E78 1.4L turbo - temperature and fans

Hello everyone,

I'd like to modify the engine map in terms of temperature settings. Specifically, I want to adjust the thermostat opening value and the fan activation temperature.

I found this thread: https://forum.hptuners.com/showthrea...wing-the-table

I have located the thermostat parameters. At which address should I look for the fan activation temperature?

I'm using a mappack for WinOLS for this ECU, but I can?t find a value that matches this mappack in my original engine map.

I am using TunerPro for editing. For reading and writing, I use KESS v5.017. Does KESS check the checksum when flashing the engine map?

Thank you for any help. I hope this post will be useful for others who want to tackle high engine temperatures.

Best regards.
