Default Tunercat Def File Problem

I just had Tunercat send me an updated version of their $EE definition file, and for some reason I can't find the fans on/off for coolant temperature in the ECM Constants tables. Any idea what I'm overlooking?

OK, I found it. It now has it's own table.

Hi,

I've been lurking around here for the last year or so and have finally got Datamaster figured out(Maybe). Can I use tunercat to just change the fan on and off temps?

As long as its an available option on your ECM. Tunerpro is cheaper though.
