LM-1 Firmware upgrade... require O2 recalibration??? Anyone know if I'll have to recalibrate my LM-1 if I do a firmware upgrade?
I'd like to apply the latest firmware, but would rather not have to do a free air recal...

You are correct..
I have been calibrating mine the lazy way lately. I will get in the interstate and run up to about 80mph and let off the gas and coast. Within a few seconds DFCO kicks in and the AFR goes to 20.9 and I hit the re-cal button on the LM-1. The recal is complete and I did not have to pull the sensor.
