The system can be configurated to read absolute (0-5V), 2-bar and 3-bar MAP sensor. You can use the 0-5V input for any load related sensors such as mass air, throttle angle etc.

Choose your MAP sensor to match your boost pressure. Up to 15 psi for a 2-bar and upto 30psi for a 3-bar sensor.

On eof the more popular map sensor is made by GM, availoable in 1, 2 3-bar range. The HFS-4 has 0V and 5V output to power it. Requires a custom cable, not costly.
