Ecm has full delete no egr,def , my issue is trying to make that newer motor to communicate with the dash


Your issue is to also to have the program checked in that ecm to ensure it is not going to tear up that engine too... pull a copy of it out of the ecm and e-mail it to me for inspection.


Does the truck use J1939 for the dash communications? or J1708? This may be a good place to start.
If you can contact me @ 972-369-6837 Jimmy, if it goes to voicemail leave message thanks

you are aware that the DPF and DOC , etc are required to make that thing legal... the emissions requirements follows the engine not the truck. - If all that stuff was not put onto he truck, One inspection at a scalehouse by the EPA police, carb, maybe even a state trooper ion some states... and your toast@>

Then there is the matter of a proper program if you did not install the DPF, etc... .. 90% of all CM871 delete programs will kill the engine. - If it was not done by one of the top 3 forum members on here, then you'de best be pulling that ecm file and e-mailing to me for inspection to ensure it is not harmful if you value your engine.

just thought you should know the can of worms you have opened there and its legalities. Actually I am surprised you had a shop help you do that so willingly. They are just as liable for doing the work.
How do I email you or contact you?

just talked to him on the phone...

His mess is bigger than he realized. Not only does he have a wiring problem .. I told him to go to quickserv and compare wiring on OEM side of ecm from 870 to 871... maybe that gets him along a bit on that end ... but the 871 he put in it has been butchered to hell and beyond.

He put a horribly deleted 871 engine in it that was inframed 70k miles before he purchased it that has the egr cooler missing, block plates for it, turbo is aftermarket vixed-vane garbage, ... the whiole bad-delete nightmere scenario .. how much money you want to bet that it was inframed because it blew up due to the butchering it had on it? .. inframe quality is unknown too .. What is the liner height set to? was it even counter-bored? -- was a brand new head used or garbage that was remanned from a shop,.. or china-knockoff? Was it all OEM parts? or aftermarket junk overhaul kits?... -- etc.etc.etc... sight unseen basically. So he purchased and had installed this nightmare of a butchered up 871 tier-3 (550hp) engine to replace a tier-2 870 (450hp) that he simply could have inframed and avoided these problems. He also said the truck has bee down for 3 months over this now too.

-- What a mess!.

* rip all the parts off the 870 and put them all onto the block and head of the now installed 871 ... or fix the OEM side wiring of the 871 and then proceed to spend another $8000 or more to put the engine (the 871) back the way it is supposed to be and pray like all he#ll that the inframe was half decent and it will hold up (but this is doubtful at this point).

Those seem to be his choices. Personally, I would rip out the 871 and tell the mechanic you are not paying for a half-baked, butchered engine, put the 870 back in it and inframe for a million miles w all the recommended things like talked about on the forum here and make the original engine right again ... but that is just me. It just seems at this point that any way he tries to get out of this nightmare, it is going to cost him a lot ore grief and moneys if he wants something reliable. The irony is that they were trying to "save him money" but instead only created nothing but a ton of grief for the guy.

The second option is for sure the only route to go if he plans on using it. The 870 is out and can be overhauled easily. Tell the asshat that sold him on that business sinking butchered 871 that he's not paying for it and get it out. At least then he's only out the time spent to pull an engine out of the truck. When its done he'll have a reliable "can sleep good at night" over hauled cm870 to make $$ with for the next million.
