quick AFR question

Which Wideband O2 and datalogger software are you using?

Wideband O2s output anywhere between 0-5v, each different voltage corresponds to a different ratio. e.g. 3.1v would be 14.6:1 while 2.8V would be 11.6:1 .

You could be seeing the voltage output?

My LC-1 Wideband can be programmed to a certain voltage range as well. This is useful if you want to simulate a narrowband O2 or have some bizarre logging requirement.

On my wideband, the output I use for my gauge is on the 0-5V range and the output I use for my twEECer is programmed to output in the 1v-2V range.

No problem man, holla back if you need any more help.
