Okay, so I have recently acquired a 98 Ram 1500 4x4 that was converted to a 24 valve cummins and a 47RE tranny. The VIN is for the original V8 gas motor, so I can't use it to program the ECM that I just discovered is "unflashed". I have basic functionality, (starts after a delay and runs okay at most speeds) but if I could get the ECM in line I'm betting life would be easier. I tracked down the owner who did all the conversion/mods to this truck and he is deceased, and there is no surviving documentation on what was done.

So in a nutshell, is there ANY way to get an ECM programmed without a VIN?

 

Have u tried using the vin from the motor to reseach should ve the same info as the vin for the truck

 

Trying to track down the info based on the engine plate now. The Dodge dealer/repair people out here aren't the sharpest I've ever encountered.
