How it works
Read the truck
Check what your truck needs — most need nothing, a few newer ones need a one-time module upgrade first. Then plug in your MPVI, read the vehicle in VCM Suite and save the .hpt file. Your interface, your license.
Start an order
Pick your platform and package, upload the file, and tell us what you want changed in plain language. Pay on Stripe's secure page.
We tune it
Your file goes to a tuner who rebuilds these transmissions for a living. Within one business hour you get the tuned file and a written list of exactly what changed.
Flash it, drive it
Write the file with your MPVI, reset the transmission adapts, drive it. If anything needs adjusting, send a log — one revision is included.
Reading the vehicle
Plug your MPVI into the OBD port, open VCM Suite → VCM Editor, and choose Read Vehicle. Save the file somewhere you can find it. If your truck needs a one-time module upgrade (check here), do that first — the read has to come from the upgraded module.
After you flash
Write the file the same way you read it, with the battery on a charger. Reset the transmission adaptives if VCM Suite offers it for your platform, then drive gently for 20–30 minutes so the controller relearns. The first few shifts may feel different while that happens.
Revisions
Every order includes one revision within 30 days. From your order page, tell us what you feel and attach a short VCM Scanner log if you have one; we'll send a revised file, normally within a business hour.
