how to edit a file without driver

Hello to all.it happens that I read of the ECU and I can not find the driver on the ecm. As you modify the file without finding the driver?

if you know the curves in 2d is not any kind of problem....the catch lies in the time.....you lose a bit more time to make a map but in the end you can too...the drivers are great helps you speed up work so much but in the end you have to always know the curves,as it is not always the sw modification telling the truth

Sometimes you can try with driver control unit of the same group, perhaps with different hardware and soft equal, or vice versa, of course you need to know a little about the shape of the curves as said to be sure of compatibility. Or do you take it as a basis in 2d, a similar file with the driver and you look at the various curves and their changes, and then reporting on your.
