Question About O2 Sensor

[wishturbo]

Hello everyone,

I would like to ask something about o2 sensor. Currently my car was doing bolt-on turbo and everything is fine except Engine Check Light on. Once the CE light on, TRC and VSC system disable which I don't want it happened. I did system diagnosis and it detected as "Fuel too rich" from o2 sensor. FYI, the ecu no longer can control injectors since I'm using standalone ECU.

So, is there any way i can trick ECU from getting signal 'Fuel Too Rich' from o2 sensor? I already did sensor relocation and still no luck. Currently I still find the right voltage to do voltage mod. But seems it will fail :(

Could it be your O2 sensor faulty? What is your actual AF?

if i am not wrong.there is some kind of resistor that you can plug into the sensor plugs to trick the ecu .i have that problem too initially.but all was solved using that small resistor .
