    Wideband Compatibility

    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.

    Ok, I've got the MPVI programmed to the proper input and I'm able to run a scan log with some AFR values displayed. However the AFR is not inline with what is actual. Example at idle I'm reading about 12.80, while the AEM is 14.70. Any takers on help??
