Thread: gps v speedo

Speedo - after checking it against the GPS to work out the error. In the three Foresters we've owned, 118 indicated is 110km/h.

On my XJR1300, 110 indicated is 100km/h,

On my L322, 100km/h on the ScanGauge digital speedo is 107km/h on the analogue. However, it should be noted that I had the speedo needle off to dismantle the instrument binnacle when fitting a new ribbon cable. Dead pixel fix

Although I marked the needle position before removing it, doesn't mean it's back in exactly the same spot.

Hi,
I drive to my GPS. I use a dash mounted Garmin, not the factory unit in the D4. My wife has a Mazda MX5 and her factory GPS won't display speed.

I do. If I were to drive according to my speedo, I would be doing 94 while indicating 100. Try that towing a caravan on the Bruce, don't like trucks hitching a ride in the bathroom of the van.

whats this speedo thing you mention?

My D3 speedo is very close to GPS speeds. My old Tojo 'tilly, with 15" wheels, is down by 10 kph on the speedo. This lessens whenever new tyres, Maxxis Bighorns, are added.

GPS speedo and Hema both show same speeds.Speedo also logs peak speed traveled

Speedo, i have checked it against a GPS and 100 indicated is 98 actual .

Speedo - I went into the CCF and modified it so my Speedo and True Ground Speed are a match.

On the bikes I have Speedo correction units to do exactly the same.
