I sent you an email that should help you in regards to Insite and the Inline reader, along with some other stuff.
If you do not have a Cummins Quickserve account, you need to go to Cummins Quickserve and sign both of your motors up with the Engine Identification Number. Your 871, call the dealer and get the EIN from the original motor. The Quickserve account is free, and gives you access to everything you need to work on these motors, from parts to procedures and diagnostics. Here is the link: https://quickserve.cummins.com/info/index.html
Here is the Inline reader kit we pretty much all use here... You will need this, just buy it. https://www.ebay.com/itm/Cummins-INLINE-...SwIJlZ9U~7
Rawze is correct regarding power, the gear ratio in these newer trucks is rarely suited to the application the truck is intended to perform. And of course the first place everyone goes is the motor. That should be the last place other than say overheads and EGR tuneups.
And you do know about the fuel pumps on the 2250 and newer motors? That would be my first priority on that particular motor.
I do not know where you are located, but Mr Hag is in GA, just south of Atlanta in Griffin, Haggai Automotive and Diesel, look him up. He is the one trusted shop that most of us use if the need arrises.
My advice, purchase the reader I linked to above, and get copies of the ECM files to Rawze so that he can inspect.
If that 2250 has had someone in the ECM playing with the mandate, odds are it is a bad file and doing damage to the motor. This is nothing to play with, unless you are flush with cash.
First thing I would do while waiting for the reader is to complete an EGR tuneup on both motors, replacing the needed sensors, mainly the Intake Manifold Pressure Sensor and the Exhaust Back Pressure Sensor, both motors have these two sensors, buy two of each. On the 871 there is a video linked to above in the video section regarding your 871, watch that series in regards to the EGR Tuneup, as the 871 has one sensor the 2250 does not, the Differential Pressure sensor, I would inspect and replace if it is original. There are other sensors too, and of course the dosers, but wait on those until you get Insite up and running, no use throwing money away at this point.
I would also do an overhead on both motors, you really should be under the valve cover inspecting the cams and lobes, along with the valve adjustment. It is not difficult to do, there is a video on that too in the Rawze video library at the top of the page. I would not trust a shop to do this overhead properly, unless you can stand there and help or at least observe. If you do not have the tools to do an overhead, you really should invest a few bucks and do just that.
The ISX, once you get to know it, is a very simple motor with a few quirks. But until it is understood what is going on, it can be a bit overwhelming, as all of these new EPA motors are.
If you have not figured it out yet, running off to a shop will drain your bank account quickly, so take the time to learn everything you can about these motors and purchase the needed tools to care for and maintain them. The days of GTO are long gone, and relying on shops to keep your trucks healthy is foolishness. Many of us here were on the verge of bankruptcy before finding Rawze and this site. I was. Time to get your hands dirty. Oh, and welcome aboard!
thank you for all the information i do have insite and i use a nexiq2 but not original, the cm2250 i bought because i got a good deal and been wanting to start working more on cummins, i like them just did not own any in a while.
the cm2250 its a 2012 volvo with a fro16210c transmission 3:42 rears and low pro 22.5 on it runs 70mph and 1500rpm.
i have allready done pm service change crank case filter ,boost sensor ,check for boost leaks , im aware of there fuel pump issues and it has allready been replaced and it idles very smooth ,is there a way to tell when the pump is going out or just replace every so often kinda thing?
the power part im actually looking because id like to have a truck with some more grunt and be able to pull heavier loads easier , allways had truck in the mid 400, truck runs and has no issues.
as far as the ecu i know who did it and they do decent work,but i have been fallowing rawze for a while and i believe he knows cummins bertter then all i have seen and i have learned alot thru his videos ,always said i get a cummins i would like rawze to do tune or advise me on it and thats why im here and looking forward to learning more from him and you and who else is good at cummins.
the cm 871 i will track all the info down from dealer and will start on that one next week or so
