Phantom of the Opera
I want a electronic speedometer, have a 4000 ppm generator for the old speed density computer....so want to take that output from the counter OR the computer that feeds the cruise control....which is a squared off pulse at TTL....
so I want to make a digital speedo display with that signal....
it will have to be 110% accurate till light speeds....
no debate, accurate.....so what I need is a parts list and schematic for the display/converter.....
my mechanical POS is all over the map above 70 mph....:shocking:
for that matter, I want to do the same for a tach, using the same engine signal as stock.....
