Hey guys, wondering if I am missing something here. Just did a tune on a 69 Camaro with an LS3 everything is working great minus the fans. They are coming on with key on. I set them to PWM and simply get relay chatter, so I know they are wired right. Am I missing something in the tune or is there an issue with the calibration? Also threw in another tune with the same OS and the fans worked fine on discreet. Any ideas from the experts?
