i have a 2003 350z so im aware i done have the wideband O2 sensors, but what i do have is a Innovate LC-1...the DB kit. i will be installing that in this week and i also order the Osiris/Cipher product from Uprev but what i was wondering is since i will only have one O2 sensor, is that enough to do tuning with a/f ratio. i mean the log should show my a/f ratio so i just send that in along with the log from osiris and that can work right? anyone ever had this problem before? please help me

 

please someone help?
