Programing throttle detents help needed

[Imzzaudae]

Thr 53(0235) (P /H F2 /RF1 ) LOCK(THR,0%)Unlock (THR)

I use a CH Yolk USB , CH Rudder pedals and a SFS combo throttle unit all working together well.

I need to add the above line to my SFS throttle config file
in flight sim 2002 but need a little reading on the subject.

Any one know of a good tutorial and where to get it?
