This is our most recent interface device designed specifically for tuners. When used with the VCM Suite of applications, the MPVI3 provides the most inclusive scanning, logging, and calibration package in the industry.
Using the MPVI3 with our TDN app for mobile devices, vehicle owners can read and scan their vehicles and then exchange the necessary tuning files with their selected tuner, whether the tuner is nearby or on the other side of the world.
REGISTRATION AND VERIFICATION
The MPVI3 is designed for enthusiasts and professionals to enhance every aspect of their vehicles performance.
Before using this product, you must register your MPVI3 and verify your use of the product. See Registering Your Device for instructions.
If you are using MPVI3 with the VCM Suite, you will need to register the device with HP Tuners. This allows you to purchase credits and additional features if needed.
NOTE: If you are using your device with the TDN App, your selected tuner may purchase credits for you.
The following instructions will walk you through the registration process:
NOTE: If you have registered multiple devices, look for the new device's serial number in the column on the left.
Port | Description |
1 | OBD-II Connector. Attaches to the OBD diagnostics port on your vehicle. See Connecting to a Vehicle for more information. |
2 | M8 Connector. Used to connect additional sensors and CAN bus inputs via the ProLink+ cable from HP Tuners. See Pro Link+ for instructions. |
3 | USB Type C interface. Used to connect to a Windows-based PC or laptop. Use of a high quality USB cable, such as the one included with the device, is strongly recommended. See Connecting to a Vehicle for more information. |
WHEN USED WITH VCM SUITE
When used with VCM Suite, a USB connection to your PC is recommended:
NOTE: See the VCM SUITE GETTING STARTED GUIDE.
WHERE IS MY OBD DIAGNOSTIC PORT?
On most vehicles, the OBD diagnostics port can be found on the underside of the dashboard (instrument panel) on the driver side of the vehicle. But, the location varies from vehicle to vehicle. Consult your vehicle's owner's manual for the exact location of its OBD diagnostics port.
A 20A maximum size fuse is required ahead of the unit. Consult your vehicle owner's manual for the location and rating of the OBD port fuse.
WHEN USED WITH THE TDN APP
When used with the TDN app for mobile devices, the MPVI3 connects to your mobile via Bluetooth. The app provides on-screen instructions for establishing the connection and attaching the device to your vehicle.
NOTE: See the TDN APP USER GUIDE.
Below outlines the legacy features on the face plate of the MPVI3, with a detailed description of each LED RGB (red, green, and blue) and bluetooth status icon.
When over-voltage is detected, the RGB Status LED will become solid red and will remain solid red until voltage drops below 15.5v, then it will go back to solid green. Operating the MPVI3 with voltage over 15.5v can cause damage to the MPVI3.
NOTE: When an over current is detected, the firmware cycles three times by turning the bus OFF and ON to see if current is below threshold. If any of the three attempts comes back reading adequately, the LED turns red only, after the firmware has used all three tries and the current is still high. Only a power or OBD reset will let the MPVI3 recover from this state.

This button can be used to connect your bluetooth device to your MPVI3. This button can also be used to start and stop your standalone data logging.
After unboxing a brand new HP Tuners interface device, you will want to make sure it is up to date with all of the latest files and firmware. The following steps will help you get started with your device and will also allow you to resync to get the newest updates.
When used with a computer running Windows 10 (or later), the MPVI3 is a completely "Plug and Play" device. You do not need to manually update its drivers.
Pro Link+ is a cable that allows additional inputs to be connected to the MPVI2+ and 3 for enhanced data logging. This allows you to see these additional signals in VCM Scanner, potentially providing critical insights into how your tune is performing. This includes:
A license for the Pro Feature Set, which adds software support for attaching external inputs to your MPVI3, is included in your purchase. However, the Pro Link+ cable must be purchased separately.
To order, go to https://www.hptuners.com/product/pro-link-plus/.
Up to two analog inputs can be added to the data stream received by MPVI3. Such connections use the following wires on the Pro Link+ cable:
Wire Color | Description |
Black | GND |
Red | Analog 1: 0 - 5 V, 100 Hz Sampling Rate |
Blue | Analog 2: 0 - 5 V, 100 Hz Sampling Rate |
Follow these instructions:
Messages from a 500 kbps CAN bus can be added to the data stream received by MPVI3. Connections of this type use the following wires on the Pro Link+ cable:
Wire Color | Description |
Orange | CAN High |
Yellow | CAN Low |
Follow these steps:
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 MPVI3.
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:
