Haltech A/F ratio Display on V1.89 E8
My issue still is that it is only giving me a 0-1 volt log reading. According to my logs 0.4 volts = 13 AFR (gas). Have you checked to see if the readings actually make any sense as mine don't. The WBO2 input is a 0-5 yet it comes out as 0-1 and is definitely not a lambda output.

I haven't tried yet under 1.89 and 35B, but in 1.71 installs I have wired a WBO2 to the a/d1 pin and a narrowband O2 to the O2 pin and all has worked.
It is pin, uh, 13 on the small connector (right next to the O2 pin).
I always took the greyed-out a/d1 configuration to mean "0-5V WBO2 only"
I have a couple of clients running this way, I don't know if they have upgraded to 1.89 yet.

On the E8, the O2 sensor input wire is pin12 on the 26 pin connector. On an E11 Spare A/D 1 is pin 13, the O2 sensor input isnt related to the spare a/d wires.
Its possible that the Spare A/D 1 channel in the E8 is taken up by the internal baro sensor.
In the past, the O2 sensor was responsable for the closed loop duty, and could only work using a narrow band signal. With v1.89, closed loop is now supposed to work via Spare A/D 1, or 2. I would stick with channel 2 since its on both the E8 and E11 and try it there.
