    Validation checksum failed. You will be unable to save or flash this file.

    This isn't a bug in the software, and is perfectly normal.

    When you read your PCM and then try to open the file with VCM Editor and receive this message here's what you should do:

    1. Submit a ticket to support by filling out the form at support.hptuners.com. Make sure to attach the tune file (.HPT file) to the ticket when submitting.
    2. We will review the file for integrety and if the checksums are correct & not disabled, missing or corrupt we will send you an update as soon as possible to fix this issue.
    3. The fix will be included in all future shipped software and updates.

    Fixing these issues are #1 when it comes to support so you can be assured that you have our full attention when we receive one of these emails.

    Thanks for your understanding and patience (we know what it is like to get something new only to have to wait to use it).




    x7F Negative Response Code received when attempting to write

    Nissan/Infiniti vehicles can be very sensitive to battery voltage and battery load when you attempt to write a module. Make sure that that the battery load isn't too high by turning off various electronics (such as headlights, radio, A/C, etc.) and try to write the vehicle again.

    If you still receive this error after turning off all various electronics, please open a support ticket by filling out the form at support.hptuners.com
