[QUOTE="KRZ8v, post: 4458959, member: 80206"] Hi all ZTH members, Recently I decided to wash my car and the engine bay b4 Raya. As I wuz wrapping all the water sensitive component @ the engine bay b4 washing, I notice my cam sensor position is turned fully clockwise (Advance if I m not mistaken rite???) So after the wash I decided to re-position the cam sensor back 50-50. But the problem appears as I turn it 2wards anti-clockwise (Retard???) Advance: ~Good throttle response ~Powerful pickup ~Turbo lag kaw2. 3.5k rpm spools, 5k rpm 0.5, 6k rpm above peak. Retard: ~Very bad throttle response and I mean VERY BAD no kidding ~No pickup hard to reach 4k rpm ~Turbo spools super fast. 2-3k rpm spooling, 4k rpm 0.5++, 5k rpm 1.3 wastegate screaming but boost still climbing:confused:. ~Engine overheat fast. ~Bad FC:bawling: The problem is if I set back the sensor to its original position (b4 I "usik2") which is fully Advance, my car will have instant response and better idling. But I muz pull my rev higher juz to feel the boosting force and "kepish" sound. If I upshift @ 3-4k rpm, it feels like u r driving a normal aspirated car. I tested my fren's Perdana Evo3.... Instant power when u floor it. Boost kicks in as u floor the throttle. How to adjust the sensor so I can have better response and faster spooling??? Proton Saga 4G61T Stock stended. Except for the turbo TD05H VR4compressor +Evo3turbine(which makes it lag even worst btw) Thanks y'all and Selamat Hari Raya..... Drive Safe....:driver: [/QUOTE]
