If you have HPtuners, you can just download your program from your truck, open it up, go to the fan controls, change the fan control from what you have to PWM if you use the corvette fans, or to the other choice if you are using LS1 fans. You can go to the tune repository and look at a stock corvette tune, and copy the fan on-off and AC settings from there. You can then change to fit your requirements from that. Looking at the stock C5 vette fan control setup really does get you close to what you want.
