[QUOTE="shurur, post: 16590130, member: 113850"] The speedcal adjusts for a change in the gear ratio. It is used instead of changing it in the ecu. Look it up. The speedcal has been around for a while, although it is not made anymore. It was the go to device for many years. And there are folks still looking to buy them used. I just want to eliminate it from the equation as I troubleshoot this thing. If I remove the speedcal and the speedometer works (yes the speedo will not be working accurately fir my 3.73..but will work and not bounce or float or whatever it is doing now), then I will know the problem is not the cluster. Ground is good btw. I am looking for a wire diagram for the speedcal install, as a picture paints (replaces) a lousy thousand word set of install instructions. I am also so happy for you that you could afford an SCT tuner and a procharger...good for you. [/QUOTE]
