Isx to x15

[Washbour]

Good morning,

My names Anthony washbourne... I've been helping a friend with a 2012 western star isx cummins that engine went after a ton of miles.. deleted and such.. he got a sweet deal on a 2020 x15 low miles and swapped it in. He bought the new ecm plug being the x15 came with the ecm and another friend followed the diagrams to pin it to the truck harness.. everything runs great he had a new program done in ecm because the ecm was looking for after treatment that's not there.. so it runs has throttle all dash light body lights everything. But 0 guage functions. Volts tach temp etc ... trying to figure it out.. pls help ...

Thank you

Need to see if engine is 500K data link if so youll need to change it to 250K .... This is done with calter m.. We have done it a few times in or shop with the help from Rawze on some input settings but major issue was with data link..

I talked to this person on the phone...

== It would have been FAR LESS HEADACHE AND EFFORT to use the old CM2250 wiring harness, older model turbo, and older ecm on that newer engine, then have a custom program made for the older ecm to run the newer engine, rather then trying to re-wire everything.,


Regardless at this point, ...
= They need to copy the program from the replacement engine ecm, and from the old ecm. Send them both to me for review and to help get the can-buss speeds, other vehicle addresses etc. straightened out.
