I did this in order to recalibrate a 180 kmh speedo into mph. I've attached
a copy of a PowerPoint97 slide with the template in a variety of colours.
Feel free to add this to the how-to. To fit the template, you need to get
to step 9. To line it up, just make sure that 50mph lines up with 80kmh on
the original and 100mph lines up with 160kmh. The lowest speed I've put on
the mph template is 30mph since below this speed the standard kmh speedo is
non-linear.
If you are just replacing warning bulbs etc, then step 8 is as far as you
need to get.
Items listed in c. and d. just pull off, those in a. and b. have to be
unclipped as well
Also be careful when replacing the panel below the steering column. You
should make sure that the air vent hose is pushed onto the vent outlet
located up behind it before pushing the panel into place.
ftp this file:
speedo_template.ppt. I can make this available in other formats if
you do not have PowerPoint, but I wanted to leave it in this format since the size (actual dimensions)
may change if I convert it. Just drop me a line. --Steve
Apparently the speedo is driven by a pulsed squarewave which pulses both
positive and negative volts at a frequency proportional to the speed of the
car. The odometer integrates this to turn this into elapsed distance. If
you insert some clever electronics to reduce the pulse frequency by 5/8 to
convert the speedo to mph, then the odometer follows suit. Obviously since
your odometer reads km before you do this, then you will be adding miles to
this figure.
