Is their anyone on here with experience and knowledge of writing and coding ecm files? I'm wanting to know if it is possible to write a completely new file to run a ram 6.7 ecm on a common rail four cylinder engine? is it possible to just take a Cummins ecm calibration code from a on highway industrial application (ISB3.8 - ISB4.5) and load it into the ram 6.7 ecm? any and all help is greatly appreciated even if its just getting me pointed in the right direction. Thanks in advance!!!
