[W126 Coupe] Speedometer Change

Dakota Digital SGI-5
The SGI-5 Universal Signal Interface Unit can handle nearly any of your
electric speedometer signal conversion and calibration issues. The SGI-5 can
recalibrate 2,000 pulse per mile (ppm) through 250,000 ppm electronic
speedometer pulse rates, either up or down. The SGI-5 is great for adjusting
aftermarket and OEM electric speedometers on vehicles after changing rear
end gears, tire sizes, or drivetrain changes affecting the speedometer.

Easy to install, very easy to calibrate. I did the installation in fifteen
minutes and with a GPS as the accurate speed indicator, had it calibrated
fifteen minutes later.

Hi Folks

    Tried to replace my speedometer which was faulty and in MPH with one in 
KPH,trouble is one wrecker tells me of the 2000 126's they have wrecked here

in Western Australia only 2 were 560's.

    My old one shows 270KPH in the inner circle,whereas all the 420,300 & 
380 126's only go to 240KPH tossing up to see if one of these can be 
recalibrated economically and successfully,any thoughts most welcome.

 

                    Kind Regards Dan Gardner   1986 560SEC Euro  (220kw)
