Message: <blockquote data-quote="m1adam" data-source="post: 2180378" data-attributes="member: 23739">ur rite mr potssum only the mmc based ems can use adjustable pulley on the intake coz the mmc ems allows the intake cam degree to be advanced bt seimens system does not allow intake cam 2 be advanced coz the cam angle sensor at the intake cam will actually tell the ecu where is the location of the 1st cylinder either TDC/BDC(Top Dead Centre/Bottom Dead Centre) for example the 4g15 engine usin SVDO system under the cam angle sensor is the camshaft at the end part of the camshaft is a metal groove that feeds back info to the cam angle sensor the position of the 1st cylinder so that the ecu knows how to start the firing and injection time and bla bla bla lotsa stuff.This process takes place when u just start ur car so if the position of that groove is at a wrong position the cam angle sensor cant detect where is the groove located thus does nt know the location of the 1st cylinder ur car will start but u will have lotsa symptoms like misfiring,car die off when idle and unable to rev up pass 4000rpm,so 4 SVDO system u cant utilize this adjustable pulley same goes to Satria R3,R3 guys know that Satria R3 uses SVDO system and that adjustable pulley does not work onto their Satria so to maintain the hype they install it at the exhaust end at least still can sell their product so people with no info bout SVDO system will say waaaah sure power 1 use adjustable pulley at exhaust wats the point make the exhaust go out faster the intake time should be longer not the exhaust time.In other words more fuel more air bigger bang.im very amazed that a satria neo owned by handsome boy is usin an adjustable pulley for his campro where campro uses SVDO system which does not allow cam pulley advanced,handsomeboy try ask ur mech wat degree did he set the intake cam im afraid he adjust ur exhaust cam only the intake he din adjust,and maybe he retard ur exhaust pulley thats why ur car die off while idle u make sure u know whats he doing 2 ur car whether hes doin it rite or wrong try ask him what is the valve timing of campro engine if he does not know that means he's a hoax fomen 2 actually know how much to advanced the intake time and the exhaust time u need 2 1st understand the stock valve timing then u can play around so dont b fooled by people who dont know anytin bout campro</blockquote>
