What we change on this platform

The 9-speed crossover platform. We have a working setup — firm shifts, on/off converter lockup, a sequential 2-3-4 instead of the factory 2→4 skip — and we're collecting logs before we open it up.

What your truck needs first

By model year, from HP Tuners' current support list. This is the owner's side of the job — interface, licensing credits, and any one-time module upgrade.
