Jaycar Speedo Corrector
One of our newest forum members, JTHSpace, discovered a very nice, small, reasonably priced, speedometer corrector manufactured in Australia. The JayCar Speedo Corrector is 2.5" x 1.8" x 1" in dimensions, and has a shipping weight of only 3.5 ounces. Here is a link to the product shown at the vendor's website in the United States.
http://www.jaycar.us/productView.asp?ID=AA0376 Here is a link to the product's user manual. http://www.jaycar.co.uk/products_upl...l%20AA0376.pdf If you purchase ten or more units, the price is only $23.00 USD, plus shipping. Is anyone in the United States interested in a group purchase of this speedometer corrector? If so, I am willing to handle the details.

This speedometer corrector was originally available as a kit.
http://www.autospeed.com/cms/article.html?&A=108415 http://www.4wdaction.com.au/forum/vi...?f=10&t=141776 However, you can now buy the completed unit, which is smaller, and you don't need to do any soldering.

The Jaycar Speedo Corrector is wired into the RX3 the same way as the SpeedoDRD unit from 12oClockLabs.
The RX3 employs a sending unit on the front wheel which uses has three wires. One wire contains 12V DC, which powers the sending unit. The other wire is a ground wire. The third wire transmits pulses from the sending unit to the Siemen's speedometer. We would tap into the three wires on the opposite side of the connector, at the wires that lead to the speedometer. One wire feeds 12V DC to the speedo corrector, and one wire feeds the ground connection. One wire feeds input from the RX3 sending unit to the Jaycar unit. One wire feeds the corrected signal from the Jaycar unit to the speedometer. The Jaycar unit has convenient holes in the housing, so we could attach the unit under the dashboard with zip ties.

Tapping into the wires on the dashboard side of the connector will allow us to easily and quickly replace the stock sending unit if it becomes damaged.
Setting the S1 and S2 potentiometers allows you to fine tune the Jaycar speedometer corrector for excellent accuracy, allowing you to change tires, wheel sizes, et cetera, and still obtain a very accurate speedometer reading.

I was interested, up until it said not to get the module wet. I'll pass on this one. Thanks for sharing it.

Spud,
I'd be interested in 3 of them. If you decide to do a group buy, let me know what your Paypal is or how else you'd prefer payment. EC |

I don't think it would be that hard to waterproof the case. Also, one could mount this unit under the pillion saddle, and extend the wiring to the dashboard. However, I do appreciate your concerns.

Duly noted, Veteran. The next cheapest alternative is the SpeedoDRD from 12oClockLabs for $70, and I think this unit is much better protected, and much easier to calibrate.

SpudRider, what do you figure delivered in the U. S. of A. is going to cost?

I sent an email to the vendor, but I don't expect a reply until Monday. The shipping weight for each unit is only 3.5 ounces, so I think the individual shipping cost on ten, or more units should be pretty reasonable. Then, of course, one would need to add the cost of shipping each unit to the individual buyers. However, the SpeedoDRD unit costs $70, and I'm sure the final, delivered cost of this item will be much less than that. I would guess the final, delivered cost of this unit would be $35, or less.

If Qwerty wants one of these controllers, we are already half way to the minimum order of ten units. Of course, the more we order, the better, since the individual cost of shipping each unit from Australia drops as the number of units increases.

I pretty certain applying some RTV around the wiring grommets and the case seam will seal this unit very well. Plus, I think the unit will be very well protected, even while washing the motorcycle, if it is located under the dashboard, behind the windshield. Of course, mounting the unit under the pillion saddle will provide even more protection from moisture.

I'm in.
Have we ever confirmed how this will also effect the odometer? I know it sounds like an obvious yes. But on my Triumph Sprint ST the speedo reads 5% fast confirmed with GPS but odometer is almost dead-on with GPS data. The speedo error is therefor programmed in on purpose. |

I think the only way to know is to ride a measured mile, and compare the reading on the odometer. I have compared my speedometer to my Garmin GPS receiver, and the speedometer is definitely a little over 10 percent 'optimistic.'
