Sorry guys for the late reply. First, my uncles fren sold his tuner thingy and dun ever go to proton edar to tune.
Secondly, all Waja petrol tank is 60 liters (read the waja specs). When u refill of coz u dun reach 60 liters coz u cant finish ur petrol n go pump rite? Heres the formular I use to count for 60 liters how much my car can go.
60 liter petrol = RM1.92 x 60 = RM115.2 (Really from no petrol to full)
1 tank distance = 630km (my current car usage)
$ per km = 115.2 / 630 = RM0.18++ (0.17 when my tuning is better last time)
Now i'll teach u how to get ur cars 60liter km usage. Example u pump ur petrol when the lamp is on n u hav travel lets say 500km n pump 50 liters of petrol
50 liters = 500km
60 liters = w km
so 500 x 60 = 50 x w (remember ur form 4/5 maths?)
end is w = 500 x 60 / 50 = 600km (for 60 liter petrol)
Lastly, yes i can go 600+ in city driving (used to), since my tuning alr out abit i pump my petrol when i hit 570km or so. The waja low petrol lamp hits when u hav around 100-150km worth of petrol left. How to know how much petrol? Easy, 60 liters minus the petrol u pump in till full tank n u know how to count how many more kms u can run b4 reaching 0 liter.
PS Stepping hard means hitting high RPM not high speed, at 3k rpm its around 110kmph alr, do not hit more than 3k rpm b4 u reach 110kmph coz it'll increase ur petrol consumption.
I mostly switch gears around 2.5k rpm n yes i m driving an auto gear box and there is a way to do gear switching for waja auto.If anyone wants to know more or hav some doubt or u think i m wrong plz msg me or post here. I'll reply when i c some respond. Have a nice day counting ^-^
