Hey Guys,

Simple question this time around: what is the difference between AFR and AFR Adjusted as listed in the data list?

On older applications it was noticed that the reading from the factory wideband was off at richer values, so that's an adjusted representation to factor into your tuning.

Thank you. Just to clarify, that would make the adjusted AFR the more accurate value?

Also, an additional question: when you select "show percentage difference", what value is that a percent of?

If you have not verified that yours shows richer just use the standard one.

Set in preferences.

thank you. my AFRs do show up richer on the raw value, so I'm going to assume the adjusted value is what I'm meant to be using (EXAMPLE: 8:1 WBO2 vs 10:1 ADJ. O2)

as for the preferences, I'm guessing the values for "below", "untill", and "anything above" is pressure in mBar, correct?

Those will always, I'm talking about comparing to an external wideband.

mBar.
