Re: 16176424 PCM pinouts

Thanks Richard and Matt for the info on the VR PCM.

So, the 16206305 is more properly an equivalent of the 1227165 
(the 1227808 is often referred to as a 1227165 without the SXR chip 
[SXR = 8192 baud transceiver]).

Also, as I understand it, the VT V8 uses the VR's PCM, but the VT
V6 used the newer 3 plug PCM that has a driver per injector. This
PCM is also a flash unit with a much smaller CALPAK unit than the
808's MEMCAL with EPROM. Correct?

If someone has access to GIFs of these newer Holden PCMs (cases 
and internal PCBs) I'd love to get a hold of them and make them 
available on my web site. For me a picture really is worth a 
thoussand words.
