Emu pro with map-400 voltage under threshold

Hello,

i have switched from the OEM sensor of my car to the map-400 sensor. When the car is now in overrun and pulls a lot of vacuum on deceleration the sensor has under 0.2 Volts and will cause problems.

Am I missing something in the configuration / calibration of the sensor?

valid voltage min, set lower voltage, it triggers failsafe
