Popping Under acceleration

[Rawze]

The program was sent to me for this truck.

Here is what is seen at a glance... this is an attempt any ways, for a de-mandated engine according to the engine file ...

== (issue)> Aftertrearment systems have not been shut off properly. It is so incomplete that it would not surprise if it went into a derate of some sort. That, or maybe derate(s) or other ghost issues that come and go.

== (issue)> Someone has destroyed some of the tables needed for proper intake and charge flow for the engine/vehicle. This is not good, and has nothing to do with any de-manade, power, or other reason for someone to do this. - It is simply a clear sign of someone not knowing what the heck they were doing in there.

== (issue)> Some of the auxiliary emissions systems settings have been set improperly. This can make engine sometimes not run quite right, like a ghost that comes and goes depending on external factors.

== (issue)> The turbo re-mappingg seems to be too low for a Volvo truck. it also is likely that it is not spinning fast enough to make positive pressure at idle. This can lead to the turbo bleeding oil into the CAC, possible idle issues, etc.

== (issue)> The fuel pressure maps have been edited and are set a bit wonky. It looks like someone maybe copy-paste edited them incorrectly. They are also set to harmful levels al lower fueling rates.

==Lastly, the base engine file that was used is 8+ years out of date. The ecm needs a software update before the file can be repaired.

The program overall seems to be a bunch of copied settings, blind guessing, and a whole lot of not knowing what someone was actually doing, but likely not realizing it. It is a fine example of how bad delete files get made, and how engines get damaged as a result. This one is not completely harmful, just ... well.. not right, and very unstable... which can lead to harm in the end.
