I have read a pile of threads on how to make the reading from the LM1 and TS align. Here are a few data points:

With AFR at 14.0, voltage to TS is 3.3-3.5 volts
TS reads 16-17 afr
I have run the "Calibrate AFR" process

If I understand correctly my voltage should be close 2.45 at 14.0. I attempted to access the LM1 with the software and set it up differently but I cant set the lower end correctly for the calibration. Any suggestions? I think the issue is the LM1 is not sending out the correct voltage for TS to read.

Sorry for the re-tread of a questions but I could not find the solution.
Thanks!

How is your LM1 grounded?

If I understand correctly my voltage should be close 2.45 at 14.0.

I don't think that is correct. Actually 14 afr should be ~1.98 volts. 2.45 volts would be ~15 afr.
14.7 afr = ~2.35 volts.

Be sure that your LM1 calibration matches the calibration table used in TS.

I was careful to get power and ground from the same place as the MS. I used the alligator clip method I read on here and have the + clipped to the relay board key on power and the - is clipped the my ground junction for all engine/MS grounds.
