Which diagram did you follow and did you splice the injector signal pick up wire from the ECM or from the fuel injector?

I like to check your wiring.

Do you have an updated wiring diagram for the HFS4-V3.1 for a 2008 Mazdaspeed 3?

Reason I ask is the HFS4-v3.1 manual calls for the red, green, and blue cables where the diagram on page 1 shows red, green, and yellow cables for the RJ48 connector.

I think I found the answer to my own question. Looks like page 20 (in the manual) shows the correct wire layout for DI applications which uses the yellow cable.

I did have a few questions on the jumper and solder settings though.

For the jumper settings, I believe all of the settings should be set to the default setting except the SET FAIL SAFE. I will be using an external trigger with a 5-12V input, so I believe this jumper should be set to FS1. Both CLP and FS0 jumpers can be removed. I will use the orange wire on the RJ48 connector and splice it with the external trigger of the boost control device.

For the solder settings, I plan to use the following settings:
AUX INPUT: default
IDC PRE-SCALER: x2.5 for DI
MAP SENSOR TYPE: 2.5 bar MAP sensor so I believe I need to solder link 2
FLOW SENSOR MAP: I'm using a single 0.9mm jet so I need to solder pads 1 & 2
AUX INPUT SELECT: default
AUX INPUT FAILSAFE: I believe this should be W?

Are these settings correct?
