Microsquirt not picking up NB O2 signal, Why?
Posted: Fri Sep 25, 2009 1:50 pm
Hi All
i have a newly installed Microsquirt with 2.89 code. I have an issue with the unit not reading the O2 signal.
What i have checked;
1) When the sensor is warm after 1-2mins with ignition on, i get a small fluctuating voltage across the signal and sensor gnd wire of between 0.03 and 0.08 volts
2) obviously the heater is working as the sensor is warm
3) I have continuity of the Signal wire from the sensor connector to the Microsquirt connector pin
I have checked in megatune and have the EGO setting to NB , i have set the target voltage to 0.45volts and then in the AFR calibration section have set to Narrowband and hit ok.
I am still not getting anything....
Does anyone know where to start problem solving this issue?
Thanks
John
