New Gauges Spedo incorrect MPH Issue

[Speeddog]

The sensor has a magnetic core, wrapped with wire.

When the steel bolt head (DSS) or post (SSS) moves past the face of the sensor, it creates an electrical voltage/current signal.

The ECU/speedometer reads these pulses and calculates the speed.

The sensor cannot 'see' a stainless or Titanium bolt head, as they have, respectively, not enough iron or no iron.

ok so my point exactly. Ti bolts wouldn't be seen. so you could put the proper amount of another metal or magnet or whatever the sensor would see.

Back on the old forum I had remembered someone talking about this but it looks like the thread had been deleted.
In Theory I could put in two steel bolts.  Would they be close enough to the sensor to be read?

i think all the bolts would have to be spaced evenly. so just adding two to the current four would not do it IMO

My red-neck friend suggested this work around for fixing the spedo

I'm happy to report that my spedo healer worked, in fact the spedo is now more correct than the orig

What speedo healer did you use?  Link?

[Ducatiloo]

I bought this one

Maybe this is a stupid question, but how do you adjust this to be correct? What's the input?

I used my gps to calculate  the real speed.   ((GPS/spedo)*100) - 100 = percentage to adjust by.

There is a button and led on the unit.  You go through a series of button pushes while watching the led to set the correct percentage.

I think I might get this because it is always a mystery what my real speed is.
