Is there any chance a column could be added to the 'Calibration' Tab that not only shows the Checksum, but the 'CVN' as it would be displayed in a Tech2 and in the V2 when viewing the CVN? Since the CVN is something that would be the same in all trucks assuming the data is the same, it's got to be something that can be calculated outside the ECM,a nd would be very helpful to figure out what tune is in the ECM for those cases where you can't read it (such as LBZ DSP5).
