my b16a fuel consumption

[audiolizard]

im currently using a b16a engine..
so i test my fuel consumption, with shell(not V power) or Bhp.
i just found out that my car full tank is around RM70-80 i think.
the question here is, when my fuel gauge reach almost to the bottom part,
my car just clocked on 250-270km. i dun think it can even reach 300km.
is that normal or its rediculous? the fc is a huge different to me since im driving Myvi for last time.
any 1 can share their opinion here?

sorry i dint state that im a manual tranny.
and my head is b16b type R head( does it afflect the fc?)
so what would de problem might be?

my exhaust pipig to large?
my ECU had tune by the previous owner, he state that the car is very jimat minyakk but what i saw is different..
or mayb i need to overhaul the engine? bad digest system i think?
should i bring it to my mech? can he check it out for me what is going wrong? thx

I used to suffer this dillemma.... My B16B clocked not even 300km on a full tank... This only with occassional drag, which is ridiculously high FC for a 1.6 engine. ( However, i do realise much of my FC is based on my right foot, =.= )

After changing a few items and make some changes to my driving style.. i had achieved around 380km for city/town driving and 450km for highways on a full tank... (shift early, light throttle. Doesn't mean u drive like a slow-poke laaaa, just increase ur speed slowly instead of vtec-ing all the way)

My changes;-
- ngk iridium sparkplugs (did u change ur's yet???)
- service as in changing the engine oil, etc
- ron97 (this is probably the most significant improvement on my FC. While using RON95, I only suffer a little in accel but the it kindda consumes more petrol. Once change to RON97, there's an improvement on my FC)

Based on city driving with traffic lights, etc etc
RON95 - around $0.26 per km
RON97 - around $0.20 per km

(while on RON95, i need to try harder to hit the figure of 300km on a full tank. But with RON97, i can achieve 350km easily)

This is just my case and my observation on my car, as i reset my mileage everytime i fill-up. I'm not sure whether my opinion will help u... cheers

my setup is just like yours...b16a+pnp head and ctr cams...full tank my b16a manual can go about 400km on highway + stop n go at traffic lights...watch ur right foot bro...drive slowly...no need to speed when driving at town....and no need to compare to myvi la...is like comparing 170hp vs 90hp....

 

[skalock77]

Vtec open more mean more fuel consume...hahah......if u drive normal (no open vtec)....i think u can achieve it....but if u drive slow also consume more fuel...then u have to check ur car

 

[deathzone]

I think Driving style and regular maintanance is important. Btw my ek4 can go around 400km in 1 full tank.

 

[220mph]

im not a vtec owner though.
but 115whp campro and altezza owner.
anyway just to share.
if keep reving till wheelspin on 2nd and 3rd gear, fc for campro rm75=300max. altezza rm 100=400max .. but if drive with drive conservatively. daily from old klang road to TTDI and back + traffic jam. 500km for campro easily, 600 for altezza ..
i think that sums up the story lo.
infact i've tried to get record millage with my campro. done from here to penang on a 5am morning journey. no jam etc. with empty tank of fuel pump in rm70 . get 650km millage. believe it or not. lol..
therefore i think , controling our right foot is the best fuel millage substance

hmm. okay btw does throttle body afftect FC also? mine already change to racing type de..
and my car also same like u 170hp on road.
yea i admit i bang to redline several times on highway yea and vtec open i mean....
nothing to do i guess but to refill the oil tank and try for 1 more week. lol.
yea its stupid to compare with MYVI but hell yea myvi is great saving oil car haha..
il repost when i get the results thx to all ya!

 

[rodcyprian]

My B16A full tank can drive up to 350km with every vtec always buka.
But if not playing with vtec can reach more than 400km.

Just a sharing,
Two years back when I ask my friend send me using his Myvi 1.3 manual to take my new car, Toyota Wish 1.8 auto. We both car try to fill up full tank and drive back home about 250km, and refill again just to test the fuel consumption. And the result is 15litres for Myvi and also 15litres for Wish.
My point is I still think Myvi is not that fuel economy. Fuel economy still go to Honda City/Jazz or Toyota Vios/Yaris...

 

[kangyoon20]

my b16a standard manual RM10 = 40-50km either vtec every gear or slow drive
full tank about RM70 also will not reach 400km :(

only mod open pod and exhaust....

I think all B16A is about like that! With or without On air-con also!

bro kangyoon and other bro's...

for city driving,i think 350km-370km should be considered alright...cause our gear ratios also can play a role....5th gear RPM3000 below 100km/h or near....

anyways...for improvements you guys can consider using VAFC and send your car for tuning...there should be improvements not only in performance but for FC also.....

don forget also depends if you have rechip your ECU...some chips like mugen tends to be a little too rich below vtec point.....

yup. my car was running rich, not at vtec, on startup also rich already. drink petrol? okla, full tank can get me approx 300-320km....

changed back to my previous chip, can get me 350-370km... depending on the drivers mood too..

 

[AD_EG]

yeah bro...some chips is like that....

but don worry...your FC will be sweet once the piggyback comes in ..hehehe...

 

[kangyoon20]

i wan hondata, but damn exp
i wan neo, still no budget

can EK4 OBDII rechip?
or still need to get OBDI ecu?

u still need OBD I.

however u can get the converter harness... then get an OBD I and CHIP ITS MAMA!

hondata is exp, but rmb.. u get what u pay for! cheap things aint good and good things aint cheap!

ad_EG: WAHHHH SO PUBLIC MEH! top secret mod tuh!

ad_EG: WAHHHH SO PUBLIC MEH! top secret mod tuh!

tats wat i am wondering
OBDI ECU RM500-700
OBDII>OBDI harness RM300-400

might as well get a second set of neo or vafc directly?

 

[arrowhead]

well, let me assure u, rechip isn't as "great" as you would imagine. it'll actually take u some time and money to find the right chip.

i myself have changed like, 4-5 chips already. somehow or rather, they tend to give me problems (like my engine jerking problem - if u read it before on honda thread) change chip, everything ok.

even bro AD_EG also had problems with his chip. so its not like a 100% good thing. its just a cheap way out, if u ask me.

ultimately, get a piggyback or standalone if u can afford. satisfaction guaranteed. and u can sell it in the near future. market value is always there.

let me just share wtih u a bitter experience i encountered, in fact, im still facing it.

changed chip cuz previous chip causes engine to jerk when pedal to the metal.
used new chip for awhile, engine pinging, went to adjust ignition timing, adjust till MAX RETARD (yes MAX RETARD) engine still pings.
headache, what 2 do? get myself another p30 ecu.
plugged it in, adjust ignition again.
everything ok till 2nd day, CEL came out. check code, TPS sensor (A#!$@#$)
adjust TPS, everything ok, another code came out... (something related to TCS- nvm not so important)
change back ECU to the "rechip" one, engine pinging.
change back to OLDER chip - everything OK... so far.. *touch wood*

Wahhhh i say you getting piggyback also you so scared meh ?

 

[arrowhead]

Lololol!!!!!

Why u tell everybody i getting piggybacccckkkk!

 

[AD_EG]

sorry ah bro...

yep bro thats wat my point is

even doing rechip for my ek4 also require around RM800-1000
as u said i need OBDI
for the same amount i can get second hand vafc or neo already wif flexibility in tuning

 

[deathzone]

Im using obd2 rechipped fine tune with vafc...can reach 400km-420km normal town driving without vtec open. If vtec open few times about 360km-380km.

 

[AD_EG]

the reason why ppl usually re-chip is to remove the Rev limiter....so if you don intend to rev pass 8.2k if im not mistaken...then don need to rechip....just get VAFC...

but not all chips are bad...i have tested a few...most of us are also using re-chipped ecu's....but for obd2 might have to think twice...like bro kangyoon highlighted...$$$

but bro arrow did face some terrible experience with chips...i faced one...but my case wasnt my chip that was the issue...it was my ecu...i changed the whole ecu....

 

[arrowhead]

my chip cap ayam surela liddat hahahahahah

 

[donCityZ]

You need to tune your fuel management using at least the VAFC. then you will get more mileage. any mods done to increase ponies, must be accompanied with fuel management, otherwise you get power, yeah, but at same time you'll lose fc.
