The name of the sensor required eludes me right now.. but it is "accurate" AFR readings. My understanding is LAMDA (which will be used without the addition of a sensor) is a calculated AFR. Otherwise the numbers will be off the sensors and even then some would be calculated. Example being Torque Pro. It gives me 0-60 ET and HP and Torque, but they are calculated. I just look at it as a means of a baseline and anything done to the car can be compared to that.
