Microsquirt not picking up NB O2 signal, Why?

Post by Norzilla »

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
