Questions about Datamaster

1. What does the data checksum error mean? Is this an indication that one of the values logged doesn't make sense? I noticed that when I see these, one of the data points has an obscene value (ie 168* timing advance). If so, is this normal?

2. If the EGR is unplugged, code turned off, and the tables zeroed out, will DM still show EGR Duty Cycle percentages? The log I'm looking at shows 12.5% at random times.

Thanks guys.
