Is there anyone who knows the wiring for the d-jetro map sensor and iat sensor for a series 2 rb25?

Ive been trying to translate my japanese instructions with little success.. I also tried searching..

Ok, so I finally got Apexi on the phone and for the r33 gtst, the iat red wire goes to pin 57 (exhaust temp input) and brown goes to pin 30 (tps ground). Now my IAT is reading correctly. For future reference, pin 57 did not have a wire in the ecu connector, I had to add in a pin and wire supplied with the Mazda IAT sensor kit.

The boost sensor on the d-jetro model plugs straight into the side of the ECU as I imagined it did, but for verification purposes - this is indeed where it connects.

However

My map sensor is still reading incorrectly, so I will have to troubleshoot that.. Its reading -44 mmhg. Which is like -.8psi. :wtf2:

If anyone has map sensor experience, any input is appreciated.
