How To Use This File
Read and save your vehicle's original file using supported HP Tuners hardware and VCM Scanner/Editor software.
Open your original file and this purchased file in HP Tuners VCM Editor.
Use Compare to review the differences table by table. Confirm that each change applies to your controller, operating system and build.
Copy only the appropriate calibration changes into your own original file. Do not copy VIN, serial, security, segment or unrelated vehicle data.
Save as a new file, flash safely and datalog. Verify fuel trims, commanded fueling, spark, airflow, idle, transmission behavior and diagnostic operation before higher-load testing.
Before You Purchase
- Confirm the year range, engine, controller and calibration type match your application
- Confirm your operating system and available tables are compatible
- Know all engine, fuel system, transmission and drivetrain modifications
- Have the correct injector and sensor data when those parts differ from the source file
- Understand how to compare, copy, flash and datalog with HP Tuners
Not Included
- Custom remote tuning or VIN-specific revisions
- HP Tuners interface, credits or vehicle licensing
- Installation, mechanical repair or diagnostic labor
- Guaranteed compatibility with every operating system or hardware combination
- Automatic correction for different injectors, sensors, fuel, gearing or modifications
Compatibility Warning
Camshaft name alone does not guarantee compatibility. Engine size, injectors, MAF, MAP, throttle body, transmission, gearing, fuel type, operating system and other modifications must be checked before copying changes.
Compare every section before copying. A calibration from another vehicle may contain different segment data, airflow models, injector information, transmission settings, diagnostic settings or hardware assumptions.
Do Not Blind-Flash This File
Writing an unmatched file directly to a controller can cause a no-start condition, poor drivability, incorrect fueling, transmission problems, diagnostic issues or controller recovery problems. Always build the final calibration from your vehicle's own original read unless the file has been specifically verified as a direct match.
Digital Product Notice
This is a downloadable digital calibration file. Because compatibility depends on the customer's vehicle, controller, operating system, hardware and modifications, the buyer is responsible for confirming suitability before use. Performance calibration should only be completed by someone who understands HP Tuners and can safely verify the result through proper datalogging.
