Innovate Wdeband Problem - AFR=21.9 I have had the LC-1 for about 2 yrs and it has worked fine until recently. Now it works under part throttle, but at WOT at 4k RPMs and 6 psi boost it goes to 21.9 and stays there. The car still runs fine. Does the sensor need replacing?
Thanks
Chris

Try a free air calibration. If it doesnt fix it, try reflashing the firmware.
Then test for a bad sensor with some carb cleaner on a rag. Wrap the sensor, and turn it on... it should go rich. Otherwise, it is a bad sensor. There is also the possibility that the LC1 is bad. Mine went ****-up after one year.

Mine started f'ing up. I would have to do a free air cal to get it back. Then one day it froze at --- on the gauge. I tried to connect to it with the LM Programmer and it said LC1 not found. Took it to the bench, powered it with 12v, tried to reflash. Nothing.
I then bought an AEM UEGO gauge and never looked back.
