O2 sensor

Post by MMamdouh »

is it possible to play with the O2 sensor signal to lean/rich the mixture? if the answer is yes then got any suggestions on how to do that and what signal values will give what effects??

well O2 sensors only regulate the AFR when the car is in close loop

this means that when it uses the O2 for AFR is when u r cruising

when u are full throtel it runs in open loop there is when the piggybacks come handy

they alter the MAP sensor signal used for AFR when it is in open loop
