Cm871 ecm tuning
I need a good tune for my isx cm871 it a 525 hp 1850 torque engine. I bought that engine from a crashed 2009 kenworth did a complete overhaul on it in my driveway and put it in my 2002 freightliner Columbia. The issue I am having I used the cm570 ecm that my pervious engine used but that he was set too 500 hp 1650 torque. The engine ran fine until recently that ecm died it was the original ecm to the truck too so I don't feel bad. I have rewired the harness back to cm871 however my truck didn't have all the mandated stuff on it so I need to tune the cm871 to ran properly with the vgt turbo without having to add all the stuff on the engine

maybe this helps...
Quote: If ya really want that type of thing done then your actually far better off doing it for yourself if ya know how to use a laptop and have a datalink adapter that can be had off flea-bay for about $300 bucks or so.

That way your not at the mercy of some di$ckhead who ripped you off for a few thousand$$ and then ...

A) - you end up right back on my forum here in a year or 2 anyways, just like all the other bad deletes we seen here every year, but this time, your now starring at a blown head and crying to me, asking how to copy the garbage-can delete program out of your ecm so that I can tell you what went wrong.

..or...

B)- You are now at their mercy completely if your "custom program" ever gets lost or the ecm ever has to be replaced.. because they are now holding your truck hostage and asking for many thousands of $$ all over to flash or program it again due to you not thinking past the immediate future, which is quite frankly a set of bad choices as a truck owner.


- That is where your headed real fast by blindly assuming there are actually competent shops all across the country that can do that type of thing.. because they don't exist!!!.


your choices are...

(Best choice)...
If you are not a complete dummy with a computer (you know what a start menu is and can navigate your way around a spread-sheet, copy files, use e-mail, etc.), is to do the job yourself. it really is not hard to do and get right. Here is more detail on this ... of course, assuming that your truck does not have a bad delete in it already and is still factory programmed, so 'step-2' and 'step 3' in the post referenced below would not be necessary...

- You now have something 100% correct, it cost you nothing but maybe a few hours of your time to walk yourself thru it, and also you now have the proper tools and files necessary to replace the ecm and have a copy of the program so that no one can hold your trucking business hostage if u ever need it again in the future. After that, it is simply a matter of dealing with hollowing all the cans out 100% to the bare metal (or straight piping it), putting in a maintenance-free crank case filter, and installing a block-plate of decent quality. Many people do this for themselves as well.

Doing the programming yourself (and dealing with any hardware if necessary) would be the first choice.

...

Second option is to not deal with any of the programming part yourself and instead, get with forum members 'running rough' or 'RollinCoal' or possibly 'Mr. Hag' if u need help with it or want something done remotely.

I don't need to hollow out any filters or installed any block of plates all I need is a good cm871 tune without any of the mandated stuff
