    01 tahoe efan conversion

    Hey guys i know this thread has probably been done over and over again. But i need help. Im converting my 01 5.3 tahoe to efan using factory fans from an 05, nelson performance 1pin #42 wiring kit and of course going to tune with the hptuner. It will also hook up to ac clutch wire. so my question is does anyone or is there anyone willing to help me out on what settings for the tune. fan on off fields etc.

    That's no problem. Just copy the settings from a 2005-06 model Silverado that is already equipped with e-fans.

    They use a different type of A/C system though, so those settings related will be different (high/low pressure) and they also use two outputs, where his will only use fan-low and then high fan is run off the a/c clutch...

    OP post your file.
