Wideband AFR

Neo187H

Running a wideband sensor do you run one for each cylinder bank or just the one on one bank? If running just one doesn't that kind of kill the purpose of the sensor in the first place?

Sorry for the very basic question, I wasn't able to find anything hitting on this doing a quick search.

Jordo!

The factory O2's are widebands, so all you need is a way to monitor them. You can do that with Osirus, or if you want to view it all the time, you can get something that taps into the OBDII port.

That said... why do you need it? Are you doing tuning? Planning on going FI?

The the answer to either is "no". you don't need it.

If you just want the info out of curiosity, you can get several different plug and play monitoring systems that will give you tons of info from the car's ECU in real time, including O2 data.

Look under tuning forum -- you just need something that plugs into the OBD II port with monitors/dataloging capability.

At this stage this is more curiosity than anything else but the plans are FI in the future which would include tuning.

Jordo!

I'd wait then because the tuning software and dyno shop will be able to give you that info, and once it's set, you shouldn't need to constantly monitor it (unless going boosted - then it's a good idea for safety to keep an eye on things).

Anyway, if you want to see what the ECU and O2's are doing, I'd shop around for a good OBDII port plug and play monitoring and datalogging option. There's a thread on here somewhere about a nice one that was reasonably priced -- search around under the tuning section.
