I think u need to start think more simple. Hybrid car is naturally fuel saving and was created for fuel saving purposes. No need to go so detail bout KM/H and RPM or DCT function or nature or character or wateva to be honest.

The car is high tech enough and the ECU is smart enough to calibrate and learn your driving pattern to suits your driving style.

And every car/brands/model peed (in meter not sure bout OBD so no comment on OBD) varies from each other. And I've tested same Garmin GPS device driving in the same car but the KM speed is slightly different by bout 2KM - 3KM and the different is so marginal.

Engine RPM also doesn't determine the shifting timing of any gearbox even in DCT. It still depends on the method or the reassure you put on the pedal gas/driving pattern.
Eg: If you drive gradually slow from 0KM - 60KM, the gearbox will shift maybe from 2nd gear to 3rd gear at their optimum level RPM, lets say bout 2K rpm (Example only). But if you drive aggressively 0KM - 60KM, the gearbox might not shift from 2nd gear to 3rd gear at 2K rpm. It might shift at 2.5K or maybe 3K or higher.

In conclusion, every car/driver got their own style and road to drive. A lot of factor whether is internal or external determine the fuel efficiency of a car and its very difficult to judge. So the 5KM variation from speedo meter and OBD doesnt give any much different.

Dont judge just based on the readings by 6% - 9% bro, end of the day only 5KM variance. Percentage doesnt respresent everything. 5% of RM100 is small amount compare to 2% of RM100,000.

Can you even save 30KM per full tank by driving your method? Is it justifiable?

I drive Jazz pre-FL 2016..if seldom tekan can reach 580KM - 600KM..if always tekan 500KM - 520KM

No fuss bout it. Cheers bro

how many percent highway to get this 580 km? 100 percent highway? i usually 75 jammed, 25 highway : only get 450 KM haha

I usually 95% highway 5% city. Usually go to work very early no jam, leave work either very early or very late also no jam ...weekend use other car

Usually i drive moderately around 80km - 90km only...sometimes tekan up till 110KM - 120KM

My fc sucks lol 

Highway 30% city 70% and i always speed the car to the max when i'm on highway.

And also bcoz i changed the rims from 15' to 17'. Sacrifice fuel consumption but improve handling/stability 

I dont really speed this car as I dont feel safe above 120km..feels shaky above 130km to in my own experience..my max only bout 140km-150km a few times and I dont feel the car is in right stability..feels wobbly

Do you had bodykit on your Jazz?

I feel a bit difference after adding modulo bodykit, its much more stable on high speed.

Check your tire pressure maybe too high.

Weird if above 120km/h feel wobble. Mine always above 140 yet stable je

how much do you fill your tyre? 230 KPA front and 220 back?

Anyone encounter click sound when rpm reach 40 km/h each time you start driving

Hi All,
I am new guys here , will be collect my car next week ,

can i check what is the different between Modulo kit and Mugen Kit ,

and where can get a good lobang to install it?
