Hi guys,
I am new here and decided to join the forum after observing it for some time and finding the members here pretty civilised and well mannered unlike some other forums!
Anyway I got my Waja CPS about 2 weeks ago [ Blue Agate, MT ] and I have just gone for my first service yesterday. To be honest, I am a bit disappointed with the power of the CPS engine. Maybe my expectation was too high or maybe the engine still hasn't fully run in yet but I find the performance lacking in the lower rpm range.
Welcome
Its common sense that mechanical throttle system will give you better faster response than drive-by-wire. I'm also using LMST 1.3 before (open pod, full exhaust) and the lower RPM is better. This maybe because its using a simpler carb system than a complex injection system resulting faster response and the gearbox ratio is shorter (2nd gear max at 85km/h when redline while CPS 2nd gear max out at 100km/h redline). Oh yeah, I think the main factor is LMST (in your case Iswara) is much lighter too.

From my experience with 2 previous Iswaras [ my first car was a 1.3 manual ] this is the best way to break in engines. Some of you may disagree, but to each his own, I guess! My first Iswara 1.3 had a complete exhaust upgrade plus a K&N filter [ sorry, I am a big K&N fan! ] and I could still outdrag a lot of Wajas and Wiras even after more than 300K mileage.
Anyway back to the CPS, as mentioned by some of the members here, I could feel a slight buzzing and vibration from the engine at the 2600-3000rpm range especially in 5th gear. I told the service centre about this and when I went to collect the vehicle, they have replied "normal for CPS engine" on the receipt!
There was also the 'nyuk' sound from the front wheel when turning over uneven road surface mentioned by others and after the service the sound is still there!
About the dragging matter, the most important thing is power to weight ratio of vehicles and gearbox ratio. Notice how car usually been out drag by those kapchai at traffic light
About the service/warranty claim, assuming you get your car from EON not Proton-Edar, I-Care service its not applicable. Otherwise just called I-Care and tell them whats your problem. Its a kinda centralized system where they will make the appointment for you and will call you up after the service is done.

I would be installing a K&N filter after this. Thereafter I am looking to get a complete R3 exhaust system plus the AFC meter and perhaps even the iridium spark plugs. This package should be able to release an additional 20-30 horses. Hopefully then the poor torque response at low rpm could be solved.
I would appreciate if any of you guys could give some tips on improving the engine performance besides what I have mentioned. Thanks and cheers!!!
I'm also upgrading to K&N. About the exhaust, I think better wait a while till R3 comes out with exhaust system specifically for CPS engine (the current one is for campro). About the AFC, better wait first because you will be voiding the warranty and don't know how much HP can be gain. But, I really doubt can get 20HP (15%) with these mod.
Just my 2cent.
