Turbo Spooling up at Idle

I just compared the 2 calibrations.

EF10054.xx (what is supposed to be in his truck).
vs.
EF10045.xx (the one in there currently, is incorrect).

here is what I found...


* CAC settings are very different. - the truck will suffer fuel and other efficiency losses + contribute towards emissions issues. This will also cause the turbo to over-work itself and surge. This has nothing to do with the HP differences.


* Your truck has an intake air throttle. -- the program that was put in has it turned off / diasbled. - this is going to cause the intake throttle body to randomly close.. leading to the engine shutting down randomly with no warning, and may even make it not run at all at some point in its future.

* The SCR and DPF settings and can sizes are not compatible with the programming that was put in the engine. - This is going to make the truck suffer SCR and other emissions problems.


* The program you are supposed to have, since it is for a smaller SCR and DPF element, does not require the turbo to spool up and scream like hell after cranking the truck,.. in the EF10045 (wrong) program, the SCR element size is much bigger, and requires the turbo to choke the engine and warm it up rapidly for it to function properly. -- This is exactly why your turbo is now screaming its arsse off at idle, where it did not do this so much before. - This will also lead to a lot of other smaller issues down the road like turbo over-working itself, a lot of excess fuel consumption at idle, difficulty during the regen process, and exhaust running hotter than it should all the time.


-- All in all,.. SOMEONE SCREWED UP!!! --- THESE 2 PROGRAMS ARE NOT COMPATIBLE -- AND THIS IS A NICE EXAMPLE OF WHY A PERSON HAS TO ABSOLUTELY BE CAREFUL OF WHAT PROGRAM SOMEONE PUTS INTO THESE NEWER ENGINES!!!

Here is a why this is such an issue, and what people need to know about this kind of thing...

========================

The only proper way to place that engine/truck at 500+ HP, 1850 torque is to use the original program that goes in the truck, and change the power/torque settings in it directly (custom programming). there is no factory program that is comparable with that engine/truck on its own that will get it to those power levels.
