In the NFE Toolbox software, go to the
Profiles tab and change the
Preheat Type to
Curve. Click on the
Edit button (next to
Preheat Curve). The Power Curve Editor window will appear. You can edit the power curve to your liking, give it a name of your choosing, and save. You can create up to 8 curves per profile. (You can also reach the power curves via the Advanced tab.)
Finally, after the new settings have been successfully uploaded into the mod by clicking on the
Upload settings button, you will also be able to select your desired preheat on the mod itself so the NFE Toolbox software and USB connection only are needed to Upload settings.
