HP Tuners PROLINK+ Cable with Analog and CAN Bus Inputs - External

In this review of the PROLINK+ cable the bottom line is simple: this is a focused accessory for tuners and diagnostics users who need reliable external sensor inputs. The reviewer found the cable best suited to anyone using an MPVI3 or an MPVI2+ with the required Pro Feature Set, because it extends those interfaces with dedicated 0-5V analog channels and a CAN bus input at a consistent 100Hz sampling rate. It is not a general-purpose OBD2 adapter; it is a cable-only solution meant to add measured analog and CAN inputs to compatible HP Tuners interfaces.

Key Features

• Two 0-5V analog inputs: Provides dedicated channels for external sensors like wideband O2 or pressure senders so signals are read directly and cleanly.
• CAN bus input: Offers a 500kbps CAN input for integrating vehicle data streams alongside analog sensor readings.
• 100Hz sampling rate: Ensures frequent data updates suitable for logging dynamic parameters during tuning and testing.
• M8 to 5-wire harness: Uses a compact M8 connector to a 5-wire harness for a tidy, automotive-friendly wiring connection.
• Compatibility with MPVI interfaces: Works with MPVI3 and MPVI2+ interfaces (note MPVI2+ requires the Pro Feature Set), keeping setup straightforward for existing HP Tuners users.

Who It's For

The PROLINK+ cable is aimed at enthusiasts and professional tuners who already own an MPVI3 or MPVI2+ and need extra analog inputs or a dedicated CAN feed for logging and sensor integration. It is especially useful when installing an analog wideband O2 sensor or other 0-5V devices where clean, dedicated channels matter.

Those who should look elsewhere include users without a compatible MPVI interface or those who want a full multi-function scan tool; this listing is for cable only and does not include an MPVI device or software features. MPVI2+ owners must also purchase the Pro Feature Set to use the cable, which adds to total cost.

Pros & Cons

Pros

• Dedicated 0-5V inputs provide reliable readings for external sensors without repurposing other ports.
• Good build quality and generous wire length make installation easier and customers report it fits well for wideband O2 sensor routing.
• 100Hz sampling and a 500kbps CAN input deliver timely data for tuning and diagnostics.
• Compact M8 connector keeps the harness neat and automotive friendly.

Cons

• Requires a compatible MPVI3 or MPVI2+ with the Pro Feature Set, so it is not plug-and-play for all users.
• It is a cable-only product, so buyers must already own or purchase the MPVI interface and any software upgrades needed.

Our Verdict

The PROLINK+ cable is a practical, well-built accessory for HP Tuners users who need clean external sensor inputs and CAN integration. Professionals and serious enthusiasts with an MPVI3 or MPVI2+ (with Pro Feature Set) will find it good value for dedicated analog channels and reliable sampling, while casual users without the matching interface should consider complete scan tool options instead.

Frequently Asked Questions

Will this plug into any OBD2 port?
No. This is a cable-only accessory that connects to MPVI3 or MPVI2+ interfaces and uses an M8 to 5-wire harness rather than a standard OBD2 plug.

Do MPVI2+ owners need anything extra?
Yes. MPVI2+ interfaces must have the Pro Feature Set purchased to use the PROLINK+ cable.

Can it read wideband O2 sensors?
Yes. The two 0-5V analog inputs are suitable for external wideband O2 sensors and customers report the wire length works well for that use.
