    Default Segment swap /fan issue for OS 12656198?

    Does anyone have a compatible segment for this OS? Or able to segment an OS in to get the fans to work? I can't get the fans to come on with temperature. I applied the patch and i can get them to activate with DVT, but they refuse to come on with engine temp. Doing a bunch of reading, i think that may be my issue. Here's my current tune file:

    Thanks!

    Are you retrofitting efans to a non-factory efan application? If so, there are tables you need outside of EFILive to accomplish this. The Fan Patch just rescales the ECT axis so you can control the start point lower, it doesnt update things necessary to control an efan.

    Yes I am. Donor vehicle had engine driven fans. How do I add the tables to get E-fans to work?

    I've tried that file, it doesn't start after I swap the "system" portion- even after removing VATS. I tried removing it before and after segment swap, for some reason it doesn't work.

    have you got the clutch pedal position sensor installed/wired to the ecu or have you tried turning off the clutch check?

    I have not. It's set to "yes" on my other tune, I didn't think much about it. I can try it. When I say it doesn't start, it will crank, but not fire.

    ah ok. so your wired to starter directly then. sounds like a vats issue. sometimes you need to play with the settings to get them going. just turning off vats doesnt always work. you might need to play with the vats type option.
