Slot not showing in game

Good afternoon,
so, I've worked on a small mod where I can swap around the blow off sound for the old Pessima.
My only problem still is, the slot wont show up in game, funny thing is, I got it to work once, I rebooted the later, and it didn't show up anymore. Now I've been trying around different things in the engine.jbeam of my car, but no result so far.

Here is the slot for the Bov in the ECU of the car (this is a Vivace I5 swapped Pessima)




I had the slot in the engine before, but I swapped it to check if it works in the ECU, which makes 0 differece.

Any help would be appreciated

 

The jbeam itself is completely fine, the car drives and makes noise, as it should (it´s within the engine.jbeam of the car)



EDIT: I fixed it, a zip file within the unpacked folder containing an older version of this mod was the cause of the jbeam not being updated.
