Just found out that Quadzilla high idle and Cummins High Idle can co-exist with each other with no problems. This morning I fired up and it was 24*F outside no grid heaters hooked up started easily with about 2 extra revolutions of the engine. 30 seconds later the high idle fire up on the Quadzilla. Walk back in the house. 10 minutes later walked out anf jupm in the truck and looked at the Quadzilla and it was 150*F it should of cancelled. It did the power level was shown in RED and level 3 was selected it was the Cummins High Idle was running 6 cylinder mode. Cancelled normally with the press of the brake pedal and of and running. No issues... 

Just wait.   Been there done this.  Dont run them together it will cause issues.  It might just be 3 cyl mode, I dont know, but it will create a very unhappy situtation.

 

 

no something that should be recommended to people.

That I've not had happen but the 6 cyl on both no harm. I can see the blending of 3 cylinder and 6 cylinder being a problem. I'm going to shut off the Quadzilla this morning being its only 17*F.
