U7146 v.9r05 questions, 99 SVT Cobra

[BrutalMetal]

Just got the tuner and would appreciate some info..
Am I correct that this revision removed the ability to shut off the rear O2's?
My main question concerns the Fan settings, I'm in south Florida and want to lower the Temp when it turns on. My tuner has 5 different columns

1. High speed ECT1 on
2. High speed ECT2 on
3. High speed ECT off
4. Low speed ECT off
5. Low speed ECT on

What numbers should I input into these 5 choices?

I have the 93 octane tune loaded that came with the unit with 1.5 degrees advance timing at both rpm settings and it's pulling nicely.
I only have 700 miles on the motor ( Normally aspirated,forged internals, bored .20 over) and it's getting ready for a dyno tune but I want to do a little datalogging..
What is a safe timing degree I should look for at the 2-4K and 4-7K levels?
And what Air fuel ratio would be ideal? Thank you much, let's have a Great 2009, CJ

You cannot disable rear O2s, that requires custom tuning.

For the fans, simply make the same change to all fan parameters.

If you want them to come on sooner than how we set them, simply lower all values by either 5° or 10°.
