I'm looking into upgrading my throttle body. I haven't found much info on what I'm asking, hopefully I can find something here. I know that the signal is 32 bit digital for the ECU but what I need to know specifically is if the signal from the throttle body is analog or digital? Is it a standard 5V TPS signal sent to a PCM to be digitized for the ECU or is it digitized at the TPS?
