I have recently purchased Vitz-2011 new shape, after that Full the fuel tank.It shows 9.5 KM/L and over all 585 KM of tank capacity that can be run.
This 9.5 KM/L increased slowly up to 11.2KM/L after 300 KM used. I was vvvv upset and checked the vehicle from enercon wks center G-10 (near Islamabad H.Court) he has checked and said its 100% OK, but not satisfied and after used of 140KM petrol used about 12 liter so consumption come 11.66 KM/l.
again i go to another wks near Daewoo Naseerabad, Ali automobile, he checked with carman scanner. and told that all sensors are OK, no fault. but the problem was SAME.
after that i have friend that has same car, he told me about RE-Set of computer (ECU) that is done by as.
1) Remove the Negative terminal of Battery for 5-minute.
2) again Tight the -ve terminal.
3) switch ON the car.
4) The ECU reset and for 20 second the engine was unstable, but after that become STABLE.
5) Drive the car for 30-minute on normal road as well as Motorway, for observing pakistani road conditions as well as Pak peterol vs engine conditions.
6) The dasboard computer that does not go beyond 11.2, goes up to 19KM/L and that is confirmed.
7) Now the car is so light and changing Gear (AT) quickly.
Now it shows 702 KM instead of 345KM, and duly verified.
I am so happy and telling it to all friends the reality.....that is safe .
Dont open/clean the Throttle Body..................untill the scanner shows 0-fault.
Be aware of it.
