o2 sensor n emanage

[qj3]

hi all sifu,

o2 sensor will read the air after burned with fuel in combustion chamber n send the signal to ecu, then ecu read it whether its rich or lean.after that ecu tells the injector o inject the correct amount of petrol rite to make it stoich rite?

i heard if using emanage we can set the proper fuel on certain rpm during the dyno test.so my question is if the o2 sensor help ecu to get the correct reading to inject correct fuel amount, why is it we need to tune up the emanage again? will their setting clash?or if we already have emanage we dun need o2 sensor anymore? or o2 sensor not reliable on high rpm thats why need to tune emanage?

bro,if u fix a emanage u can set your own ratio now the stock from ecu one is set by your own,so whether u can set more fuel when race or more air when driving,o2sensor is only detect the lean or rich,emanage u can set your own ratio
