On Nitrous/Aux 2, to use A20 (PCS) output to activate a nitrous relay, what needs to be done to Q31? It is a US P75 ECU. Tried it without changing anything on the board but it will not activate the relay.
Thanks in advance
Nothing should have to be done to the ecu for this to work.
This has been tested and is working in the software as it is supposed to. Without a calibration and datalog showing the problem it is impossible to determine what the problem may be.
