Hello,
Newbie vems user here. Got vems installed, and the car is running. However, I am unable to calibrate the wideband O2 sensor with vemstune. The sensor seems to be working properly, and I get plausible lambda values. When I go to the WB O2 calibration window, the value is always 0.5, regardless of the calibration value, and regardless of whether the O2 sensor is installed in the manifold, or out in "free-air". Thanks.
