Hey everyone. I put Dorman LS1 replacement fans on my 2002 Silverado with a Blackbear performance harness. The fans work through pin 42 on pcm and the green wire splices into the AC wire. My concern is that they never turn on HIGH if the AC is NOT on. Coolant temp gets up to 205 degrees at idle and in traffic. Is this just what I get with this or is there a way to turn them on high? I would like to keep temps down even with AC off.
I'll attach my tune but here's a layout of the settings.
2 Fans
Fan 1 On: 188
Fan 1 off: 184
enable speed: 0
disable speed :45
fan 2 on: 192
fan 2 off: 190
ac pressure on: 0
ac pressure off: 500
I've tried modifying these slightly, but they just won't turn on Full blast unless the AC is on. Thanks for any help! (NOTE: tune is in beta)
