Mikel58 Posted March 30, 2022 Report Share Posted March 30, 2022 I'm setting up my g4x in my s2000 and the map reading is backwards. Anyone ran into this issue? Quote Link to comment Share on other sites More sharing options...
Vaughan Posted March 30, 2022 Report Share Posted March 30, 2022 As in higher pressure when idling than when off? what MAP sensor are you using? Plugin ECU? Quote Link to comment Share on other sites More sharing options...

I'm using my factory map sensor. Calibration set to honda 92-99.

When the car is off the map psi is 14.6. when on it's fluctuating around 4-5 Quote Link to comment Share on other sites More sharing options...

MAP is absolute pressure so 0 is total vacuum and 100kPa/14.5psi is atmospheric. MGP is gauge pressure so less than 0 is vacuum and greater than 0 is boost (MGP = MAP - BAP).

I'll try to get it setup today Quote Link to comment Share on other sites More sharing options...
