Is the microTach+ tachometer hard to read at night? Or in bright sunlight?	The microTach tachometer LED display presents a readout that is easy on the eyes with large (0.45”) numerals. The output has been engineered with day and night riding in mind — not dark, not bright. The microTach tachometer display is about 4x larger than the analog alternative. All of this in a device that is about as big as the end of your thumb!

How hard is installing the microTach+ tachometer?	Installation is quick and easy on all Harleys and V-Twins. A variety of online installation instructions show how connecting only 3 wires (Ignition, Ground, and Signal) can be done on a variety of bikes. The microTach tachometer can be used with any single-fire or dual-fire ignition system and there is also an exclusive digital bus version specifically designed for the newer 2004+ Harley Davidson electronic ignition systems.

tachAdapter Questions and Answers

Question	Answer
What is the difference between Single-Fire and Dual-Fire tachAdapters?	The single-fire adapter has 2 wires to connect to 2 coil signals. The dual-fire only has only one. A single-fire adapter will work on either Single or Dual-fire ignition systems.
What if I don't know if my bike is Dual-fire or Single-Fire?	Use a Single-fire adapter. Hook only one wire to a coil signal. Test the tachometer. If the tachometer reads 1/2 the expected value, then you have a Single-fire system. Connect the other wire to the other coil signal. Otherwise you can leave the 2nd coil wire unconnected.

microSpeed™ Speedometer

Question	Answer
When will production restart?	I don't know for sure, but it will probably be end of year 2010. There is significiant cost in redesigning and custom parts and I am was not able to recover those costs from this design.
How do I configure the device	The instructions are online inside the product page or you can also watch the turtorial vidos.
TouchScreen isn't working	The touch interface is disabled while the bike is moving. If it does not respond when stopped, it sometimes helps to either turn the microSpeed off then on or move forward a bit so that the screen changes to speed display then back to Fuel trip display. Both of these actions will re-calibrate the touch screen. Also, check these other issues: 1. Don't hold the case and touch the screen (the case is touch sensitive) 2. Make sure the case is not contacting any other metal 3. See note about rain below
After install, I get numbers jumping around and I can not configure the microSpeed	This happens when you first connect the speedometer to the Harley digital bus and the Run/Stop switch is in the Run position. The Harley sends data on the data bus which the speedometer miss reads as speed pulses because it ships set in the Standard MPH mode. Turn the Run/Stop switch to Stop. Then configure the mode to Harley digital either KPH or MPH.
Does the touchscreen work with gloves?	Unfortunately, not. Just like an some touchscreen phones the microTach uses a capacitive sensing technology which requires the conductivity of your skin.
What happens with the touchscreen when it rains?	The touchscreen may not operate under heavy rain conditions due to excessive moisture on your hands and screen. However this is temporary and touch screen operation will restore once it and you have dried out. The speedometer will continue to operate normally during this time, however you may not be able to reset trip meters or view odometer.
