Your welcome ;D I guess you don't see this onboard RFI suppression much in US models.
I did try an LM-2S in the Walthers loco I have (with RFI suppression fitted). Yep, the LM-2S hated it, awful buzzing from the motor and it wouldn't move until the throttle was at about 60%. To be semi complete I then put in a TCS decoder I still have lying around to see what would happen. More buzzing but it moved at a much lower throttle setting so even TCS didn't like the RFI suppression. I might try bypassing the board and see how it performs but I'm in no hurry to do that.

Update.
Heard from my installer regarding pulling the factory circuit board and wiring the LM directly. He said the unit now runs very well with no sputtering. He is going to do the other B unit and then we will take them to the club layout and run them for a couple of hours and see how they do. Having passed that test, he will then do the A units (more time consuming because of all the lights, hence the reason to test the B units first).
Next time I will know better and dump the factory board right away. Live and learn!
Thanks to all who took part in this discussion.

I chunked all the factory P2K and BLI boards that were in my locos so I can't comment on before and after. Glad to hear it all worked out Mike!

Well, about that.
Turns out that even removing the boards didn't help. With the LM-2S connected directly to the motor the engine still exhibited this erratic stalling behavior. It's somewhat baffling, because now it appears that it has to be either the module or the motor.
I talked to Tim about it at length a couple of weeks ago. He gave me some other things to try, chief among them is trying an LM-3S. I'm now waiting on the results of that test. Sheesh, I'm starting to think I may need to replace the (brand new, factory) motors if this latest test fails.
Will keep you posted.
