XD Elec Speedo Calibration
Wondering if anyone knows anything about the electronic speedos in the XD.
The old 4.11's and 295's have me going about 120@80kmh! and the speedo cogs for the toploader cost a small fortune and still can't get it low enough.
I was told an instruments company in Perth (Tisco) can recalibrate them?
I've got the sucker out and all I can see is a little access hole on top of the speedo unit which has a small rheostat inside. Is this what is used to calibrate it? or is it something more hi-tech?
I've got the hand-held GPS on the dash board so calibrating it whilst driving would be easy if I would be able.
