Thats false information. The ECU's Rom file calibrates the Sensor for exhaust backpressure. The Sensor itself has a bottom edge limit of 11 to 1. The Sensor is very acurate up until that point.

I would be interested in a Utec logger that would pick up the serial input from a second com port to read WB data into the logs. I have a Rom file for the LM1 Wideband that gives you that output on the Serial. It works with Delta dash and the Flash program for ECUtek.
