electronic speedo conversion

[destinbeachman]

How many of you guys have converted to an electronic speedo and which one did you use?I'm looking at one of the Autometer speedos and would be using their Hall-effect sending unit and am wondering how easy it is gonna be to reprogram for tire and/or gear changes. By the way,Dale Jr. is winning!

Thanks for the link,but it's not working for some reason.I already tried to take a look at it from the Summit website.It should be fairly easy but I like to peek at the instructions anyway just to see if there is something oddball.My speedo hasn't worked in years and I'm finally getting around to updating everything.It'll be nice to stop checking my tach and trying to figure it out.
