Looking for a speedometer calibration unit for my 98 Fatboy. My speedo is off by 28%. when doing 50 on the speedo, I'm actually doing 70 as confirmed by my wife's car...I know Dakota Digital makes one but it is a bit pricey. D-gyver once told me of one that went for $36 but I cant seem to locate it or him. In fact i can't find any other unit. I know they are out there i'm just having a hard time locating them. Some help would be greatly appreciated. Thanx.....

 

I have the Dakota Digital one on my Dyna....It works very well and was super easy to install and program.

Worth the money!
