i-DSI
2) Campro CPS - think Honda VTEC

The 2nd cam in CPS is not as 'wild' as VTEC and it also engage early (3.8k) compared to VTEC.

seriously, this is the first time I heard such thing as installing high cam can save petrol.

so, they basically have the secondary cam eh? How's the activation of the higher cam? Is it similar of to the VTEC's?

I thought CPS is something like DVVT, VVTI, etc?

can install CPS or IAFM to older CamPro engine? How much the cost?

CPS got two profile cam (low lift and high lift)... As long as keep revving before the activation point, it still use low lift, thus normal FC.

B16A is useless below 5000rpm even with B20B block but after that .....
For drivability and fuel economy I think CPS is better.

And if so the CPS is better, how come the redline is still at 6500RPM (same as 2002 Waja). I thought it can rev higher?

The actual red line is 7200 rpm (rev cut). Try for yourself la....

CPS = cannot perform smoothly

It's quite smooth actually... have u actually driven one before?

As mentioned earlier, in THEORY, it can outperform VVT-i and those. Anyone tested yet?

noler

IAFM is about variable length intake manifold... something like VIM, but controlled mechanically.... totally different with i-dsi.... i-dsi utilises 2 sparkplug at each cylinder.... they fires in sequence for good fuel saving or fires together for better power.... it is controlled by car onboard ecu....

then whats the use of cps leh??... jz to cover the torque dip in the dyno chart??..

nope... think CPS as something like vtec.... they have similar number of camshaft with any other engine.... but normal engines have 1 cam lobe per valve.... but cps/vtec has 2 different cam lobes on 1 valve... when cps/vtec activates, a solenoid activates and slides a rod to connect both cam profile rocker arm together and thus, the valves play according to the higher cam lobe/profile...

understand??..

can.... get complete set cylinder head and intake manifold with wiring and ecu all together and fit into ur existing campro...


ehh wait... does normal campro has the same cylinder block as the new campro cps??...

should be as proton is fitting it in all cars in stages

already tested the new saga / gen2 and waja cps. helping my friend to decide either on gen2 or waja.
compare with the campro without cps, the one with cps has better and smoother ride.
and most of all, better low end torque distribution.
no more auto revs / jerking
