Hi all I have a problem I hope some one can help I had the cobra on the dyno and it came up with a fault which said the speed sensor to the ecu (standard ecu series 1 au xr8 5lt) was not working, checked my wiring and found that the sensor wire was being used for the speedo and ther was no wire on pin 58 on the ecu, if I rewire to ecu the engine will run up to full revs but I have no speedo if I connect to both the same thing happens the only way I can get speedo to work is only wiring it direct to sensor but engine won't rev out can someone help.
