i have the haltech wide band controler. (innovates with the haltech name)
anyways i am getting a very low voltage from my sensor.
i see at idle anywhere from 70 to 300 Mv and under acceloration i will see at most 2500 MV.
both are dangerously lean a/f ratios.
i know my car is not running lean, because i hooked up to my 4 gas and i have high ppm of HC so i know i am running super rich.
i started leaning my mix based on the 4 gas readings and that brought my wide band voltage up.
i am also getting the same voltage on my labscope so it is not in my software.
i have calibrated the sensor twice with the led and there are no error codes

heres how i have it hooked up
brown 0 to 5 v signal wire to purple shielded wire ecu side
and in my settings i have my o2 voltage to 0 to 5 volts and set to bosch wideband

one other question is any one having problems running there wideband sensors in the stock location due to heat issues
thanks

I'm not completely sure I understand as I haven't fooled with the Haltech/Innovative controller. But if you're trying to hook it up to the Haltech to read the linear 0-5V+ output from the sensor then your low voltage reading corresponds to the mixture being rich and not lean. If you're trying to use a narrow band output voltage to tune you're greatly under-utilizing the product.
