through a bit of raw searching, i'm guessing that the 'message length' field (the second byte of practically any aldl communication that tells the ecm how long the message will be) is calculated as the total length of a packet plus 82 (decimal)
i'm wondering two things;
1. am i correct
2. are there any cases that '82' isnt the magic number?
3. are there any cases where an ALDL message could be longer than 173 bytes, in which case, what happens?
