Soon after the JB1 installation I have noticed a slight vibration (metallic sound) kicking in at 2400 rpm and going away as soon as I go over 2600 rpm. It's happening at 1,2,3 gear and always between that small 200 rpm range. It's not loud and you'd need no music on to hear it and not going WOT as then the engine noise covers it. Seems to be somewhere from the engine bay and it definitely isn't the JB1 cables hitting anything, this is a very clear, metallic rattle. No lights, no affect on performance (to my understanding at least).
Since it's a new car I wanted to give it some time before going paranoid with all its bespoke sounds, noices etc. that I was just not used to before. I also can't be 100% the JB1 was on the first time I heard it or whether it went on the car after it.
I know it only makes sense to remove the JB1 and if it continues have the dealer take a look but being too busy lately I haven't had the time to go to a car lift (I used one for installing the unit on the car in the first place). I also get that this is probably a bit of a ghost-hunting, those little things that mostly go un-noticeable unless you look for them but anyway. Anyone caring of taking a closer hear during that rev range on theirs (normal throttle, less than 40% will suffice to provoke it) and report back will be appreciated. Also, it doesn't seem to make it when it's cold, more often when it's up to temp.
Will try to get a vid to be clear of what it sounds like.
