built04SS Posted March 30, 2014 Report Share Posted March 30, 2014 So I bought a Electric fan harness from ls1fans.com and have been having a lot of problems with this set up in my truck. I called one time to see if I could get some help and they said they would send me the tunning layout for the computer but I never got it and haven't been able to get a response from them in over a month... does ANYONE Have a pic of the setting I need to put into the computer? It's an 03 with factory electric 06 fans.. thanks Quote Link to comment Share on other sites More sharing options...

built04SS Posted April 5, 2014 Author Report Share Posted April 5, 2014 I'm using hp tuners Quote Link to comment Share on other sites More sharing options...
sprayed99 Posted April 5, 2014 Report Share Posted April 5, 2014 I'm using hp tuners This is an easy fix then. Go to the tune repository and pull a factory 05-06 truck file and look at the fan section for what the factory uses. I don't have my software in front of me to give you the info that I run on mine.

built04SS Posted April 5, 2014 Author Report Share Posted April 5, 2014 I'll see if i can do that... I'm to the point now where I want to just put a clutch fan back on it bc i have so many dang problems with it... it's burnt up 5 alternators bc of the huge amount of draw it's putting on the system, it always wants to run hot , to me it's just not worth it Quote Link to comment Share on other sites More sharing options...

It sounds like some funking stuff going on. Quote Link to comment Share on other sites More sharing options...

AKSSS Posted April 15, 2014 Report Share Posted April 15, 2014 My 03 originally had a 105 amp alternator on it. When the fans came on it definitely puts a heavy load on the electrical system. I ended up putting on a 160 amp alternator and problem solved. Then again I have a hpm harness and it has been flawless. If you can't find the fan settings I can get it for you tomorrow at work. Pm me if needed. Quote Link to comment Share on other sites More sharing options...
tayldss Posted April 16, 2014 Report Share Posted April 16, 2014 My efans would pop the fuses at first so had to swap them out for 40amps. Still notice a voltage drop every now and then when they kick in but my alternator isn't that old. I'm waiting for the day it dies then get a bigger alternator. Sorry i'm not any help with the tuning. I had mine tuned in at pcm4less. Quote Link to comment Share on other sites More sharing options...
zippy Posted April 16, 2014 Report Share Posted April 16, 2014 Send me your tune and I'll put them in for you. [email protected] I can understand being frustrated with the fan issue, but there are plenty of options to get it done. When you bought the harness from them was it with the agreement that they would supply the calibration info? Quote Link to comment Share on other sites More sharing options...
built04SS Posted April 20, 2014 Author Report Share Posted April 20, 2014 I put the bigger alternator on mine as well and and kept having problems then found out the harness had 2 bad relays in it so changed those now it half ass works.... truck still pulls alot of amps when they cut on and dims all my lights... and zippy I sent an email to them and he sent me an attachment that was empty and when I asked for it again about 4 months ago I never got anything even after I sent about 4 more emails.... and I'll try and send you the tune this week to that email Quote Link to comment Share on other sites More sharing options...
