Unknown voltage at analog input

Post by Supra Sundays » Mon Jul 20, 2015 12:48 am

Hey guys quick question.

Im getting a reading of 1.144 volts at analog input #2 with nothing attached. Ive tried disabling the input and grounding it and the voltage remains the same. Also if I put 5 volts to the input nothing changes either. Im using input 2 to activate launch control while input 1 is my factory map sensor, 3 is my wideband and 4 is the built in map sensor. How can I fix input 2 to use as a switch?
