350Z Kiwi PLX Data Logging?
Hi All,
I bought a Kiwi PLX OBD2 Bluetooth unit a couple of months ago. I have been watching the customizable gauge displays with interest. I put up the ones that show O2 sensor voltage in the Cats on both sides of the engine. The O2 Sensor 1 - 1 reads about half what O2 Sensor 2 - 1 reads. Take a look at the attachment if you like. Seems to me they should read pretty close to the same. Mind you the car is not throwing any ECU codes. Nissan service reps locally tell me that I shouldn't worry until codes appear. Kinda seems silly to wait until a code happens before taking action. If you have a way to catch a problem before it leaves you stranded somewhere why not take advantage of it.
See attached Log file below.
If anyone has a similar experience please reply to this post. Just curious what you are seeing out there and is it the same as what I am seeing.
My car is very lightly modded. Cold air kit (JWT Pop charger), Samco Silicone intake hose, Z1 silicone PCV and water hose kit. Not enough to do anything to the engine other than let it breath better.

Your car's not lightly modded. It's stock. My car is lightly modded. Motordyne TDX shockwave exhaust with ART pipes, motordyne 5/16 isothermal spacer, Stance Pro Comp coilovers 19X11 22 offset rear 19X9.5 18 offset Avant Guard wheels & an Uprev Osiris tune. Boom.
You replaced a house & some silicone? What? There is this song by Sir Mix A Lot called "My Hoopty" check it out.

It's sensor 1 bank 1, sensor 2 bank 1. The voltage on sensor 2 should be half of the upstream sensor 1. They are on the same bank. One is in the header & the other is at the cat.
