Update

I haven't updated in a while, so I thought I would post some of the latest developments. I have PCB's now for the tach adapter and hope to build have them on a bike tomorrow. After at least a week of riding then I will start shipping. The adapters are just noise filters to make the signal acceptable to the microTach+ Tachometer. The actual microTach+ model is the same as the one for 1999-2004 Twin Cams. Also, I have started on the All-in-one Speedometer. This is going to follow the same Small is Better approach and expect it to be smaller than 2" x 1" But still have all the features you need like Speed, odometer, trip meter, and indicators. I will try to keep you posted on developments.

Tach adapters delayed

Due to some difficulties during testing the tach adapters are being redesigned. This will result in delay of the coil take off models which would support all bikes Big Twin's older than 1999 and sportsters older than 2004. I am sorry for the delay.

Chrome is Here

Due to higher cost of finishing in chrome the cost of chrome finished is increased.

Mechanical Drawing and update

Now I have tinted lens over LED display. Provides better contrast and looks better. Chrome is ordered, and so are electronics with 36" leads. Delivery is expected within 3-4 weeks. I will be at Republic of Texas Rally May 31-June 2.

Mechanical drawing of case is available

Anodized Case

New improved Case! In about 2-3 weeks I will stop selling the molded microTach and start shipping an improved version which has an aluminum case. This will be available as black anodized or Chrome plated. Here are some pictures of raw prototypes. Finish quality will be much better in final product, but as you can see the overall look will be more uniform and smooth. The size is actually slightly smaller than original.

New Aluminum Cases!

I wasn't satisfied with the molded microTach. So I finally did a 3D case design and got it machined by
REF Machining.

Diag Port Connector

Today I tested the microTach on a Softail Deluxe. It worked great. Therefore it is confirmed that the microTach will work on all TwinCam's with the J1850 serial bus. Which are all models 2004 or later. Also, all HD 2004 and later use the DT-04 connector, so if you want to use as a temporary install for diagnotics or tuning. Just add the connector and plug into diag port. There is a link on product page to a vendor.
