Unfortunate speedo healer side effect...

[barijack]

I did the 520 -1/+2 sprocket conversion last week and also installed a healtech speedohealer the next day. Well today, i was showing a buddy of mine how the SH worked and got to the lil red button that recalls the top speed (which at the time was 85mph). After a couple of pushes, i realized....MY ODOMETER WAS ROLLING FORWARD! About 1/10th mph per button push....has anyone else noticed this?

I know that the speedometer and the odometer are essentially ran off the same sensor circuit and it makes perfect sense that it does this. But i think its ironiclly funny that an item that is suppose to correct the speedometer and odometer will actually add miles to your odometer when used in abundance.

Is that really an issue though? The bigger issue I've noticed is that the odometer shows less than you go.

well, no its not a 'big' issue, yet still annoying. as for the odometer reading less than it should, if the SH is calibrated right it should read accurately. I dont see any reason why the odometer would read less if the speedometer was actually reading properly.

The reason for this is as you have already said before... they run off the same signal. In stock form, the odometer is incredibly accurate while the speedo runs ~10% higher than actual speed. By correcting the speedo to read accurately, you are then of course making the odometer read lower than actual distance traveled.:thumbup:

Hope that made sense... pretty tired after being at the track all day with Wavex, CaliRider, DefyIntertia, & Hellgate. They all hauled a$$!!!

i suppose that does make sense, but you would think if they run off same signal, then how could one read accurately and the other not....why would they build it or allow it to be this way.

They do this intentionally because it is illegal for a speedo to read too low from the factory, so they accomodate the possibility of error in calibration by erring on side of caution with a high setting.

Obviously in the ideal scenario, both would be spot on accurate. Unfortunately this is often not the case. My new Triumph is a solid 5% off, my FZ was easily 10% off.

guess ya learn something everyday....sometimes a couple of things. thanks guys

Sorry to revive an old thread... but if you just used the healer to get back to the factory error after a sprocket swap. Wouldn't the odometer be accurate then or no?

It should, yes.
