I have connected the speedo output from the PCS controller to pin 71 of the pcm which is the VSS hi circuit. The result is the speedo barely moving off the stop despite trying a number of combinations of calibrations within the pcm and pcs controller. It is a terrible pain to try to tune wot shift points without a good speedo signal and besides the speedo really needs to work anyway. I was told there is a way to make the vehicle read the abs wheel speed instead of the transmission output shaft but tried changing a few of the drop boxes in the speedo tab of hp tuners without any luck. Can someone point me in the right direction? Thanks!!!
