I had not gotten around to fooling with the tune on the car until last night. Somehow I managed to make the speedometer read to max immediately, however I did find the worksheet for speedo CAL attached to the EEX file. So goin through the math's and everything I recalibrated the ECM and now it has no speed signal. Before it shot straight to 150MPH and hit fuel cut so I turned fuel cut off and got the kids to daycare before work this morning. Recal and now no response, only jacked up the rear end to check. I still have not ruled out a loose connection but I will post the values as well.
