I haven't messed with GenIV stuff much, but if I remember correctly, they don't have a dedicated speedo output from the ECM, it was a CAN BUS signal to the instrument cluster. They do however have an 128k ABS output that I was thinking could be programmed to work with a speedometer. I am assuming this is what you have it hooked to? Do you have a local tuner that can look at it for you? It turned out nice, would be a shame not to be able to use it.
