Hi guys.

Mind if I join you guys. Owner of 1.6 wira but had a serious headache on the FC after changed convert it to 1.8.

Well, long story short. Couldn't recall how many litre but a RM70 bucks won't pass through the 220km mark. Improved to 260km on highway cruising at 110kph but that still high rite

Had it tuned at proton chan sow lin hq center, lim tayar either manually or thru machine, improved a little but still consider high. Usage is like 70% city and 30% highway.

Some suggested this got something to do with the transmission. So I had it changed, half cut from japan I believe and it is an auto BTW. Managed to touched once at 300km per RM70 petrol and now all it remains is history.

Then all thing back to square or worst is I had it top overhaul........blow gasket while travelling 160kph from K.L to Melaka. Repaired, fixed and installed it back to where it used to be and now all I could get is 200km per rm70 bucks.

Now my only suspected problem is its ECU. I'm on 1.8 but used back the 1.6. Does this cause all this high FC?

I'm not a speeder but I'm really desperate and really in hurry that night. I know nothing justified and give me right to speed.

BTW I'm not saying I always top 160 everytime I hit the runway. Its that only one time and it burst my engine.

You fren reach destination after 160 and manage to get 300km mileage but I straight masuk workshop. Something is not right with my car.

My high FC is all due to 70% city and 30% highway Kesas to be exact, how to top 160 leh.

I'm in 1.8 now with 1.6 ECU all because the mechanic mention it can be used. I really screw it up.
