MAP sensor
You need the MPXH6400A MAP sensor. It is possible to use any sensor, but unless you need to run more than 2.8 bar boost, save yourself the trouble, and run the MPXH6400A, as the provided basefiles are calibrated for it.
The following image shows the sensors on top of each other, incl. the pin numbering:
The pinouts are not 1:1, here is a table as to how they should be connected:
| Board | MPXH6400A |
| 1 | 2 |
| 2 | 4 |
| 3 | 3 |
Cut the old sensor off the rubber hose with an exacto knife, make sure to cut right past the nozzle, or you will need a new hose. Re-use the clip. Use a cable tie to secure the sensor in place.
