2) not sure where to get the map signal from sense the sensor is internal in ECU.
3)waste gate fail safe for electronic boost control. to go to gate pressure on meth turning off or begin interrupted. i have a gizmo ms-ibc uses mac valve. im reading using the brown and white wires on gray harness to just splice one of the wires going to the mac valve?

1. It appeared the sensor is has an 0-5V output (pin 4):

2. Cut the pulsed wire from the MS to the MAC.

but how will the controller react since my map sensor is 4 bar. should i still use the 3.5 bar map in the hfs4?
