The file is in my email right now though from the guy who did it.

I was sent the file this morning. Here is what i see at a glance...

** The engine ser# calls for program EF10044.xx and the program sent to me is EF10060.xx.
The 2 programs are NOT compatible. Different truck intake, cac, and exhaust settings, so there is some issues with engine efficiency, fuel mileage, etc. right off the bat. The wrong file for the engine and vehicle is in the ecm.


** This program lacks any necessary corrections to engine operating mode control logic. Many of these modes deal specifically with exhaust device (DOC/DPF/SCR element) heating, and they are all still active. With no editing of the engine mode control logic, the engine will continue to enter one or more of these operating modes resulting in the engine creating extra heat in the exhaust all the time by way of over-working the turbocharger and cylinders in attempts to warm up an emissions system that is no longer present. This is harmful to both the engine and the turbo, causing higher than normal friction all the time, significantly shortening engine life. It should be noted that this mistake/oversight is one of the most common (and most damaging) mistakes that is seen in bad delete programming.

** Many faults have been block from being able to show themselves. This shows a serious lack of someone shutting things of properly. Here is the list of faults...
fc2375, fc3166, fc2272, fc5426, fc4677, fc4572, fc3137

** ALL egr gas request logic and egr gas mix assumptions are still active, meaning the combustion process is going to assume all the egr gas is still there. Engine will run too lean and have terrible injection timing as a result. This is harmful and significantly shortens engine life on an ISX.

** All of the aux. emissions system are still set active. This is goign to make the engne weaker and run funny sometimes, it trying like h#$ell to meet an emissions standard that it can no longer satisfy. it is also harmful to the engine over time.

** They left the now, too-far advanced and harmful injection timing at the factory settings. Did someone think the ecm has some kind of unicorn fairy fart-dust inside it to make it fix itself?.. Sorry, but there is no automated fixit-sauce inside these ecm's?. they are dumb as a brick, and this thing will tear that engine up like this.

** Turbocharger has NOT been re-programmed at all to prevent it form over-spooling and over-boosting all the time due to the egr and other systems no longer active/blocked, holloweed out etc. - This thing is h#ell bent on destroying the turbo over and over like this.


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

setting aside the fact that it is the wrong program installed for your truck/engine ...

All in all, it is one of those garbage-can, fly-by-night, crappy, so-called "Factory deletes" where some complete moron thinks that the ecm has some kind of fairy dust inside it to fix itself when you only block all the fault codes off and do mostly nothing else. it is the lazy-man way to jail-break the ecm at the cost of the engine life, plain and simple... and then typically charge big $$$ for the crap too that took someone all of 5 minutes to shove into your ecm.

Welcome to the bad delete club!.
