[QUOTE="pciericagp, post: 481446, member: 8323"] Dear All, I'm driving Proton Wira A/B 1.6XLi, My car a bit rojak type. Below are some information about it: Engine: Originally: 4G92P SOHC 16v Currently: 4G92P DOHC 16v (Convert from SOHC to DOHC, taken from 4G91 Carb) Gearbox: Originally: Proton 1.6XLi Auto w/Overdrive + Proton TCU Currently: Mitsubishi 4G91 Auto w/Overdrive + 4G91 Auto TCU The car engine tappet sound like shit, very noisy than my previous single cam. I already use Castrol Magnetec and seem more worst. My mechanic said should use 15W or 20W engine oil and 1 stp engine treatment to make it better. Somemore my fuel consumption never hit the best. Very high consuming. :( Now, RM 50.00 only can hit up to 330km max. Anyone that had remap the ecu or tcu that can optimize the fuel consumption? The gearbox always rev. till 2.5K rpm and reach close to 20km/h than only shift to 2nd gear. But from 2nd gear to 3rd gear; shifting time took shorter than 1st to 2nd. And 3rd to Overdrive, shift at 75km/h. I felt little power come sudden at 60km/h. It is normal. At 110KM/H, rpm is less than 3K. Only 120KM/H reach 3K rpm. Anyone can recommend the solution, I drive normally, didn't tekan kuat my pedal. My throttle body kong last week, same thing as your, the ISC tak ada fungsi. Just replace with Mitsubishi V6 throttle body w/ISC. :rolleyes: Good feel but consumption still the same. [/QUOTE]
