Cold start idle??

[Rawze]

you can keep denying it like a fool, but unless you have your "buddies" programming checked out by myself or unilevers, you will always question what might be in your ECM.

Don't become another victim of a bad delete program like 90% of the rest of the guys who have that kind of stuff done.... you ABSOLUTELY NEED TO KNOW WITHOUT QUESTION OR DOUBT WHAT PROGRAMMING IS IN YOUR ECM ON THAT $36,000 ENGINE!!!!!

For all you know, it could be jumping in and out of several different warm-up operating modes because it is confused. Ask your "buddy" what operating mode(s) it should be in during cold idle, warmup, and then what engine operating mode(s) it should be running in after it is fully warmed up during various driving conditions. - There are 11 different engine operating modes inside that engine and each have a specific function. Modes like city, highway, cold climate, 2 different high altitude modes, thermal management modes, scr warmup modes, passive and parked regen modes, etc... A proper de-mandate requires a re-programming of the operating mode vectoring system in the engine to prevent it from jumping into operating modes that are no longer active. EVERY SINGLE BAD DELETE I have seen, no one bothers to do this and the ECM becomes unstable in its operating modes. Those idiots somehow think that magic fairy dust is sprinkled onto the computer and it will somehow magically figure out what to do after they have butchered all the emissions settings and it simply is not true. The ECM jumps into and out of those modes and is nothing but confused, making it to strange things.

Many of the bad deletes out there get stuck in scr warmup mode and jump in/out of it and make for an unstable engine operation because the hack-job delete is incomplete.


If he can't name them off the top of his head, he should not be doing deletes... and your engine is in trouble!!!.
