[quote user="wjstix"] Just to be sure I'm following...when the engine / decoder is set for 128 speed steps, it runs in reverse of the direction it should, right? So, have you tried at that point reading CV29, and reprogramming that CV to one number higher (or lower) and see what happens? So if CV 29 is 34, change it to 35? If changing one CV has somehow reversed the polarity of the DC power going from the decoder to the motor, I'd think changing CV29 by one number would fix it...or just swap around the wires going to the motor. <div style="clear:both;"> </div> [/quote] Stix, No.  That was literally the first thing I tried over a year ago.  It only runs in reverse.   CV29 has not effect on this problem.  On 28 speed steps there are no issues.  The problem has something to do with CV 18 having a value of 63.  No idea why.  It has been confirmed on my NCE system, Rich's system, and I believe Randy's system as well. and both NCE and Digitrax systems at BLI.  Of the 10,000 possible addresses, 36 have this glitch.
