As soon as I'd fitted a decoder to my Atlas Master silver series U30C I realized that my BLI SD40-2's were very poor performers so I've done something about it.
I've fitted a Lenz silver series decoder along side the QSI (actually on top) to run the motor and extra lights (ditch especially). The reason for the Lenz is I want asymmetrical DCC http://www.lenz.com/products/decoders/currentdecoders/silver.htm and their very thin.
I had to fool the QSI decoder into thinking it still had a motor to run, if it didn't it wouldn't enter neutral ( no cool air let off wasn't good) and the headlight wouldn't dim, so I wired about 100 ohm resistor across it ( it gets slightly warm)
Now it runs like clockwork even the noise it made has gone ( I posted about two years ago that they had a horrible noise in reverse)
Before I had to get it to speed step 5 before it moved and it shot off like a rabbit now it crawls along at speed step 1.
These BLI's are the first version when all the sueing was going on and they had to disable the BEMF functions. I know I could send them in for a new chip but that wouldn't get me the Asymmetrical nis or the ditch lights.
I shall post some pics when my LEDs arrive of her running.
