My first post on the forum! Because I'm in need of help!

I have an S13 Silvia with an SR20DET engine.
I installed a Bee*R 2-Step limiter yesterday, but it doesn't want to work correctly. I soldered all the connections. I'm 90% sure I have the wiring correct.

I followed the guide here: Bee R Rev limiter install *Guide*
I know it's not for my exact car, but my ECU has the 16p 14p 16p 18p pin out the same as his.
Plus, in the instructions included with the Bee*R, it listed the same pin connections for my Engine.

It revs to the set limit (2500) and engages as it should, but the revs only cut and bounce as they should for about half a second.
After which they completely drop, almost as if the engine has stalled, then cut back in briefly and raise back to 2500RPM, before completely cutting out again and this repeats endlessly.

The light on the Bee*R blinks when it's cutting the RPM's, as it should, but stays on when the revs drop, which I thought was really odd.
It's as if the Bee*R cuts the revs well, then 'freezes' causing the revs to drop, then kicks back in briefly before 'freezing' again.

I've uploaded a few video's of the issue to help try and get it resolved.
The video's
Feel free to share the video's to co-workers or whoever might be able to help.
In one of the video's there is a brief period that sounds like the Bee*R is working correctly, but it doesn't even last half a second.
I do not lift my foot off the throttle at all until the very end of the video's!
Pardon my language too in the final video lol it let out a whopper of a backfire and startled me!
If it helps, when it backfired, it let out a LOT of black smoke smelling of fuel.
So maybe the Bee*R is somewhat flooding the engine? I'm not sure exactly how they work, so hopefully someone can help
