I've already changed the tables back to what Russ has posted above.

But basically what I did was grabbed the first 2005 GTO stock tune in the repository list and copy/pasted all three fan tables over to mine:

Everything in 'General' section copied over
Fan desired vs ECT
State vs desired
Output control vs state

I didn't modify any of the cells, just copy/pasted everything into mine. Fan kicked on at ~220 and kept running all the way down to 175F without turning off. I'm using a Mark VIII fan so it cools down pretty quick. At least I know that part of the tables are working properly because it comes on wherever I set the temp to.

I'm getting ready to go on a week long wheeling trip with the Jeep, so I'll probably leave it as is. It'll just run constantly which shouldn't be a big deal. I do have an over ride switch for water crossings.
