Dumb fan question - Third Generation F-Body Message Boards

Hello guy's. I have an 88 IROC with a 383 TPI. I have a 165 ECM and am using the 6E mask. I am running a 180 degree thermostat and need my fans to come on earlier than stock. I have 2 cooling fans and have removed the A/C. I am using tuner pro rt and found the constant for fans. However my choices are fan 1 on temp with A/C on, fan 1 off temp with A/C on, fan 1 on temp with A/C off and fan 1 off temp with A/C off. How do I set the fans to come on earlier? Is there a seperate comand for fan 2? Thanks.

I found the fan 1 on and off settings and changed them to about 189 degrees, and my SD system works great.
The settings are in celcius, so you will have to convert your settings.
Fan 2, from my experience runs off a sender in the head. You can get them in several settings.
Just my humble opinion.
