I've been trying to use Tuner Studio Analyze Live and I keep getting O2 out of range. Doing some reading I saw where you could use the Calibrate AFR tool to specify your 02 sensor and I thought that might help. I have an ancient LC1. It had been giving me reasonable readings, typically in the range of 12-15 for the past couple weeks of tuning. When I used the Calibrate AFR tool, specifying Lc1-Lc2 (default), the O2 sensor started reading 20+ full lean no matter what I've done. I did a restore to previous msq from a few days ago, and that didn't help. I went in and recalibrated the Lc1 to insure it was set to 0v = 7.35:1 AFR, and 5v=22.39 AFR. Again, no help.
What would cause this weird behavior? How do I get back to where I was??
