How to Load a Custom Tune Using the HP Tuners nGauge

Posted by Jonathan Baker on

Step 1. Save the Jonathan's Performance custom tune from your email to your computer.

Step 2. Connect to the HP Tuners nGauge with a mini USB cable if you have one, or unplug the OBD2 cable from the car and remove the SD card from the HP Tuners nGauge and install it into your computer using the SD card adapter. If using the mini USB cable, when the HP Tuners nGauge powers up, go to "SETTINGS>USB SD" for the HP Tuners nGauge to be recognized.

Step 3. Find the nGauge folder/SD card on your computer and open it. Find the folder "Custom Tune Files" and open it. Save the Jonathan's Performance custom tune file to the "Custom Tune Files" folder.

Step 4. Eject the SD card/nGauge from the computer, and re-install the SD card into your powered down HP Tuners nGauge if removed.

Step 5. Power up the HP Tuners nGauge

Step 6. From the main menu, select "TUNING>LOAD TUNE". Then select the tune you wish to load into your vehicle and click the Check Mark.
