I've purchased several ERR cruise commanders and steam railsounds kits to upgrade steam locos without command or sound. The Railsounds instructions seem to me to steer you to a magnet on a tender wheel to drive steam chuff. Some of my locos have smoke units. One has a flywheel with black and white bands. Wondering what my options are for steam chuff input, and what others have done?

have used both serial data chuff and direct to railsounds lite board hall effect or reed switch encoder.
by data- I mean on the R2LC receiver in the engine, there is a chuff input signal that can be connected to a frame common pulsed input (cam driven switch or other).
With a striped flwyeheel- you could use the @gunrunnerjohn's chuff generator board and generate that programmed chuff signal and then with a tether to the tender for serial data- the ERR railsounds will accept serial data chuff from the engine.
This is covered in the manual https://www.3rdrail.com/err-3r...lSoundsCmdr-Inst.pdf

Needless to say, I use the Chuff-Generator for any install I do. I get a true 4-chuffs/rev that way, the magnet and reed switch won't give you that.
So for a loco with no flywheel (and hence tach tape), what are my options? Reed switch near a driver with 4 magnets? What else?
Well, does the locomotive had an existing chuff switch? What is the exact make/model we're talking about?
I have a Williams USRA 4-6-2 and an MTH USRA 2-8-2. The original PS-2 sound in the MTH loco got fried; it currently has a Dallee electronic e-unit only.
How is it the MTH USRA 2-8-2 doesn't have a flywheel?
From the description of the PS/2 2-8-2...

It guess it does. I haven't had that apart in a while. I wonder if it already has the ability to send a chuff signal to the cruise commander?
The Williams loco has a seuthe smoke unit with no chuff and no flywheel.
