    03 5.9 Cummins

    So I was going through my files and I had to order a blank ecm for my 03 cummins race truck. I was wondering if anyone could point me to a 03-04 file that is a base or just a starting point. The truck has triple turbos in a two stage set up and dual pumps with 250% overs with a 6.7 rail sensor. Just looking to see if I could use an 06 file to start.

    No, a 06 file will not work.. two different ECMs, you have to go to the dealer and get it flashed to the vin/trucks
