deciphering parameters

[Perro903]

Good evening folks, so I've jumped off the deep end MMM2.0 stated, slowly been researching from various resources on reprogramming. question is mmm2.0 has good information but its for 871 mostly. how can i decode the parameters in a cm2350a? I'm assuming 2450s will be another ballgame since engineers are trying their dangest to keep people lost.

I comprehend all of it but there's some parameters I just can't seem to decode. yes, I know not all are meant to be changed but I would like to know what I'm reading, the comments help somewhat but not all. Next, most of the vehicles that come through here have already been deleted, I copy ecm data (for research purposes only) so I can compare to others to see what has been adjusted and how.

I did find one that had the turbospeed sensor turned off but I can't say anything about it cause wouldn't it make me sound like I'm up to no good? "Hey sir I copied your ecm data so I can play with it" most O/O first thought would be "what is he doing in my ecm!!!! he's screwing with my truck" How can I find what the original settings were before they were reprogrammed?.

when it comes to reprogramming it disgusts me I have to trust someone in a different timezone to "reprogram" it because if something goes wrong all they do is disconnect and wash their hands and they charge a buttload of money just to flash some kind of file they acquired from another source. Like I've read I do believe that each truck is different and each has to be programmed differently. all this is why I've jumped in head first into learning, so far I've had countless hours and many nights without sleep learning this stuff and still most times i feel lost.

I joined a mumbla session once but its hard to keep working and talk to the man himself, Rawze. whatever literature i can find i put on acrobate and let it read it to me, hate the part when they read all the symbols dash dash dash dash dash.... lol. well, sorry started off as a question post ended up being a rant. CARRY ON!!

The ONLY place your gonna learn the things you mentioned is on Rawze's mumble server.

(Metaphorically)...
- Last I checked, even the most talented machinists, engine builders, carpenters, repair techs, and even doctors, had to learn a lot of their trade from others plus doing professional training classes of some sort.

-- And NOT by tearing up everything they touch, only to have to guess at what everything was after the fact, no guidance or proper learning and analysis processes whatsoever.

Imagine going to the hospital/doctor to get a life saving operation after a vehicle crash only to find out the doctor about to cut you open, 'did not go to any kind of school, ever' .. and has only copied off others, doctor beating their brains out by themselves mostly to 'figure it all out as they go', not even knowing the names of half the organs inside you, or what they are for, ... trying to convince themselves 'it ain't that complicated' etc.. , as he is standing over you with that scalpel?????!!?>.

- How would you suddenly feel?.

- And when you ask them later on about why half your vital organs are cut up, missing, and why you are required to have a dialysis-machine for the rest of your life, when it was supposed to only be a hip replacement, ... they get mad at you and say 'they been doing it like this for 10+ years!!!..''' with that arrogant false sense of self confidence.. as you are withering away and dying by the day.

10 doctors later,.. and you come across the ONE GUY who explains everything properly, and shows you everything and every mistake the last 9 doctors have done in there, and now you see all the damage for yourself. It makes your blood boil over because the last 9 people you have seen after having nothing but repeated suffering.. and all that wasted time and moneys, all because... THAT FIRST DOCTOR WAS TOO LAZY OR PROUD TO TAKE PROPER TRAINING, CONVINCING HIMSELF THAT THERE IS A SHORTER WAY TO LEARN IT!!! .. then none of this permanent damage, and chasing your tail for years with failure after failure would have ever taken place the first time.


- That is about how most truck owners feel after finding out how bad their delete programming really is, and how big of a plague it is in our trucking industry.

Unless you go over to mumble and start learning this stuffs correctly, you're essentially wasting your time completely. It will take you 10x to 20 x times longer to learn it on your own, and for no reason at all. Most people do not spend more than a few weeks learning via mumble, and going on to creating their own solutions... where EVERYTHING is understood, and not just a bunch of mindless guessing. Copying stuffs out of people's engines and comparing it all is pointless and mindless,.. and makes for a lot of assumptions and bad habits. It only makes for bigger and bigger messes.

What you're trying to learn all on your own, and are beating your brains out so hard about, is exactly why the mumble server exists. The more you try to do stuffs on your own, and without professional guidance... the harder and more waste of time that you will end up at. You even say it yourself in your own post up there.. 'beating your brains out'... and 'cant figure out why' /.... because there is NO GUESSING, and NO ASSUMING of absolutely ANYTHING in there when someone learns to do things right.

(Another Metaphor)...
It's like trying to build the latest, fastest PC out there, spending $10k+ on all the individual parts, and everything arrives in a box all jumbled up. And then instead of taking the extra 10 minutes to stop and read the manual(s) as you go along with your first build, so that you don't blow anything up, you decide to run off to the local butcher-shop PC store, and look inside all the butchered up PC's there (of which are not even build right most of the time), because you're too stubborn or proud to simply OPEN THE DAMN MOTHERBOARD MANUAL THAT IS RIGHT IN FRONT OF YOU AT YOUR FINGERTIPS, SIMPLY BECAUSE YOU HAVE TO FOLLOW ALONG, AND TAKE THE TIME TO LEARN IT AS YOU GO instead?.

Doing things with a blind mans approach ALWAYS costs 10x the efforts in the end with 10x the issues, false assumptions, 10x the mis-understandings, and 10x poorer results.

- Now how ridiculous does that really sound when looking at it from the outside, watching someone else struggle, when the correct info, methods, etc. literally right in front of you all along?...because that is what you are essentially doing according to your first post.


Also, if your 'mm' document does not say 2021 at the top, then it is not likely a full version and is missing a lot of content pertaining to newer engines too. Hanging out over on mumble, you would have found this out fairly quickly.

These ecm's are dumber than a brick, and fairly easy to comprehend once the programming is broken down and arranged properly. NO engine software can do this. Not CT, not winols, efi, ezlink, hptuners, .. NONE OF THEM!.


THAT SEEMS TO BE THE PART THAT YOU ARE MISSING THE MOST!!!.. YOU ARE NOT LOOKING AT ANY OF IT PROPERLY!!!... AND THEN GUESSING AT EVERYTHING!!!.


Your struggle otherwise, is like learning how to be a mechanic all on your own, ... and the last guy who they fired, that you replaced ... in a rage, has dumped over the master tool-box set and work tables, all into the floor,.. and now all the sockets, socket-sets, wrenches, wrench-sets, screwdrivers sets, hammers, extensions, specialty-tools, fittings, spacers, and engine parts for the engine he was taking apart, ..... LITERALLY EVERYTHING, 35,000+ metal pieces of every set, is now jumbled and piled 4-feet high in the floor.


Are you going to try to put that enigne back together.. WITHOUT CLEANING UP THE HUGE MESS!!???>>... or are you going to dig and prod inside that pile of utter mess .. EVERY TIME you need the next socket.. or wrench,.. or maybe after 3 hours of digging .. maybe you find a specialty tool that you need to put something together properly ... all because no one bothered to take the extra 20 minutes picking everything up and organizing it TO SEE WHAT THE H#ELL TOOLS THEY HAD, AND WHAT THEY HAD TO WORK WITH BEFORE STARTING !!>,>>>

And then 5 days later, something goes very wrong on startup,.. and after even more hours of pointless digging,.. you find in that giant pile of stuffs,, some bolts that belonged down in the middle of that engine somewhere ... and now you have to tear the whole thing down again, starting all over, just because someone did not bother to do things right, by fully organizing their environment to begin with.


--<>>> your posts are literally describing this same type of frustrating situation for yourself.


There are proper ways to look at this stuffs. You will not find them in a manual or in any engine tuning software somewhere. Someone has to 'Train you' on how to do things properly,.. and it takes dedicating and motivating yourself full-on and not some spotty garbage and listening to 'e-books' type documents to do so. You can read as many e-books and pdf's into your eye and ear holes as you want to about how to ride a bicycle,.. but ONLY GETTING ON IT, AND ACTUALLY RIDING IT, TRAINING YOUR COORDINATION EVERY DAY OR SO, TAKING THE TIME TO GET BETTER AS YOU DO SO, actually TEACHES YOU HOW TO RIDE.

- And no,.. not really ... There is nothing in the newest CM2450's that is a 'Mystery' in them at all. All they have done is added a few more features that make sense, given the context and advances in engine technology.

yes sir Mr Rawze I understand your point totally and your metaphors hit right on point. What times are you on mumble? I will do what I have to to be there on those times

Unless I have been pulled away for some reason (local shop wants me to look at something, yard work during day on occasion, etc.) ... I am usually always on there in the afternoons and evenings thru til about midnight (EST) most days. I am on mumble most of the time otherwise.
