Haltech E8 Narrowband Hookup Closed loop

E8 Narrowband Hookup Closed loop
For some reason I cannot get my E8 to display the narrowband input for closed loop correctly. I can measure the MV out of the sensor and it appears to be good but the indication always shows 1063mv.
I am using a stock single wire o2. Is there something I am supposed to program. On closed loop control which sensor do you select?
Thanks,
On a side note everything works great now. Just small bugs to fix!

Or do you mean I can use myWideband O2 Sensor on Analog Input 2. LOL. I guess I could try that. No use having two sensors connected into the car.
When I measure the haltech wire not terminated to the 02 sensor I measure 1.6V?
thanks,

Ok, you should be aware that the single wire O2 sensors work by heating up with the exhaust flow and until they reach about 700+ degrees F they will not read right. You can connect this single wire onto the dedicated O2 sensor input of ANY haltech and it will read, the problem is that they are worthless for accuracy. The best narrow band sensors to use are 3 and 4 wire sensors that you can also hook up directly to the haltech, all they need is 12V, ground and the signal goes into the O2 signal input wire.
There is a diagram on how to connect O2 sensors to Haltechs on every manual, have a read through it.
But, since wideband kits are so cheap now, you are better off using those instead.

I will just use my wideband input as slo suggest. It just didn't cross my mind to try this.
thanks guys.

What I am saying is use your WB O2 sensor that you allready have hooked up. You choose which O2 sensor to use in the Closed loop config page.
Next by using a WB instead of a narrow band, using 7.1 opens up the possibility of doing really cool things with the Closed loop by map function. A rotary will run really good up to and beyond 17-1 AFR in the 3000 + rpm range at low load with the right amount of advance and split. I am seeing well above 25 MPG on the freeway.
A WB can also run closed loop at idle, which a narrow band can't do because no pre renesis engine can run stoic at idle...
