This above, leads to this next post...


What am I actually looking for when I review other people's programs to determine if they are harmful or not.


* I am looking @ phase01 settings to see if the ecm is going to get stuck in one of its emissions warm-up modes, trying to perpetually heat that DPF, src, etc. cans up to no avail because no one bothered to edit the engine operating mode control logic to prevent it. -= This is one of the most harmful things to the engine overall, and the biggest, most overlooked mistake that bad delete programs have in them.. all while the truck owner swears it runs smooth.. as it eats the liners out of the block, over-spools the turbo, and causes progressive damage over time.

* I am looking at phase02 settings to see if someone shut off sensors and hardware like the egr valve, doser injector, nox sensors, etc. or if they simply ignored shutting these things off properly, and instead, just blocked all the fault codes from showing up in the dash. when they only use blocked faults, this makes the ecm unstable and it also makes it difficult for someone to troubleshoot issues in the future. Mysterious power loss after a while, or issues with the power/boost, or fuel efficiency that cannot be explained all of the sudden .. problems that are elusive ghosts because faults are not allowed to show up in the dash or to be displayed and the ecm cannot tell you what is wrong any more. -= This is not very good.. though often I do not consider this a "bad delete" just because the blocked faults in itself... i just consider it tacky, and bad practice, and it can give someone a lot of grief if many blocked codes are used instead of shutting things off properly.

* I just glance over the derates and shutdowns that other people do.. most of them will not make the engine unsafe to operate unless they shut off the oil pressure shutdown or the coolant over-temp. This is all a matter pf someone's personal preference, so I do not normally call a delete bad if someone does different things here. i do however think that the truck owner should be made aware of what will and will not shut the engine off if something goes sideways though (like coolant or oil loss etc).

* phase04 - I look to see how complete someone did this part. if a lot of setting were missed here, then the ecm at some point in the future can suddenly act differently with no explanation.. leaving everyone guessing as to what might be wrong. -= I have seen trucks sometimes go a couple years, then all of the sudden a mysterious shut down or derate. No faults, no codes, nothing.. because an emissions manager finally decided it has enough, it was not fully switched off. Causes a lot of grief and ghost issues sometimes and that is not good.

* phase05 - I look to see if ALL egr gas requests for the combustion process have been switched off. I look to see how thoroughly someone shut off the egr managers, etc. - Not doing things properly here can lead to improper combustion and harm to the engine over time. I am not looking for someone blocking a fault code for the egr valve so much, though it should not be necessary, ... but rather egr gas assumption corrections and the like so that the combustion manager does not get offset and output the wrong data for turbo, fuel-air-mix, injection timing, etc.

* phase06 - Shutting off Aux. emissions systems properly is very important. It contributes heavily to instability within the engine as a whole. The aux emissions will screw with everything directly like injection timing, fuel-air-mix, power, torque, fueling, .. all the important stuffs.. and ironically .. it is NOT trying to protect the engine, there is not logic inside it for that, .. but mostly just clamp emissions output and it often does so in harmful ways. bad, unpredictable injection timing, other unstable offsets, etc. is the result. -= Those system have to be dealt with properly or someone ends up with a shortened engine life, and that is not good. it will fight tooth and nail against a lot of other changes inside the ecm and make the engine have less than optimal, have mystery losses of power levels, torque, smoothness sometimes, etc.

* pahse07 - (repairing the combustion processes) This is the second biggest concern, right along with engine mode control (phase01) one of them all. Most people doing engine "tuning" have no idea how to do these things and cause a lot of harm here. I have seen all kinds of crazy thing that people do here... and ironically, leaving all the combustion, etc. to the factory defaults (untouched values) is one of the bigger crimes that shorten engine life.

There is no fix-it sauce here ... The factory setting all on heir own, once the emissions system have been removed.. IS EXTREMELY HARMFUL!. Yet most people that go digging inside these delete files have false assumptions that the "factory or alpha1 settings' are somehow going to be ok, or less harmful if they are not touched. This is very bad, and is just as common as not editing engine operating mode states properly.

To add insult to injury here.. many people will go ahead and edit this stuffs ..but edit it the wrong direction, use settings from other engines that are NOT compatible, and do all sorts of horrible things that make matters much worse to boot. I see this a lot too.

* phase08 - I usually laugh or get a giggle out of this. I see where these "custom tuning" people will try to change the HP or torque settings, and then do not deal with any performance limiters, they set big HP and leave the dam$mned load based speed control and smart torque, etc. on and then wonder why it still feels soft when accelerating. That or they go way over-board and try to make ridiculous numbers for the power/torque. the ecm fighting them the whole time because no one bother to shut off any of those performance limiters and things that are going to absolutely fight against it. -=This clearly shows that people in there doing these deletes programs really do not know what they are looking at most of the time.

That is the bulk of what i look at when reviewing someones delete file that they send me. -= Unfortunately, it paints a very clear picture of how short-sighted most of the people doing this type of work really are.. and yet most of them have somehow convinced themselves that they know what they are doing. -= It is truly sad, it is beyond a complete joke, and if you even try to mention some of this stuffs, and how to do it properly to them, or how the ecm actually works internally, they only argue with you, fight against their own arrogance, and deny everything you say.

For this, I say .. the more that people can learn this stuffs for themselves instead of using these arrogant, ignorant fools who are quick to shove a questionable file into your truck with only a couple hundred changes and some destructive offsets.. .. .. the better off the trucking community will be for it by staying away from clowns like this.
