What is the procedure for removing the shell from the EMD E7 locomotive?
I've removed the coupler mounting screws and spread the shell, using toothpicks to hold it away from the chassis, but it doesn't come loose...

Some Bachmann On30 locomotives come "equipped with Tsunami sound technology".  Do these decoders have all the features of Tsunami aftermarket decoders, in particular, "function mapping"?

I'm trying to remap the brake feature, (F11 from the factory), to F7.  According to the manual, programming CV 41 with a value of 128 should do it. 

I've done this with several Tsunami's that I've installed in other engines, but I can't make it work with the factory-equipped 4-6-0.

I'm "Programming on the Main", (POM), with an NCE Power Pro 5-amp system.  The engine jerks to acknowledge receiving the update, but doesn't change its performance.

Any help will be appreciated!
