dats the million dollar question sir, how indeed.. the thing is, i can introduce an external valve to tune the idle speed, but i think its unorthodox, lol.how to alter campro idle speed?
iam no sifu sir, just an ordinary joe je.. back to the question, it depends on the dynamic stability of the engine, the placement of the engine mounts, power lap between the cylinders, etc. no two engines are the same, even if they use the same code. in ur case, u can go visit any proton service and ask them to increase ur idle revv, shud be easy for them. i highly suggest going to subang proton service center, behind the metro bus depot, near summit usj. they dont have too many cars there fyi, a good place nonethelessSifu xtremeleo, speaking of idle speed, I'd like to ask: why do some cars rattle and loosen things in the car like the dashboard when their engine idle rpm drops slightly lower (say, less than 700/800) whereas other cars (in my experience, Proton Perdana V6 and Nissan Sentra B14, both stock) can let their idle rpm drop to 500 or even less but still do not rattle?
i am actually tired of sending it to proton service center already ==" everytime i get useless feedback from them... wasting my time driving to the center...brand new BLM idling @ 600rpm? thats already a problem...in the ecu its set to 900rpm. I'd say its time to let your mechanic check this out...
Not rattle resistant. Actually every engines differs in their stability at low speed based on balancing, fittings, and construction materials. V6s are generally well balanced and smooth, hence being extra stable even at low speed.Thank you for explanation, xtremeleo Actually the Perdana and the Sentra are not the problem, these 2 cars don't rattle (the Perdana especially) even if their rpms drop to pretty low levels. My other two cars at home, a 1985 Toyota Corona with a 20v BT and a 1989 Honda Accord CA5 start to rattle when their engine rpms drop to less than 800. The Corona was like that even with the stock 4A carburetor engine. That made me wonder about the seemingly significant difference. At first I thought that it was due to engine age, ie. newer engine models are designed to be more rattle resistant, but the 20v BT is the same age as the GA16DE if not newer, no? The Perdana car design and engine is not new either. Got me thinking.. :hmmmm: But thank you for your explanation anyway..
