I experienced for the first time the high temps that are attainable by our cars when left idleing or crawling along as I was for a given period of time. :eek2: So I was pondering which way I want to go to fix this "engineering flaw". Should I do the extra wiring & modules for the fan control that are offered by our vendors or buy a Predator programmer & change it with that? Unless I'm mistaken you can change the fan settings with the programmer right? If so, exactly what are those settings, 200,205? 200-205 I'm thinking is where I would like to be for the fan on/off. I would also change to a 180 t-stat to cool things off while driving at speed. I know a lot of you guys have made these changes & was courious to which way is the best to accomplish this. Also does anyone know what the settings are for the fan control wiring harness/modules sold by corvette garage among others?
