I have successfully "ID" the TMCC engines in TMCC system and they run correctly. I then enter them into my DCS handheld as instructed and they appear on the screen as they should I select a TMCC engine but nothing happens they will not run. The Legacy unit registers the signal to the engine. I have the MTH cable to connect the Legacy unit to the TIU have run the ground wire to the TIU from the Legacy base, I have done this with several TMCC engines with no success, what is wrong!
