Changing temp in which the fans come on?

the fans come on when the thermoswitch sees 207°. Then it simply trips and grounds the circuit.
Unless you replace the thermoswitch to something with a different switching value, i doubt you can do it.
however, it's super easy to do with MS

To clarify, in the 1.6 cars the ECU does not control the fans insofar as responding to CLT temperature.
The thermoswitch that Brain refers to is the one mounted on the top of the thermostat housing. When it gets hot it closes a path to ground which energizes the primary fan relay.
The only thing that the stock 1.6 ECU does with regard to the fans is to turn them on when the A/C is active, and that is not a temperature-dependent activity.
