Recently my Bach HO mogul developed a program problem which started giving a 'code 2' warning (whistle/headlight repeat in twos over and over/no movement unless address 3 on loco. Long address #1908 now causing new problem. Long story short: member over at Bachmanntrains.com said put CV 29 (table A) to 38. It worked ! And Tsunami manual states a 'code 2' trouble as a software problem needing to go back to Bach for fix. But, why was it originally at 50 in table ? AND CV 29, Table A shows value 38 under "Use speed tables" column as NO, and "Analog" column as YES ! plus 28/128 Normal. Why does a DCC/sound loco now need Analog 'on' ? Why do 2 other DCC locos remain at value 50 in table ? !! What up wid dat ?
