I purchased a 3 bar map and tip on modern performance and got a rescale done by dave. He was very helpful! But also idk why my tip is not reading ? I have a cel for throttle inlet pressure. After sending him my datalog he saying I have a fail tip sesnsor. Do I have a faulty one by chance ? I also took out that small white screw nipple off the tip sensor to see if that helps but not much. Any ideas what I can do to make it read ? Or should I return it and get a new one?
