HP Tuners MPVI4 Interface & Credits
HP Tuners' MPVI4 is the interface that connects your laptop to your vehicle's ECU/TCM for tuning and diagnostics. Tracy Lewis Performance offers the MPVI4 device on its own or bundled with universal credits, which unlock additional vehicles or control modules within the HP Tuners software.
Available Bundles
-
MPVI4 — the base interface device.
-
MPVI4 + Universal Credits — bundles ranging from 2 to 20 universal credits, sized for anything from a single additional vehicle to a shop running multiple builds.
Universal credits are used across HP Tuners' supported platforms, so the right bundle depends on how many vehicles or modules you plan to tune.
