    ok i figured out that d13b has a 1300cc engine displacement compared to 1500cc of the d15b... so i guess d13b consumes less fuel that the other engine in question...^^ but i also read about the d15b 3 stage vtec engine... so now im an getting more confuesed...haha

    a D13B-4 or PH13Z JDM engine has 1300 cc displacement, it can go as far as 16 Km/Liter highway on a stock unmodified engine, mine goes beyond the stock mileage read at this thread for more details >>> https://www.istorya.net/forums/automo...fficiency.html maski unsa-on pa ug set sa D15B VTEC engine mas kalas gyud gihapon siya kaysa D13B...

    nya sa man bro? atong i-lean burn mode? aftermarket na bitaw na imong radiator, for sure it can handle the excess heat generated sa lean settings...nindut na imo ma testing kay automatic, kita gyud diretso ang diperensya, it lowers the engine`s power a little bit but it saves gas on the process, nya you can always turn OFF the modification by just flipping a switch if you feel a need for speed, and most of all it cost only 100 php on the materials....

    Akong i-explain bro ha as simple as possible, atong makina kay PGM-FI (JDM) 3 settings na ang injection program ana sa injectors, Rich-normal-lean, lain2x ni ug amounts of gas ang 3 ka setting, it`s a time-based process, ang rich ang pinakadugay ug 12V hold sa coil sa injectors, meaning ubay2x nga gasolina ang musidlit sa rich mode, it`s being controlled by the ECU, inconjunction ani para makahibalo ang ECU kung unsay gikinahanglan sa makina inig operate niya are the TPS (throttle position sensor) drivetrain sensor, crankshaft position sensor, IAT (intake air temperature) sensor, Block Temperature Sensor, ug Oxygen Sensor, in lean burn mode, I`ved manage to fool the sensors para mu act ang ECU to just use the lean mode, meaning small amounts of gas ra iyang i-inject at all times sa combustion chamber, no matter nga naka first gear pa siya in automatic transmission, in exchange to that is a higher heat generated sa makina though in real world scenario murag isa ka guhit ra sa temperature gauge ang increase sa akong observation sa ako-ang unit, lesser acceleration tungod gamay ra man iyang gi inject nga gasolina pirmanente sa combustion chamber in theory and actual medyo hinay2x gyud but not noticeable sa stop and go traffic, pero kung imo gyung ikadlit diretso taas2x gyud siya ug seconds iha maka 100 KPH...

    malingaw lang ko ani nga mod kanang makadagan na ko ug 80 KPH @ 4 gear nga naka ON ang switch, i steady ra nako ang pedal, ikalit nako ug OFF ang switch mukalit sad ug utro ang injection setting ang resulta musalta sad ang acceleration mura pud ko ug naka NOS hehehe

    boss dili ba madaot ang makina kung musubra sa 1:15 AFR (super lean mixture)

    Siguro kung sa deserto nga lugar nya mag lean burn ka mu overheat gyud siguro, pero kung sa snowy countries sure ko di gyud ka overheat, maski diri sa pilipinas nga minimal ra kaayo ang temperature fluctuation, so far wa pa man sad mada-ut ako-a bro, and I also observed some vehicles nga gipang convert ug ALTO nga carburetor to save gas, that`s the same principle sa akong gibuhat (Mechanical Lean Burn) pero electronic method lang ang sa EFI system.

    Kung air cooled engine nya i-lean burn medyo init2x gyud ang makina bro pero hantud karon wa pa man gyud mada-ut akong honda motard nga grabe kaayo ug gipang usab sa makina nya super lean burn sad....
