hi, thinking of getting the speedo /tacho , hd70900071.
one didgit is different because it is in kph, not mph.
i have a thundermax a/t, will it be compatable?
anyone?
thankyou, grumpy.

 

You will have no problem with compatibility. All HD speedos run the same way.Even aftermarket units have no issues with the TMax. I run a Dakota Digital with my TMax and it was a simple hookup.

 

I also have the Dakota digital with the t-max. I really like the Dakota unit, less money than the HD unit and it does more.

 

I'd really like to know if you get the speedo and it works with the t-max. Let me know.

 

I think someone here commented about contacting TM and was told that their ecm does not retain mileage like the oem one does so there will be nothing to transfer.
