Default fan temps

Is there anyone around houston (tomball area) that has a tuning program that can check to see if my fans are programmed to come on at the right temps?

I've got ls1 fans and a nelson harness to compliment them. I'm pretty sure it is hooked up correctly but my fans dont turn on the low speed. The one does come on high with the a/c clutch though.

They are not turned on from the factory you have to have them programed. The a/c is not computer controlled.

I have a tune. I asked to get the fans turned on (I'm not that clueless).

Blue pin 42 is the one you want. Make sure its pushed all the way in thats usually the problem.
