I am about to receive kpro in the mail and my o2 sensor if giving me a check engine light. I checked it and the comp says that both sensors are bad. My question is will you be able to datalog with bad o2 sensors? Also i have a friend with a ep3, will it be possible to borrow his and use it to datalog? Are there any other o2's that are compatible with the rsx-s o2? My pockets are def. short after purchasing kpro.
