Has anyone who owns and runs the AF 4-6-6-4 Challenger tried running it under the latest upgrade for Legacy Command(ver 1.51)? The new version has a new application for Flyer Pullmor Steam and Diesel. I am curious as to if the new app has any new options/functions available for the Challenger... Just wondering if it is worth going to the effort to upgrade my Legacy Command system, presently running vers. 1.4!! Being new to the Lionel Legacy Command system, it appears to be a bit of a challenge doing the upgrade(I just bought this used system in Nov.). I have all the connections but do Not have the black memory module(the blue and white modules were missing). I guess I would need the upgrade to properly program the new Y3s and make full use of all their capabilities, which I am contemplating very seriously. Any comments or advice is appreciated. Thank you... Laurin.
