I'm betting nobody will answer this one even if they know, but here goes:

Has anyone figured out what the bytes in red, that are always '00', are for?

55 59 20 00 00 00 88 cb 00 00 00 a9 05 22 0d

The green ones appear to be the fuel rate. The blue ones are timing. The very last two, in black, are engine speed/2, 0.125RPM/bit.

I'd just try stuffing numbers in there to see what happens, but I can't afford a new vp44 if I screw up the PSG by doing so.
