Anyone used a STL trans trigger on a Portatree Eliminator? I cant get it to work. Thanks in advance

check your connections, it is just an open closed switch. I use mine on final round.

One thing to note, the practice tree switch polarity must be correct.

I built a long set of leads with alligator clips that attach to the delay box button terminals for my practice sessions.[delay box power is off]

This allows practice seated in the car with the switch you use in competition.

Think of it in this way; all you are doing is substituting a different switch. If the practice tree operates normally with its factory-supplied switch, something is amiss with your switch or wiring.
