The other day at the club I was running an engine with my Legacy and another member was using their Cab-1. We both had different engine numbers however when he pushed his horn button on the Cab-1 my horn blew, and when he changed his speed my engine jerked. If I blew my horn his did not respond. like wise his did not respond to any speed changes I made.
I changed my engine number and all was as it should be.
I believe their cab-1 has an issue.
What does anyone else think?
