oiltronic, thanks for your reply.
mmm looks like it is not easy to get it.
may be the question is, does it support the PGN 0 TSC1 like the CAT? I just need to take control for the engine RPM.
I did what you said for a Renault DXI engine however for that engine I was not able to set the RPM with the PGN 0, it was not a request I just wanted to do it but no luck...
I do not have the truck right now, that is why I am trying to get as much information as I can.
if you can advise about the PGN 0 for the cummins I really appreciate.
thanks again
