2004+ Digital version will not work with 2011+ Softails and 2012+ Dynas

Just found out 2011-2012 softails and 2012 dyna use CAN bus technology and won't work with 2004+ digital version micoTach. Sportsters will probably switch soon too.

The TC88 standard version will work a with a singlefire tachAdapter.

No more microSpeed Speedometers

I am completely out of microSpeed Speedometers. I will not be making any more until I get the redesign complete. I am working on it; but it is going to take a while to get new screens made which will eliminate all of the problems.

The website still needs to be updated to remove the ordering; but I hope todo that soon.

Digital version microTach may stops after 5000 rpm

I have resolved an issue with the digital version of microTach's produced before July 2009. The issue occurs on Harley bikes model 2007 or later.

Harley changed the coding on the digital bus signal in 2007. The result is that the microTach will operate normally in range 0-5000 rpm. At greater than 5000 rpm the microTach will only display the last reading of 5000 rpm, ignoring messages above 5000 rpm. (5500 on sportsters)

MicroTach's produced after July have resolved the issue and operate normally across the full range.

If you have the issue on your bike, I will replace the unit with an updated version. The simpliest method for replacement is for you to order a new digital version online at my website Please indicate in the transaction or via email that this purchase is for replacement issue. I will ship out a new unit ASAP. Once you have the new unit; pull the old one off and replace with the new unit. Mail the old unit back to me and I will refund the full cost of the previously ordered unit. The old unit must be returned within 60 days of ordering the replacement unit in order for me to process the refund.

If you have any questions or issue please email me.

Thank you and sorry for the inconvenience.

microSpeed production on hold

A couple month ago, I put a hold on all microSpeed production. Primarily it was due to 3 factors.

1. Touchscreen sensitivity was not consistant in all environments
The touch screen temporarily stops working, if there is excessive moisture on display or user; if casing is touching other metal. This was causing alot of customer issues and I wanted to solve the root problem before exposing more customers.

2. I had at least one field failure of unknown cause. I suspect there was a data corruption in the internal memory. This could potentially happen if the bike was turned off while still moving.

3. I had difficulty manufacturing the units. Because the 3 digits of the display are seperate components I would sometimes get epoxy leaking in between the digits and it would look bad.

I still have some units left which I plan to use to support the ~40 customers out there using the microSpeed Speedometer in cause they have issue.

I am working on resolving these issues and moving back into production again; however I don't know exactly when that will happen.

Stay tuned if your interested

Ironheads and old style distributor

If your wondering if the microTach will work on your older distributor style motorcycle. The answer is YES. But you need to request a special tachAdapter with more filtering than the standard tach adapter that ships.

Order the standard adapter direct from then send me an email at and request a distributor version of the Speedway Instruments tachAdapter.

Updated FAQ

So I seem to be doing a really poor job of keeping this blog updated regularly. I will try todo better. A couple things to update everyone about.

1. I updated the FAQ to include info about the microSpeed speedometer. Especially of interest is about the touchscreen interface.

2. Last month seemed like a really bad month for folks with standard version microTach and tachAdapters. I talked to a few guys having trouble with the tach jumping around (ie. from 10 - 25 at idle). So I modified the tachAdapters to do more filtering and sent them out new ones. That seemed todo the trick. So if anyone else has an issue with their microTach jumping around please let me know and I will send out a new tachAdapter.

3. All new shipments of tachAdapters will have increased filtering.

Thanks everyone for their feedback and support
