I have an SD7 and a SD9. Both P2K's. both run well, and I like them. I bought the SD7 used, and it already had a decoder in it. it is MFG=11.
The SD9 I bought new and put in a TCS (MFG=35)
I have tried and tried to get them speed matched for consisting, but the accel on one, and, well, it just has not worked out.
I have not taken the engine apart, as there probably is nothing visable on the decoder anyways(?)
I am considering buying another TCS to match the two, and then will have a spare "chip" for future engines. I was just wondering what some of you may think.
wheeler it is MFG=11.
I believe that this means it is NCE.

MFG #11 is NCE. TCS Is MFG #153. Here is a link to the NMRA list of MFGs

I have 2 engines with TCS T-1 decoders. Both have the same problem consisting. I can't enter them into the consist in the "reverse" direction, only "forward." If I leave the consist active when I power off the layout, sometimes their direction in the consist reverses, but I haven't found this to be, well, "consistent."
I don't know it TCS has fixed this bug, but if you're using T-1s, be aware that this is a know problem.
I never put those 2 engines together in a consist (one is a GP9, the other an F7) so I can work around it by always arranging my consists so that they're going forward, but it's still a nuisance.
It takes an iron man to play with a toy iron horse.

Older TCS decoders either T1 or A4 had a consist problem. Version #37 seems to have fixed it. There is a workaround though. After setting up the consist the way you want to run just cycle the power off and then on and they will run in the correct direction. An easy way is to just tip the loco to one side so the wheels come off the track and set it back on.
