hi 20% low 10% throttle... you must have afr meter to change the value...

lean to rich

im already set my throttle lo 10% and hi 40%..

i dont understand to setting up the Air correction factor setting (Throttle opening, large / small) do i need afr meter to change the value?

the manual wrote that the correction factor is +10%, the ECU recognizes that
the air volume has increased 10%, so fuel is increased about +10%

i try increase the correction value to 15% at 4000-6000 rpm.. but still fill the same..my car still slow..
but i can hear the diffrent at sound of engine went i change the correction value at 1000rpm(stop car).. am i missing someting? or just my engine already rich the limit? coz all part in my engine still stock

try -10% then u might see power!. running too rich wont give u power. as i heard, below 3k rpm u can try set to -5 to -15% but depends on engine and modification. watch out for pinging.

that is just a trottle,the value at air map

tq so much...
and about the sensor type..
wat type i have to use? :hot-wire,flap,pressure,or karmen?

again,my car is wira 1.6xli soch..no bot..stock only..

and

wat the maximum correction value i can rich? from 4000rpm to 6400 rpm?

u must get ur initial setting right.
4 cyl,throttle up,sensor =karman ,in=? out =?(must be same follow manual)
and from there set ur throttle low and high %,normally low 20 high 50
it depend on ur throttle sensor and driving style.
and last set the +-%

tq so much...tq tq!!

get some friends together. gather some money to get a good wide band sensor.... then do some read up in the internet to get a rough idea on what kind of air fuel ratio u should run and start from there
