Btw .. this happened to me today 
Engine overheat problem
Radiator sumbat > Overheat. Finally found the cause of temp rise.
Instead, clean the radiator and crimping the top cover back => Rm85
Was given the choice of new radiator Rm250 (but from China) and Recond radiator Rm230...
With these option, I might as well clean and use back my own. At least I know it's original.
Now my engine is good as new ...   well almost.

Another happy news; at the drop of first bar from fuel gauge produce 156km... happy to know I can hit my usual fc of 450 - 500km for full tank.

Throttle Controller??? 
Wira is using mechanical throttle with cable. Not the new electronic throttle. What kind of throttle controller do you mean? Mind to enlighten us? 

For auto, you can get 430km is pretty good.

Anyway, change my PCV valve. During idling, my car maintain at 1000rpm. So that one good sign.
Next to factors I'm hoping for ... FC consumption improve and no makan minyak in engine. 

Damn that fuel consumption is so good!! Got any mod?
Mine 30 litre 350km only  stock from factory
Thats good news! Good for you
