    E38 - Cooling Fan Desired % vs. ECT - Table Column Axis Edit Possible?

    I would like to make the cooling fans come on earlier. Am I missing something? I can't figure out how to change the settings to make the fans come on at say 180 degF. Right now the table column axis starts at 192.2 degF. Thanks in advance for the help.

    Look in the sticky section. There is a write up on this topic. Short answer is you can't go lower than the lowest setting in your table without changing your OS.

    Ok. Thank you both. So I just read that sticky. Just so I'm clear, if I convert to the 2 bar OS upgrade, all I need to do is change my Map Sensor Linear and Map Sensor Offset back to what they are now and then I can control the fans to a lower setting without messing anything else up? Is there any downside to doing this?

    Looks like I also need to populate the VE tables. Those appear to have to be rescaled of course. Anything else that I am missing?

    Here is the updated version.

    Don't put more than a 15 value in the first temp cell and then of course fix all of the other stuff you mentioned including scaling the VE table for your setup. You might also want to look into pedal for PE and your MAF table unless your spraying meth or something like that.
