I'm trying to gather ideas for what might be included in a diesel board. Obviously, I'd like to fit as many functions as I can without making it so expensive that nobody can afford it. 
I don't know if it's possible within price constraints but a Mars light function would be useful, at least for those non-Lionel TMCC engines that don't have a good lighting board. A lot of past 3rd Rail diesels just have a blinking LED. Scott Mann's now using the Ngineering Mars light simulator board but this is a relatively recent improvement.
We're thinking of putting the Super Chuffer in the earlier Legacy FEF (I think about 2009) which has synchronized smoke and adjustable smoke output. Any issues with this application? We'd like the idle smoke which it, the FEF, does not do.
Thanks, Chuck
I have thought about this too but the FEF3 you mention is Legacy equipped, not TMCC, although it's an early version of Legacy. I looked at the control boards in mine and although they appear very similar to TMCC boards I could not figure out the pins and in any event it's clearly using a different code. Over to GRJ to say whether you could get the smoke function at idle using a Superchuffer board in this model.
