If the psi/kPa values are higher than G0911 or G0918, then it will set those pins to ground, thus turning on the fans.
Sounds good Ill keep you posted!! Ill test it tonight!

No the engine missfire was something else... but its all good...it was a bad wire to a fuel injector...pulled it recrimped it...no more misfire.

The Fan problem happen with my stock PCM OS then i switch to this new PCM with the 6.0 /4L80e on it so it was easier to tun.... but the problem existed pre PCM swap

Ok, sorry your posts are all over the place, very confusing to read... so the efan problem started right after you melted the efan harness, correct? so it worked prior just not after the efan harness swap? no other changes were made inbetween?

Yes definitely... but the problem with my search results is that they arent the same issue. Here in this link you can see he is talking about air temps in the cabin... I have no issues with my air temps.. hot or cold.. they work
