I found my not very accurate scale finally and it says that the OEM system is 28.8 pounds.The OEM axle-back section weighs in at 13.0 kg, so about 28 lbs.
At least that's what these guys measured:
Were you in Advanced efficiency mode? It does exactly that in A mode.I had an episode 2 weeks ago with the transmission "jumping out of gear", then re-engaging once I let off the accelerator. It did this twice, while I was cruising on the freeway. I do not recollect anyone else reporting such behavior. For now I will assume that this is the same as the CAN bus fault.
That was my fault for not explaining what I experienced properly.I misunderstood what happened in this case... quite strange behavior...
Possibly it's some emergency charging logic. Get the rpms up to increase alternator output? A single missed can message will store a code, missing several will trigger all sorts of errors and warnings.My hope is that it went into sailing mode for a moment as I let off the accelerator for a slight downgrade, then when I tapped the accelerator CAN bus errors resulted in the transmission not re-engaging. I did not think at the time to see if the problem happened in N mode. This behavior happened twice and has not been observed since then.
I did pop open my center console in order to install a DNAR switch and a harness for a controller for my Fiammenghi valve controller. It is alternatively possible that this disturbance created some fault on a cable that carries CAN bus signals. Note that the Fiammenghi adapter does not touch any CAN bus signals, as the DNAR switch on an MY2018 Giulia lacks any communications.
FWIW: The center console is massively complex and overweight. I wonder how much of the 100kg weight reduction in the new GTA comes from getting stuff like this under control. I also wonder to what extent drilling out plastic bits could lighten it. It appears that a lot of plastic is solid for the purpose of making molding easy and cost effective, rather than for strength or rigidity. Also, in many places there are many layers of plastic apparently to make assembly easier
