TechEdge WB O2 unit
Anyone running a sensor on each exhaust bank employing a switch/relay to read one sensor at a time? Pros/cons, any opinions?

Re: TechEdge WB O2 unit (GRX)
I have one in my exhaust that is located across from the H pipe so it get a sample from either side in theory. Never new they had one with 2 sensors. keep in mind these sensors are about 150-300 bucks depending where and when you buy them. Two would get expensive, and is mostly overkill.
Love the unit though.

I have two. One I bought for use and one for backup. So I was thinking I could use 'em both and emply a switch of relay to toggle between both.

Re: TechEdge WB O2 unit (GRX)
I think the biggest challenge would be supplying power to both sensors all of the time for the heaters. With those sensors, the heaters have to be on while the engine is running or it reduces sensor life. (Definitely double-check that, though). The control unit supplies enough power for a single sensor, so you'd have to modify it to handle 2 (or create a second power source). You can eMail Peter at Techedge -- I'm sure he's had that question before. He's usually pretty good about responding relatively quickly, especially to customers.

No, but the sensors must always be powered, and the heater temp
control is very important, so you need two controllers for two sensors.
No heater means the sensor will clog up. Unregulated heater means
the sensor may get too hot and expire.
> Is shielding critical regarding the cable?
To some extent - we have a well shielded cable - others don't.

I just got my TechEdge version 2.0. I won't have any time to get it installed for quite awhile I'm afraid. I also think that you can't mount the sensor in the H pipe because there is no flow in there. That according to my mufler expert here.
