Speedo Healer
 

I bought a speedohealer for my hawk, read alot that they show way to mouch on the clock. Installation wass easy took only 2 mins, but my question is, any one know how mouch the original speedometer show to mouch 8-9-10% ?

I know the right thing to do is to dyno run it, but aint one arround atm.


Thx.

I just used a GPS and speedohealer's online calculator to figure mine out. (I also did a sprocket swap, so I can't tell you what the OEM part of that was)

http://www.healtech-electronics.com/ click on speedohealer then online calculator

ride with a person with a known good speedometer (or follow a buddy's car), reset your trip meters to zero ahead of time. Ride a good 20 miles or so, then compare odometers. If your's reads 22 and your friend's reads 20, you are off by +10. IIRC, you would set the speedo healer to -(1-(20/22)) ~ -9.1%. Anyone?

Do another run afterwards to verify. JB

I used the local speed trailer set up by LOE's to check mine.

The calculation cheat sheat that came with the unit was pretty accurate. Give that a try first.

My Garmin attached to the tank via suction cup showed I was off 10%. I checked every 10 mph from 30 on up to 100. So when the Hawk showed 60 I was actually going 54 according to the GPS. Every reading indicated almost exactly 10 %. Hope this helps

Math is a funny thing. If your Garmin showed 54 mph and your speedometer showed 60mph, your speedometer is +11.1%, to get it right you must reduce it by -10.0%.

OK Tweety - what did I do wrong here :)


54x=60
x=60/54
x=1.11

60x=54
x=54/60
x=.90

I see where you are coming from. I am a teacher and understand those numbers, but not a math teacher. I was more interested in the estimation thing. More the Life Science type. I only care enough to keep myself from getting a ticket. I just needed to know how much over the indicated I could go and not get bothered by the LLEO.

do the distance test d=r*t, d and r are directly related.

Sorry to hijack, and I am interested in this as I have a speedo healer to put in. BUT...Holy SHiite! Another SH owner from Springfield, IL!!! YAY!

anybody had any experience with this one?

Nothing wrong with your math... ;)

Nope, but considering the specs & price, go for it... The "mechanics behind" them is the same on all, reduce the modulated lenght of a square wave... ie PWM... So it really cant go wrong in too many ways...

EDIT: Only caveat is that doesn't look to be sealed from weather, which is bad... It is, so no problem...

Gonna have to meet and ride some of the 3 good roads here in flat straight land!

Problem solved. Had it on a dyno run last friday. speedo wass 7,1% off what my speedo showed, so now it shows the right speed all the time :)

Also had it tested with hp and max speed.
115hp on back wheel
255 km top speed.

Gonna change the rear spocket now -2 teeth down, should be arround 275-285 top speed then, but time will show.
