Hello HP Tuners Community,

I?m working on tuning a 2009 Nissan G37 (SH7059 ECU) and I?m specifically looking to adjust the fan control tables, particularly the thresholds for the high-speed fan activation and deactivation temperatures.

However, I am having trouble locating the specific fan control tables in the software for this ECU. Can anyone share or point me to the proper XDF or HPT definition files that would allow me to modify the fan control settings, such as:

1. The high-speed fan activation temperature.


2. The high-speed fan deactivation temperature.


3. Any other related fan control parameters for this vehicle.



If anyone has experience with this specific ECU or has already created a definition file for these tables, I would greatly appreciate it if you could share the file or guide me on how to access or modify these parameters.

Thanks in advance for your help!
