Speedometer programming

[Gregory OConnor]

I dont think the dips are adjustable to do a fine tune???? You may be
able to find settings that will fool the speedo to read closer to
actual but factory set for components installed. I think Bob has a
good point that there must be a input fault if the dip setting you
now have proves to be factory correct?????

engine/transmission are both electronic, and putting out digital
data. There is a separate box containing a circuit board, attached to
the "Cal" hole in the back of the Speedo, and the dip switch settings
have to match what the Cal module is providing. I'm hoping someone
here has had occasion to obtain the settings for a circa '90
8V92/HT755 combo, so that I could try something different. 256
possible combinations for those 8 switches...
