Manual Fan Switch Rover K

Hey everyone,

A known problem on the Elise with the Rover K engine is that the ecu turns the radiator fans on way too late at 105 C (221 F). Most people put a second cooling fan on the radiator and control it over a manual switch. I was now wondering if its possible to reprogram the ecu to turn the fans on at a lower temperature instead of making a manual control for one fan.
Ive currently installed a second fan on my radiator and was now just wondering if there is an alternative... Maybe somebody has done something similar in the past and could help with some pictures or directions on how they did it?
