OBD-II Devices

Some third party sensors attach directly to the vehicle's OBD-II diagnostics port and provide a pass-through connector for other OBD devices such as the MPVI4.

The AEM X-Series OBD-II Wideband AFR Controller Gauge is one such device which has generally performed well with HP Tuners interface devices. It can be purchased from our website here:

Although, the MPVI4 may work with other similar devices, we cannot guarantee compatibility with all of them. For questions regarding specific devices, please contact HP Tuners Customer Support.
