No these are not de-mandated. Completely stock what happens when you enable the temp stabilization parameter in the ECM it allows the DPF system to regen at a much lower speed versus your typical 45mph. It locks the DPF in a “keep warm” cycle (best way to describe it) till soot burn out is complete. So basically if you drop below 5mph it will kick the regen out and if you run a delivery truck or school school bus that does a lot of starting and stopping you can set your regen speed to 1mph and as long as the wheels are rolling you will continue to regen

Red engines can also be custom programmed to make everything a LOT more forgiving without doing a de-mandate. They also can be set to use a lot less DEF, etc... + disable all the derates and shutdowns so that it does not put you on the side of the road... similar to a fire truck. <- I thought that is what you meant, but your referring to something else.

Correct! I was gonna put a fire truck ECM code in the truck (I’ve got fleet counts)but couldn’t find one that the CPL matched on. Idk if there is a fire truck ECM code that will have the same CPL or not but I was taught in Cummins school that number need to match Casie it’s based of engine internals. Also you probably don’t use but a quick tip for not burning up fleet counts on insite once you re-cal the ECM and it gets to the end and you ECM calibrate successful box pops up do NOT hit finished on the calibration workspace. Hit crtl alt delete on your computer and enter your task manager and force close insite and you won’t lose any fleet count tokens. There around $110 a pop I’ve probably brought back several bricked ECMs with fleet counts and have been using the same fleet counts for almost 7 years lol


On another note I may request help on loosing the parameters on this ECM like a fire truck so it doesn’t derate. It’s the only wrecker we have. Although not used often our shop ain’t trying to pay a bill for a wrecker to come get another wrecker
