Changing values in bin

Is there a place in the bin where I can change the temp at which my secondary fan comes on? I looked around in Tuner Pro and did not see anything. Am I missing it?

Not in the '746 ECM. Fan is controlled by the switch in the pass side head between 6 & 8.

Edit: noticed you mentioned secondary fan, this is the '87 TA? IIRC the answer is the same as the '746. It is not under ECM control.

Need to post which ECM/vehicle in order to get the best answer.

Thats one of the sucky things about most TBI ecm's. I wonder how hard it would be to make a patch that would incorporate the fan control into the ecm? That would be very cool. Man I need to get into source code.
