Anyone who deals with commercially available SCOM solutions will sooner or later come across a point that is repeatedly discussed in forums: The module must remain permanently connected while driving.
Why this is technically implemented this way
Since an SCOM continuously manipulates the speed value, the limitation immediately reappears as soon as the module is removed or the connection is interrupted. It is therefore not a one-time activation, but a permanent signal manipulation.
One-time activation instead of permanent carrying
The M-JET Speed Limit Remover solves this differently: The activation happens once, after which it remains active, completely without a permanently installed additional module.
