What your truck needs before we can tune it

We only ever touch the file. Everything on this page is on your side — the interface, HP Tuners' licensing credits, and on some newer trucks a one-time module upgrade. Check your platform and model year below, then order.

Ready to tune

Read the vehicle with your MPVI, order, flash. Nothing else to do. This is most trucks before 2019 and every GM T87A-equipped truck now that HP Tuners dropped the unlock requirement (Nov 2025).

Direct OBDII upgrade

A one-time upgrade you do yourself in VCM Suite with the interface plugged into the truck. The software walks you through it during the first write. No shipping, no removing anything. GM T93 transmissions on Global A vehicles (Mar 2026), GM 2018–2023 L5P engine ECMs (Jun 2025), and 2022–2024 Ram Cummins through an authorized reseller.

Send-in service

The module comes out of the truck and goes to HP Tuners (Buffalo Grove, IL) for a one-time upgrade, then goes back in. Typical turnaround is a few business days plus shipping; GM Global B TCMs run closer to two weeks. The module only ever works with HP Tuners' software afterward. You pay HP Tuners for the service and buy the credits separately.

Not yet

HP Tuners doesn't support the controller. We can't help until they do; leave your email and we'll tell you when it opens.

Interfaces

Any MPVI2, MPVI2+, MPVI3 or MPVI4 works for most of the list. The exceptions: 2019+ Ram Cummins, 2023+ Super Duty and GM T93 transmissions need an MPVI3 or newer; GM Global B vehicles and 2026 Super Duty need an MPVI4. HP Tuners ends support for the original MPVI on Jan 1, 2027. The RTD device works only for receiving tunes, not reading or editing — if you own an RTD, say so on the order form.

2018 and newer Ram, Dodge, Jeep and Chrysler also need HP Tuners' Dodge 2018+ Smart Access cable to get through the factory security gateway. Without it the interface can read codes but can't write.

Credits

HP Tuners licenses each module to your interface with Universal Credits ($49.99 each). A transmission module is usually 2 or 4 credits; a Cummins ECM is 6; a Global B Duramax ECM is 8. You buy them once per vehicle and can then write as many tunes to it as you want. We don't sell credits and never need yours — the licensing happens on your laptop.

If your truck needs a service

Do the upgrade first, then read the vehicle and order. The read has to come from the upgraded module, so there's nothing for us to tune until it's done. Two ways to get it done:

  • Do it yourself. Buy the service from HP Tuners or any authorized dealer, pull the module, ship it, reinstall it. We'll send you the removal and relearn notes for your truck if you ask.
  • Direct OBDII through a reseller. For 2022–2024 Ram Cummins the upgrade can be done over the OBD port by an authorized HP Tuners reseller instead of shipping the ECM. Email us and we'll point you at one.

Prices on this page are HP Tuners' list prices at the time of writing and change without notice. Confirm the current price and lead time with HP Tuners before you buy a service.
