is this possible? i dont want to invest in a wideband, but instead use my existing O2 sensor and read it through Hondata. i have a S300 chip, is this possible? i did some googling and returned with nothing. Thanks!

 

its impossible to interpret a/f through a narrowband sensor.

 

correct. you can log/display a/f readings only by using a wideband and running an input to the ecu. with hondata you would want to use the ELD (D10)

 

what wire would i run to d10 from the O2?

what wideband do you have?

 

get the PLX M-300 well worth it.
