hey whats going on guys?

should the 02 readings automatically show up when i pull up the gauges? mine doensnt read anything for that. would this be because i dont use the stock o2 sensor, but anlog output from the lm-1 unit. and now that i think about it, would this be the cause for my smog problem (link bellow)? i think i need to do some more reading up.

There should be a guage O2 LHS displayed on 'Consult Guages View' after you connect to your ECU

This is a parameter which is read by the ECU and fed to NIStune.

If the O2 sensor input to the ECU is not connected or does not work then it should be reported as 0 volts

It will make your vehicle operate in open-loop running only from the AFR tables rather than maintaining stoich (14.7/1) and this also affect your smog readings

Make sure your ECU O2 sensor input is between 0 - 1.5 volts. Anything above this and it probably wont register properly with the ECU
