First I will say that I am not that familiar with the.cax process and will study it tonight but would like an answer to what will probably be a stupid question.....can you identify a .cax file in a tune/os file which you pull from a vehicle? If so how? The reason I ask, we suspect there is one in there and would like to remove it.

In the mean-time, we are writting over the PCM with a GM fresh OS/cal via Tech II.

Thanks and be gentle :-)
