Hello all,

Newbie here. I'm tackling my first tuning experience today and have run on an issue with data logging my wide band. First I purchased the PLX300TE and as luck would have it, the unit did not work directly out of the package! Given the circumstances, I aborted that mission and configured my HP Tuners for an AEM air fuel ratio gauge that I had in stock. Now, I saw that AEM was listed as a supported unit, however I can not get HP to recognize the gauge. I've switched from the #1 & #2 pins on teh MPVI, with no luck. The analog wire from the gauge is registering about 1.54V. But when I attempt to scan all I've got is a flat line. Any help is greatly appreciated.
