Set to show a external wideband input via the eld pin. Log hits richest point at 12.47 when gauge goes richer to (12.47 on log and gauge can show 10.0-12.4 with no change to log). Has happened on a few different cars here is a log of a more recent one

What wideband are you using and what are the conversion values for the wideband?

Aem eugo, and a plx m300. 0V-10AFR
5V-20AFR

You should use a multimeter and see if the wideband controller is outputting voltages lower than the reading you are getting. This is more than likely an issue with the wideband being used. also make sure you have the correct voltage conversion for this wideband.

Did you remove the resistors in the ecu to allow the eld to read down to 0 volts?
