Hi,
Is it possible to run 2 MAP sensors ?
I would like to use 2 oem sensors.
The one is currently being used for boost , after the aftercooler. I want to use the other one for boost before the aftercooler.
So that I can determine pressure drop through the aftercooler.
The sensor I want to use is OEM k20R sensor. A pinout would be great if this is possible please?

With the KPro4 you could use an analog input for the second MAP sensor. For the pinout see the factory manual. For the voltage conversion look at the settings in the MAP section of the calibration.

So I can connect a 2nd oem map sensor via analogue input and configure it ?
What do I then do with the one pin that meant to connect to a ecu pin on the map sensor?
Would that become the signal wire for analogue?

And is there a dedicated 5v and ground supply I should be using at the ecu for the sensor?

What KPro do you have?

Prc kpro 4

Wire the MAP Vcc to one of the ECU VCC pins. With the MAP GND to one of the ECU SG pins. Wire the MAP signal to one of the KPro4 analog inputs.

The analog input conversion is
Conversion=Custom
Type=pressure
Unit=mbar
Voltage 0 value -45
Voltage 5 value 1790

Wire the MAP Vss to one of the ECU VCC pins?
MAP Vss?
ECU vcc pins?

Find a diagram of the ECU pins. There are several vcc pins (vcc1, vcc2, vcc3) and several ground pins (sg1, sg2, sg3) to use.

Thank you. Much appreciated. Stay safe!
