Sal,
Just to confirm.
Rewiring the AEM white sensor wire to the factory O2 harness connection and changing the switch setting (position 4) on the back of the gauge provides the correct 0-1V signals for proper DME operation.
... and the gauge still displays accurate A/F ratios throughout the wide band range. Have I got that right?
I asked someone at AEM (or a 3rd party salesman) awhile back and they said "no".
Thanks
