I finished installing six disk magnets on the driver #3 of my BLI UP 4-12-2 to get around BLI's inability to generate a synchronized six-chuff with their flywheel pickup. I planned to use a Hall Effect sensor, but a reed switch worked much better.
Of course, because the Paragon 2 in this engine was set up to divide the input count by three, I get two chuffs per driver revolution, so I must either change decoders, or find out if the Paragon can be changed to eliminate the divide function and correspond with a chuff per each input. Does anyone know if an undocumented CV change, of if a point on the board to connect to after the divider could solve this problem?

I called BLI to ask if the divide-by-three circuit could be bypassed, but it had to be referred to another tech, so am waiting. The only thing I know yet is that the divide circuit is set as part of the firmware. In two cylinder engines with the usual gear ratio of 24:1, it is divide-by-six.
WOW would also be my choice, and I have some on hand, so am prepared for a negative answer.
Disreguard this, I was thinking of Baldwin #60000 with the 90-135-135
The answer from BLI was negative, no way to get 1:1 pulse/chuff. But I also got out my scope and went all over the decoder board with no success.
The Wow transplant into the 4-12-2 went well. I was able to set up the lighting with the same Rule 17 dimming, but I put the cab light and red light on separate throttle functions.
Regarding sound, I found a recording on Amazon to use as a model for the 3-3 chuff. The Wow whistle called "reconstructed ATSF 6 chime" sounds very much like the recording, so am using it.
The chuff is reliable with a red washer added to the axle to limit sideplay. It wasn't necessary, but I decided to take the smoke generator out since I never use one.
