You'll need to have some with HPT flash in the discrete fan settings or find someone who can create a CAX for you.

That's disappointing, but thanks.
I'd like to discuss this further. I have no less than 3 e38 ecms on my plate right now that are having fan issues. They come from a variety of vehicles. All of them seem to have the same issue, the fans won't come on based off ect (except for the vette file I posted earlier, it won't turn off). I can turn them on/off in the scanner software just fine but they won't come on due to temperature. They are all set to discrete and they are all in a swap vehicle. They set up to ground the fan relay trigger. I feel like there's more that can be done here. I know some e38s don't have problems, is there a way to see which are which? I'm assuming its based off OS. I looked into cax files some and I'm trying to learn, but I don't think I'm to the point where I'm comfortable getting that deep on my own.
What's easiest about the 2010 and up? Of the 4 I'm trying to straighten out 3 of them are 2010 or newer. The Vette setup that won't turn off is an 08.
The 2010 and up have the logic built into the calibration for discrete efans. I have an 08 Vette cal that has discrete set up. Send me your email and I
So you're saying that even though "discrete" is an option in a 2008 or 2009 e38 tune it won't work regardless???
If so, why is it even an option?
I can confirm that the GUI lets you think you can make the change but its not working.
I put down some hours of work trying to figure out why it did not work...until I found this thread :(
Really annoying and my car still still needs the adjustment.
If anyone can help me out let me know.
