Yeah, it's the 8625.  I thought it was interesting that 
some ECM's would use 4000 and others would use 2000. 
I forgot to mention the VSS buffer between the VSS and 
the PCM though, I wonder what that does.

Was talking about a 730 ecm.  I consider the 2000 as close enough, is all
I think it can be worked out into decimal points.

I'm talking about two issues here, the 2000+4000 ppm, and how to inferface
them, for ecm transplants.

This is on your 8625?..  The 2000ppm.
