I feel a little dumb asking the question but... on the EEHack dashboard you have your target AFR and the WB AFR readout. Target AFR is usually 14.7 while cruising or not in PE mode. Is the WB AFR number the calculated AFR that the sensor is seeing or is that the "setpoint" that is trying to drive the BLM?
For example if the WB readout is 12.5:1 and the target 14.7:1 is the PCM trying to add fuel because the car is running lean? Or is the O2 sensor reading rich and the PCM is trying to lean out the ratio.
