Hi,
I have been having a weird issue with my spartan 3 lite hovering around 1.15 lambda with little fluccuation and comparing this to the dyno lambda where it was rich all of the time. I have had the sensor and controller for a few weeks now.
I have confirmed the sensor setting is correct LSU 4.9
I wanted to complete a free air calibration to see if there was an issue.
When completing the free air calibration I got a calibration value of 340282366920938480000000000000000000000.000000 which doesnt seem to be correct or reasonable. I also get the same calibration value if the sensor is disconnected.
What is my issue here? Sensor is damaged? Bad wiring?
