k4nnon Posted February 8, 2023 Report Share Posted February 8, 2023 Another quick question about programming outputs. I have added an expansion harness to my PnP G4x for evo 9. I have all of the added inputs/outputs used except for an AN Temp4. Does this need to be used as a temp input or can this be repurposed as any input or output? Thanks for any input.

koracing Posted February 8, 2023 Report Share Posted February 8, 2023 This has a 1kOhm interal pullup to 5V so it is pretty much dedicated as a temp input as this pullup can not be disabled. Any other type of 5v analog signal in will possibly have skewed readings due to this pullup. k4nnon 1 Quote Link to comment Share on other sites More sharing options...

Adamw Posted February 8, 2023 Report Share Posted February 8, 2023 FYI, another workaround is you can move your IAT or ECT sensor to AN Temp 4 which will free up AN Temp 1 or 2. AN Temp 1 & 2 have switchable pull-up resistors so you can turn them off and use as a normal analog input for most functions. k4nnon 1 Quote Link to comment Share on other sites More sharing options...
