2015 High Idle

I've read a few threads on here on the high idle mod but they all seem to be for the earlier generation 6.7's. My dealer said that the high idle on the new trucks is now fixed and works good. Is it true that they now come set from factory and will idle at a high enough RPM to properly burn fuel and not cause buildup on the valves? Thanks

It was never broke on earlier models,but its controlled by the outside temp. This is why alot of us did the mod. So we can high idle it whenever we want.

Nothing more that can be said here. I wired mine to AUX 3.

Q-180R4 is the only recent document I can locate on SEIC. I used a 12,000 Ohms resistor.
Really the only difficult part was finding the correct PCM wire with the hair thin color stripe.
