Simon Posted December 13, 2016 Report Share Posted December 13, 2016 It is a 4bar sensor (3 bar of boost) Quote Link to comment Share on other sites More sharing options...
Grant Baker Posted January 21, 2017 Report Share Posted January 21, 2017 Out of interest, which analogue input is assigned to the internal MAP sensor? Quote Link to comment Share on other sites More sharing options...
Scott Posted January 23, 2017 Report Share Posted January 23, 2017 On the EVO 9 plug-in ECU AN Volt 1 is used for MAP. The ECU has a jumper that allows either the onboard 4 bar MAP sensor, or the factor MAP sensor to be used.Scott Quote Link to comment Share on other sites More sharing options...
Grant Baker Posted January 23, 2017 Report Share Posted January 23, 2017 How about the EVO 4-8? Quote Link to comment Share on other sites More sharing options...
Simon Posted January 23, 2017 Report Share Posted January 23, 2017 EVO 4-8 is also on AN Volt 1 but there is no jumper. It is also a 4 bar sensor. Quote Link to comment Share on other sites More sharing options...
Grant Baker Posted January 24, 2017 Report Share Posted January 24, 2017 Interesting. On my G4 plug in (EVO 4-8) I had AN Volt 1 as Oil pressure and AN Volt 2 as MAP sensor.I've upgraded to the G4+ and MAP is showing correctly (I have kept the external sensor). What is AN Volt 1 now showing me then?I have done no wiring changes. Quote Link to comment Share on other sites More sharing options...
Simon Posted January 24, 2017 Report Share Posted January 24, 2017 (edited) AN Volt 2 is wired through to the factory AFM signal. So assuming you are using this wiring to bring the MAP back to the ECU which is fine.AN Volt 1 on the very first boards was wired to pin 73 (bottom board versions 1.1 and 1.2) on later board revisions 1.3 on this changed to AN volt 8I would suspect you are seeing a map reading from onboard sensor as the oil pressure.

Grant Baker Posted January 25, 2017 Report Share Posted January 25, 2017 So we need to move that pin then to AN Volt 8? Quote Link to comment Share on other sites More sharing options...
Scott Posted January 25, 2017 Report Share Posted January 25, 2017 Hi Grant,An Volt 1 (Internal MAP sensor) should be turned off.An Volt 2 (pin 90) should be set to MAP and configured to suit your external MAP sensorAn Volt 8 (pin 73) should be set to Oil Pressure.Scott Quote Link to comment Share on other sites More sharing options...
Grant Baker Posted January 25, 2017 Report Share Posted January 25, 2017 Sorry - I misunderstood what you said.So on the G4 pin 73 was AN Volt 1.On G4+ it is AN Volt 8.Thank you. Quote Link to comment Share on other sites More sharing options...
Scott Posted January 26, 2017 Report Share Posted January 26, 2017 Hi Grant, yes that is mostly correct.On the G4 ECUs and early G4+ ECUs (basically any that used bottom board V1.1 or 1.2) pin 73 is An Volt 1.On the later G4+ ECU (any bottom board that is V1.3 or V1.4) pin 73 is An Volt 8.Scott Quote Link to comment Share on other sites More sharing options...
