Changed the following:

- Spark Plug's.
- Air Filter.
- Engine Oil.
- Engine Oil Filter.
- Cleaned the Throttle Body.

After all of that, it is still giving me 48 Kms per block.

Hi all! First look at the problems. When i first get my Yaris it was very econimical for about first 20 000Km "stock". Then i started to put some HP Enhencer; Cold air, Injectors, Performance muffler,Changes the KS emplacement. With that in mind the ECU recalculate all the fuel maps and then put them in "Cell" Driver's habits. It almost sure that the car MPG will drop significanly. The best thing you can do is that you clean everything MAF heating resistor the IAT Throttle plate and do an ECU reset. Drive it very normally and it should be better in your mileage rates. ;) It works for me....

hi.

500 kms per full tank is a bit unrealistic, especially in a hot country, and probably questionable quality of fuel.
plus the 1000 cc engine's probably underpowered, so you end up not getting enough power, and the engine's overworked (and may consume more petrol to get the engine revving and starting).

change your driving style, and try to keep the revs below 2,500 rpm. i get 450 km per tank, est 17km/l in real world driving conditions out of my 1300 m/t yaris sedan.

you mentioned that there are a lot of uphill roads in your country, inclined roads make the engine work harder and consume less more petrol.

also try to take out the unnecessary junk inside the vehicle. leave just the spare tire in the boot, if necessary.

try to drive sensibly. sometimes the best modification is done behind the wheel.
