Error Calibrating MAP Sensor

Yesterday I tried calibrating the MAP sensor and I'm getting the message "MAP Sensor Calibration command failed: Current MAP 5kPa of baro reading.

MAP and BAP readings:

BAP = 98.6 kPa.

MAP = 89 kPa.

Ive been told by the owner that the ECU was originally sent back due to a faulty MAP sensor and Link had replaced it with a 7 bar sensor. When the calibration was attempted, the hose was disconnected to the MAP sensor and blanked off at the engine side.

Car: Mitsubishi Evo 6.

Link G4+.

So the calibration isn't correct the the MAP and BAP are not the same with the engine not running (or the MAP sensor not connected to the manifold, so it measures barometric pressure). Seems like you need to try another MAP sensor type to match what you actually have. Or you have a wiring issue.

That's correct. The calibration had not been set up correctly by the previous mapper so I'm attempting to recalibrate the MAP sensor and start again.

Following the guide, I disconnected the vacuum hose from the inlet manifold so the MAP sensor should read the same as the BAP sensor, but it does not.

The MAP sensor is attached to the Link board and I have been told that, after the board went back to Link, they installed a 7 bar MAP sensor. This was selected when calibrating, but no joy. I tried other types such as the Link 4 Bar, but still no joy.

You might want to look at this thread on the Link Support Forum. It talks about using custom calibrations for MAP sensors, etc:

Thanks David. That's handy to know. I believe the 7bar setting is for Link sensors so it should be the correct preset, but I guess I could try the custom calibration route if I can get the calibration settings.
