what does this warning mean?
 

Warning: MSQ Units Mismatch for afrBins2! AFR found in current configuration, Volts found in MSQ, values were not converted to new units

you have an AEM WB and MS1.

MS1 and an LC1
I'm also getting the same warning for bin1

are you loading a tune and getting this error?

If I load a different tune or make a change off-line, then load the TS settings. It will pop the warning.

if you are using tuner studio sounds like your current settings are different then the tune's original setting. See what the o2 sensor setting is set to and adjust accordingly. that or build a new table using volts.

basically you loaded a tune that the was set for a different o2 sensor than your current configuration.

makes sense.
the backup tune I use isn't set for WB.
I'll go fix that
THX!
