2J013 is correct - my silver VN has a build date of December 1990, and has this paint code. I have a reference that says this code was valid from 1989.

The VS series III tune is essentially the same as the VT tune, it just has some different code to run VS ancilliaries, such as the fuel signal for the trip computer

...or use this control file with DHC11 and you should get a full disassemble. Part of the trick is to look at the code anywhere the disassembler tells you: Indexed Call/Jump at $XXXX, may require a vector table and add a vector table (as seen below the "subroutines" comment in my file) FDS...

If you want to use DHC11, try adding the text in the attached file. It has all the normal vectors, as well as labels for all the ports, etc.

It describes how knock measurement is handled in the later model (VS V6 onwards) control units

I've been tracing some of the VS/VT (16199728 and 16233396) PCM circuits and doing some schematic sketches. They're all very similar, including 16210672. Those 1k2 1/4 watt resistors (shown at 1) are used in digital inputs. Your components 1,2 & 3 are the digital input connected to pin F14 on th...
