OK I've finally got my PLX wideband kit installed in my 2003 Silverado SS, I only got the sensor (no guage) as I will be hooking it up directly to EFILive for logging/tuning. I placed the O2 sensor in the rear O2 bung on the driver's side exhaust (cats were gutted long ago, were cool :D) and the control unit is mounted inside the electrical center underhood - totally stealth! The trick part - I ran the two 5-volt analog wires through the firewall and soldered them to a 1/8" headphone jack and secured it to the plastic OBDC bracket, then I hooked-up a 1/8" headphone cable to the EFILive box so that when I want to log I just plug in to the "wideband jack" :notacrook: Well I thought it was a cool idea... total cost at Radio Shack = $6:

So far works great, to test last night I just idled the motor to get a reading and noticed that the commanded AFR is 14.6 but the WB is reporting 15.1-15.2 AFR :Eyecrazy: I'm not sure if there is actually something wrong with the tune or if the wideband is not hot enough? But this was 5+ minutes of extended idling so I dunno, any insights you guys have I'm open to.
Time to start tuning!
