Why this page exists
The clean workflow: match, purchase, upload, flash, log, revise
The page and builder keep the product choice, customer responsibilities, and file-delivery path clear before checkout so support starts with the correct information.
After Purchase
Use the private Tune Portal for the stock read, order details, build information, files, feedback, and revisions.
During Flashing
Use stable battery voltage, current supported software, the correct licensing, and a reliable connection for reads and writes.

Remote tuning answers organized around the actual customer journey.
The questions below cover device requirements, stock reads, vehicle licensing, product types, Tune Portal delivery, datalogs, revisions, turnaround, mechanical readiness and downloadable files. They are written for a single owner-operated service: Jason personally builds the supported custom calibrations and customers communicate through one organized portal.
Before checkout
Know the year, make, model, engine, controller or OS when available, camshaft, fuel, transmission, converter/clutch, tire size, gear ratio and complete modification list. Confirm you have supported hardware and the required credits.
After checkout
Use the private portal link attached to the order. Upload the stock read and build details there, download the latest file there and return datalogs and feedback there so the complete revision history stays together.
Typical timing:Most first custom tunes are completed within 24 business hours Monday–Friday; busy periods may extend turnaround to 48 business hours.

Questions specific to this page.
Every structured answer below is also visible to customers. No hidden FAQ content is added for search engines.
What hardware do I need?
Use HP Tuners MPVI2, MPVI3 or MPVI4, or a specifically supported EFI Live device, plus the required vehicle licensing.
Are RTD and TDN devices supported?
No. They are not currently supported, though support may be added in the future.
Can I purchase an MPVI4 with my tune?
Yes. Select it at the bottom of the tune builder; vehicle credits remain separate.
What is a stock read?
It is the calibration read from the controller currently installed in your vehicle before J.R. Jones Racing LLC changes it.
Where do I send my stock read?
Upload it through the private Tune Portal attached to the order.
What vehicle information is required?
Year, make, model, VIN, engine, controller/OS when known, transmission, fuel, camshaft and every modification.
How fast is the first tune normally completed?
Most first custom tunes are completed within 24 business hours Monday–Friday; busy periods may take up to 48 business hours.
How do revisions work?
Flash the delivered file, follow the requested log/test procedure, upload the datalog and feedback, then download the newest revision from the portal.
What does Base Tune include?
Startup, idle and initial drivability with one revision, within the product’s supported scope.
What does Custom Remote Tune include?
A calibration built from your stock read with the datalog and revision workflow stated on the product.
Does a downloadable file include revisions?
No. It is an exact-match Compare and Copy reference.
Can I flash a complete file from another vehicle?
Do not do so merely because the engine looks similar. Compare the required tables and segments only when product instructions and compatibility support that workflow.
Are credits included with a tune?
Credits are separate unless explicitly stated.
Should I use a battery charger?
Use appropriate stable battery support during reads and flashes so voltage does not collapse.
Can tuning fix a mechanical misfire?
No. Diagnose and repair mechanical, ignition, fuel, wiring and sensor faults first.
What if I have a vacuum or exhaust leak?
Repair it before logging; leaks can distort airflow, oxygen-sensor data and drivability.
Do I need the exact cam card?
Yes, whenever possible. A stage or nickname is not a complete calibration specification.
What if my vehicle is missing from the builder?
Do not force another product. Contact Jason with the VIN, engine, controller and complete build details.
Where are tune files delivered?
Custom/Base files and revisions remain in the Tune Portal; instant digital products are delivered through Shopify’s order experience.
Who builds the custom tune?
J.R. Jones Racing LLC is owner-operated, and Jason Jones personally builds the supported custom calibrations.
