Hi!
I had a problem today with the ram of a client, I can not download the ecm, there is an error message. It takes a corresponding prog of the databank. When I try to see DTCs they are not available.... If I flash this random prog to ecm, can i have acces to DTC?

The message you get when trying to read the truck is normal. It is telling you that it isn't going to read the actual calibration from your ECM, but will instead supply you with a stock base to work from. It goes on to warn you that if you already had a custom tune in the ECM, you will lose said custom tune since it obviously isn't reading it, and you would forever lose those changes. Standard procedure with a lot of these trucks. Just be sure to save a copy of the stock base and keep it somewhere safe where you will just leave it alone, then, any time you need to make changes to the calibration, just keep working from the modified file as you progress. You will never be able to read a tune from the ECM, even after you tune it with HP Tuners. It will always just supply you with a stock base any time you try to read.Quote:

What DTC are you looking for?

Probably means they aren't mapped out for that ecm/os. You will have to use customer defined parameters or find another way to do what you need.
Also be careful with that supplied file..... if the truck has a programmer or another "tune" in it then if flashed with the file you got supplied it will be back to stock.
