CM871 code 2973

[Rawze]

Just about everyone who comes on this forum, all swears by their "reputable guy", almost always learns the hard way that their program has some sort of serious issues that may or may not show up right away. Most of the delete programs that people make, copy, steal off others, buy/sell, etc... then shove into other people's engines will shorten the hell out of the life it as well.

Pull a copy of the program out of the ecm and e-mail it to me for an inspection of safety and stability. -- AT LEAST eliminate the questionability of it if you actually value your engine and its longevity/stability.

I would begin by doing this first and foremost, because for all you know, it could be jumping operating modes unpredictably for some reason or another.

As far as programming is concerned,.. if it has been 3+ years since it was done, even if it has the best programming on the planet in it,.. It is well past due/ in dire need for some updates that have to do directly with power boost, etc. to correct some issues that are well known on the 871's.

ALSO, when is the last time you replaced the IMAP, exhaust gas pressure, and other important engine sensors?

What mods, things have been done to it mechanically?

Does the engine still have its factory VG turbo?

Has the crank case filter been drilled out? -- or are you using the cummins maint.free one?

Are the exhaust cans (DOC and DPF) 100% hollow? - Exhaust as open as possible? -- or something else?
