for the guys that are runing ls1 fans and the nelson harness, how are u setting up you program with hptuners. do u have it on "2 fans" or "aux fans"? and whats the difference between the two?

 

any one?

 

I don't know what the difference is, but Allen told me to set it to Aux Fans. This was after I had it set to 2-fans, and it still works fine so I don't think it makes much difference. I will switch it to Aux Fans as soon as I get my software.
