I visited their website too. Kind of a strange website, especially for a business site.
I agree with atomarc. Click on the "Downloads" button using the link atomarc gave you and scroll through the list below to see if you can find what you are looking for.
If not, you can try typing in the Model number for your Tach at the "top" of the Downloads page and see if that works.
If all that fails, try emailing them at:
