SpeedoHealer v4

Which vehicles is the Speedo Healer compatible with?
All bikes, ATVs, cars, vans, trucks and snowmobiles which have 3-wire speed sensor or 2-wire ground switch sensor.
BMW motorcycles use 2-wire inductive sensor which the SH-V4 is not compatible with. However, we can make custom unit on special order. Please contact us.

My speedometer is analog, will the SH work with it?
Yes, the SH works with both analog (rotating needle) and digital (LCD read-out) speedometers. However, the speedometer must be electronic.

How can I tell whether my speedometer is electronic or not?
It is electronic, if there is no driving cable going to the back of the dashboard (usually from the front wheel) but electric wires. All modern motorcycles have electronic speedometer.

Will the SH calibrate both my speedo and odometer?
Yes, but it is not possible to calibrate them separately, as one speed signal drives both the speedometer and the odometer.
On most bikes, if the speedo is calibrated to be 100% accurate, the odo will register slightly less miles. While this can be annoying in certain situations, one can always calculate the real distance easily after a long trip.
Alternatively, of course, you can get the factory default indications regardless of the used gearing: accurate odometer and slightly optimistic speedo.

Will the SH fix my speedometer in the entire range?
Very likely, as all modern motorcycle speedos have none, or very little linearity error. If you wish, you can check the linearity error of the speedometer by using the SH in Test mode.

I use a different re-calibrator on my CBR600F4i and the speedometer jumps up and down by 1-3 mph at steady speed. Will your SH be better?
Absolutely. The SH uses 32bit real-time arithmetic and 0.001 correction steps , therefore it won’t cause any side-effects.

I use a different recalibrator on my GSX-R1000 and at very low speed, the speedo-meter stays at zero or jumps around.
Unlike the SH, other calibrators simply do not drive the speedo below a certain frequency. With the SpeedHealer, there is NO speedo lag, even on takeoff.

In what regard is the SH the best among the competitive products?
› Widest calibration range along with the finest increments
› Widest in- and output frequency range
› The most accurate calibrator
› Top Speed Memory function included
› Mile and kilometer conversion without any affect to the selected calibration value
› Quick and easy set-up through the on-line calculator, no need for math and special look-up table
› Plug-n-Go Kits are available for Japanese bikes
› The selected values can not be changed unintentionally
› Smallest power consumption
› All leads are protected against improper installation and noisy signals
› Compact and robust design, 100% weather proof
› Detailed documentation and excellent customer support
› The best value for money

I disconnected the SH/removed the battery, do I need to program the SH again?
No, the SH retains the settings even if you disconnect it. The values are stored in Flash memory. Your SH-V4 will always display the calibration value in use whenever the ignition key is turned on.

I changed the front/rear sprocket on my bike and my speedo reads the same at a given rpm. So do I have more speedo error?
Yes. The speed sensor is reading the revolution of the countershaft, therefore the speedo vs tacho readings will always be the same. However, with a shorter sprocket ratio, higher rpm is needed for the same actual speed, i.e. the speedo error is increased.

Can I buy another SH box or a Harness kit separately?
Yes. Please contact the distributor in your country.

I have a GPS unit (or a Bike Computer) installed on my motorcycle, is there any reason to install an SH?
Yes:
› GPS receivers and Bike Computer have a huge lag, therefore can’t show the real momentary speed. The sensors of bike computers send only 1 pulse per wheel revolution while the bike’s original speed sensors can send over 80.
› When your odometer shows more mileage than the actual, you pay for it when you sell the bike.
› If the vehicle is equipped with fuel consumption meter, top speed, average speed or other extended functionality, having the speed signal calibrated becomes even more important.
› Reading from the small bike computer screen can be hard and unsafe, especially at high speeds or low light conditions.

How can I use the Top Speed Memory (TSM) recall function and how does it work?
Press and release the remote button. The top speed is shown on the speedometer for a few seconds, even if the bike is in motion. Keep the button depressed for at least 2 seconds to reset the TSM. Notes:
› The TSM retains its value even if the ignition is switched off or the unit is disconnected.
› The TSM function is disabled in Transparent mode, i.e. the unit has to be programmed first (only on SHv3 and earlier).
› The odometer always registers proportional to the indicated speed.

If I enable the “km/h to mph” conversion mode, will my LCD read in mph?
The indicated speed and distance travelled will be converted, but the displayed units of measure (km/h and km) won’t be changed.

I have an Acumen/Datatool Gear Indicator installed. Can it be used together with your product?
Yes, the SpeedoHealer can be used together with any aftermarket products. We recommend connecting the gear indicator between the speed sensor and SH white wire.

Will the SH remove the speed limiter of my bike (ZX10, ZX12, ZX14, YZF-R1)?
By calibrating your speedometer that has e.g. +8% factory speedometer error, the limit point will be raised by 8% as well. Usually it means that the limit point will never be reached.
If your bike has been tuned for extreme top speed, use the dual-bank memory feature of the SH-V4. E.g. when riding a ZX14 on the street, select -7% to have an accurate speedo, and switch to -90% if you wish to attempt a 200+ mph run on the track. Switching between A-B memory banks is as simple as pressing a button.
Note: The SH does not affect the speed limiter on Suzuki motorcycles with gear position sensor (you need a GIpro w/ATRE or X-TRE to by-pass the limiter on Suzukis).
