You can buy turn-key standalone fuel management systems for the CR engines but its pricey.
The thing about fuel map for CR Diesel is the variable pulse modulation can be rather complex. I know there are guys out there mapping their Duramax engines with it but you would need an ECM that is programable. The Dodge ISB170s could be tuned to run with a Mopar programmed 5.9 ECM so long as you were down to replace the connector, which its 89 pins, however not all are use. I think it is close to 72 wires.
Here is a standalone ECM that you can program yourself.
