Just wondering what set ups people are running? Not that many WB O2 gauges have dual inputs... So is it ok to just run off one exhaust bank (have just one sensor)? Is it effective enough?
I run one Wideband O2 sensor on the PS and it displays and records on my car PC. It gave the same readings as the dyno O2 sensor where the DS was monitored. If you need O2 sensor feedback you would need to install a kit that includes a narrow band simulator that connects to the ECU.
I am using two LC-1 Wideband Controller and XD-16 gauge for both dump. Only one output is being used by haltech ECU. http://www.innovatemotorsports.com/products/xd16.php
From my searching it seems most who have a single sensor run it on the PS. Though most report not much of a difference between sides, which is always a good thing Both the PLX and LC-1 set ups look good. I was also looking at Zeitronix as an option, with the control box. I also found a single guage with dual digital readouts for two sensors, but cant find atm.
I run the same as Pexzed and they can be wired in to replace the stock narrow band sensors. All equipment is provided with the sensor module to make it work which is essentially some wire and a resistor. PLX make the best gauge and sensor module by a long shot. They require no calibration and when you hook it up with the DM-100 or DM-200 organic LED display you have one of the best gauges available in terms of flexibility. PLX also have a USB module that plugs into the sensor module so you can datalog onto any windows PC running their software available for free download.
This is not quite relevant, and I'm definitely no expert: I've been running one dud O2 sensor and one good one for a few months. I thought there was no difference in the peformance, although one bank of injectors was always working slightly harder than the other. And on a long haul both O2 outputs went to 0 and sat there (which I assume means the car was running rich?). This week I replaced both sensors. The engine was immediately much smoother, the injector duty cycles now match exactly, and the O2's display correctly all the time. Should have fixed it months ago, and thanks again to ECUTalk!
