I have a rdg heritage unit with ps3 that is acting strange. When lashed up, or more properly mu'ed, after a few laps it starts making thiis weird clanknig noise and the lead engine sounds don't seem to work. The noise stops when thelashup is sstopped. Additionally this engine seems to get lost and not recognized by the dcs fairly often. I have done the factory reset and the feature reset.
The tiu is an older version but the software was upgraded at the fall dcs user's group meeting and I don't seem to have a similar problem with other engines.
Is there any known software glitches with the heritage engines? If so is there a download-able fix? Engine #20-20271-1
