Electric Fan Patches

Purchasing one of our LS1, C6, or SPAL electric fan kits? You will need to have your PCM patched in order to operate them. The patch can be done by anyone with HPtuners tuning software. Start by visiting our fan patch link here to download the appropriate file. Compare your file to the downloaded file, copy the fan settings, and reflash.

Don’t have access to HPtuners software? No problem! With the purchase of our electric fan kit, we will patch your ECM for free (just cover return shipping). Please enclose a note in the box with your name, contact info, and which fan kit you bought and we will patch it for you. Electric fan patches are typically turned around the same or the very next day.
