G4+ supra 3bar MAP calibration


Recommended Posts

Hi im trying to calibrate my MAP sensor which is a link 3 bar using stock MAP wiring. Ive selected the link 3 bar sensor from the drop down menu but when trying to calibrate it i have a fault - MAP Sensor Calibration command failed: Current map <5kpa or > 5kpa of baro reading. It says its using AN Volt 1 for MAP sensor. Can anyone tell some things to check or change in order to get this to calibrate. Thanks. Rob.

To give us some clues what the problem is, go to AN Volt 1 settings, change the error low to 0.0V and the error high to 5.0V.  With engine not running, open up runtimes screen (F12) and have a look at the analog tab as shown below. Tell us what voltage is showing on AN 1.  With the 3 bar sensor it should be about 1.62V at 100Kpa.

The voltage you are seeing there matches the stock Supra MAP sensor.  Set MAP sensor type to "ST185" and the calibration will work.

What made you think you have a 3Bar link sensor?  Or maybe it has been wired to a different input, and you still have the stock one in place at the same time?
