Year And Platform
The year and make help narrow down controller support, tuning software compatibility, and whether the vehicle falls into a GM DOD/AFM, HEMI MDS, or cam tune workflow.

VIN Basics
What Does a VIN Tell You?
A VIN can identify the vehicle's model year, manufacturer, model line, body information, restraint system, engine family, plant, and production sequence. For tuning, the most useful pieces are the year, make, model, engine, transmission, drive type, and fuel type.
Engine Family
Engine information helps separate 5.3, 6.0, 6.2, 5.7 HEMI, 6.4 HEMI, and other combinations before you choose a tune package.
Drivetrain Details
Transmission and drive type affect how the tune should be scoped, especially when shift behavior, torque management, tire size, or gear changes are part of the build.
Engine ID
How to Identify Your Engine
The VIN decoder is a fast starting point, but engine swaps, previous repairs, and aftermarket parts can change what is actually in the vehicle. Confirm the engine by checking underhood labels, RPO/build codes, casting numbers, service records, and the stock read file when possible.
GM Trucks
Common tune paths include 5.3L, 6.0L, and 6.2L LS/LT combinations, with DOD/AFM status and camshaft details driving the correct package.
Dodge And Ram
HEMI vehicles often need confirmation of displacement, MDS status, camshaft, VVT status, transmission, and controller support before tuning begins.
Stock Read File
The stock read is the final calibration source of truth. It lets JR Jones Racing see controller, operating system, and file information before building a tune.
Tune Match
Choosing the Correct Tune Package
Choose the package that matches the actual hardware on the vehicle. A delete tune is for completed cylinder deactivation delete hardware, while a cam tune needs cam specs and supporting mod details. When the build does not fit a preset product, use the builder or contact support first.
DOD / AFM Or MDS Delete
Use these packages after the mechanical delete parts are installed and the calibration needs to stop commanding cylinder deactivation.
Cam Tune
Use a cam tune when the camshaft has changed or the build needs startup, idle, airflow, fueling, spark, and drivability calibration around the new cam.
Custom Tune
Use a custom tune when the vehicle has mixed modifications, swap details, injector changes, converter changes, tire or gear changes, or uncommon requirements.
Tune Files & Cam Kits
JR Jones Racing Tune Files & Cam Kits
Use these tools to confirm your engine, drivetrain, tire size, gear ratio, or RPO codes before ordering. Once you know what you have, JR Jones Racing can help match your vehicle to the correct tune file, camshaft tune, DOD/AFM delete tune, MDS delete tune, or cam kit.
FAQ
VIN Decoder Questions
Is this VIN decoder free?
Yes. This page uses the free NHTSA VPIC VIN decoder API to return available vehicle details.
Can a VIN identify my exact tune?
A VIN can point you in the right direction, but the correct tune also depends on installed hardware, controller support, stock read data, fuel, tire size, gear ratio, and the full modification list.
Why is my engine or transmission blank?
NHTSA data depends on what was reported by the manufacturer. If a field is blank, confirm the detail with underhood labels, build codes, service information, or your stock read file.
Do I still need to upload my stock read?
Yes. The stock read is required for remote tuning because it contains the controller and calibration details JR Jones Racing needs to build the file correctly.
