Correct! I was gonna put a fire truck ECM code in the truck (I’ve got fleet counts)but couldn’t find one ...

(just a general warning about those types of programs)...
FIRE TRUCK PROGRAMS ARE NOT WHAT I WAS REFERRING TO!!!!>... I SAID SIMILAR SHUTDOWN SETTING ONLY .,.. NOT THE WHOLE DAMN PROGRAM CHANGED OUT!!!.

NEVER EVER PUT A FIRETRUCK PROGRAM IN A COMMERCIAL ENGINE!!!/.. THOSE PROGRAMS ARE DESIGNED TO COMPLETELY ABUSE THE ENGINE AT ALL COSTS INCLUDING DUMPING IN FULL FUEL AND EATING THE ENGINE UP TO PIECES SO THAT A COLD FIRETRUCK FROM SITTING ALL NIGHT, ETC.. CAN GO BALLS TO THE WALLS ON A FIRE CALL.. EVEN AT THE EXPENSE OF THE ENGNE!!... THOSE PROGRAMS ARE DESTRUCTIVE OVER TIME!... AND FIRE TRUCK ENGINES LIVE A SHORT LIFE BECAUSE OF IT!.

I was taught in Cummins school that number need to match Case it’s based of engine internals ...

That 'cummins school training' is a curse, not a blessing. It is that complete garbage 'official training' crap that is the whole problem, and has been for years now.

(With regard to CPL)...
What those blind-man training manuals and idiot instructors don't tell you .. is that even within the same damn CPL programs ... (CPL=engine internals code, for those reading) ... is that many of those programs are NOT compatible with each other. .. You cannot put a damn program that was meant for a prostar/cascadia into a KW-W900 truck!> ... Even if the CPL numbers are the damn exact same!!!.

.. and that tiny bit of bulls#it data that Insite shows about the programs listed is just that.. Incoherent nonsense, .. and does not tell you ANYTHING WHATSOEVER on how compatible those programs might be with each other.

.. THERE IS A REASON that there are 300+ different programs just for one model/year engine.. and it is not because of internals!.

I CANNOT TELL YOU HOW MANY HUNDREDS OF ENGINES A YEAR THAT I SEE THAT HAVE THE WRONG DA$MN PROGRAM IN THEM.. JUST BECAUSE SOME COMPLETE IDIOT AT A STEALERS$#IT SOMEWHERE shoved the wrong da$mn program into a truck just because 'IT WAS THE SAME CPL' in attempts to maybe 'Up the HP/torque', or change some feature, etc... ONLY FOR IT TO CAUSE MAJOR ISSUES LATER ON for the truck owner...

BECAUSE THINGS LIKE ...

THE ENTIRE CHARGE AIR FLOW SYSTEM WAS TOTALLY INCOMPATIBLE with that make/model truck, and now its costing the guy $8,000 a year more in extra fuel due to mysterious mpg losses that no one can figure out, + slowly its eating the engine up.

A fine example of this is that Prostar vs. the kw-w900 comparison. That CAC in the prostar is only roughly only about 2 foot tall and sits ABOVE the radiator. - Its restrictive as all hj$ell, .. vs. that KW-W900 with its huge front end, and its 4.5 inch intake piping, and a CAC with ZERO restrictions, that is a big as the whole damn front of the truck. - You put that prostar program into that KW,.. and its turbo over-spool city. Put that KW program into that prostar, and it will have acdel issues and the turbo will always be lazy. Also you will get ghost fuel mileage losses on both trucks. - ALL because the CPL and other BS data in Insite shows the same.

THINGS LIKE having constant turbo issues.. because the program was meant for a DIFFERENT MODEL TURBO (such as heavy haul 36mm vs. fuel efficient 34mm models), and the thing is now over-spooling all the time, and its now eating turbos like candy.

THINGS LIKE the wrong aftertreatment modules in the program now vs. what is installed on the vehicle.. and now, its a constant battle of DPF and other issues.

.. the list goes on and on. -- THE ONLY WAY to tell if a program is actually compatible wiuth a specific make/model vehicle ... AND ITS ENGINE ... is to convert BOTH programs, 100% into plain damn English.. all 30,000+ adjustments, etc.. and and see what is actually different about them using professional tools meant for this.

Otherwise, your just pis$ing in the dark and likely creating issues for someone that might not even show up right away.,

Here is an article that I wrote about this in detail several years ago: I suggest that you read it carefully.

MY ADVICE for people in general who have had 'official training' and have suffered all the bulls#it brainwashing that those cummins schools training centers has done to them ... ... >> Is to STOP being the problem.. and learn to do things right instead.

IF YOU WANT TO KNOW how that engine actually works ... all the things that they don't want you to know... hang out here and you will learn it.
