Video: Setting Up HP Tuners To Log Your AEM OBDII X-Series Wideband

When it comes to tuning an engine, your combustion chamber is nothing more than an empty cylinder without introducing air, fuel and spark (and compression of course). And finding the right air/fuel ratio to produce the best power at the right cylinder temperature is commonly achieved with a high quality wideband oxygen sensor and controller, like AEM Electronics‘ latest X-Series wideband.

For factory ECU equipped cars using reflash software like HP Tuners, the most common way to get your aftermarket wideband to communicate with your laptop for tuning and logging was through the use of the MPVI Pro interface or a serial-to-USB adapter. Sure, this serial connection may have gotten the data onto your computer, but only after having to manually set up the voltage offset table for your specific sensor and controller, then having to live with data coming in at a much slower sample rate than most tuners really need.

AEM’s new X-Series wideband eliminates this sample rate handicap by ditching the serial connection as the primary data source, and instead utilizing an OBDII pass-through connection to eliminate unnecessary wires and increase the sample rate ten-fold.

 

Now, you’ve got your X-Series wideband installed and wired, but have no idea how to get the signal from your wideband controller to the logging software within HP Tuners. Well, have no fear because AEM’s own Beau Brown created the video above to walk fellow DIY enthusiasts though the process of setting up their OBDII X-Series wideband. If you follow this simple three and a half minute video you’ll have your pass-through wideband running seamlessly with HP Tuners’ reflash software, and at a much snappier sample rate.
