Default GReddy Turbo Question

Hi! I recently bought a 92 Miata with a Greddy Turbo kit installed and am trying to figure out exactly what is going on with it, the person I bought it from had almost no info on the setup so I have been looking around at the different components. My biggest question is about what the guy said was a boost controller, it is a black box with green leds that supposedly display boost, he also said that he lost the thing that plugged into it that was the adjuster for it, Iím wondering if any of you guys could give me a brand or any info on this, Iíll put pictures below. My biggest confusion is that I canít seem to find where the wires lead from the box, as the blow off valve looks to be only connected to the manifold via vacuum line. I was thinking fuel management, as there is not enough wires to be an ecu. However more investigation into the engine bay revealed a Vortech Fuel Management unit. Before this I have always had naturally aspirated cars, and mostly carbs so Iím just trying to piece some info together. Any info you could give me would be appreciated, thanks.

That's the Bipes box. It pulls timing, but has no boost reference. It looks at air temp and air flow meter, and modifies the incoming CAS signal before sending it to the ECU.

You don't plug anything into it, you flip the little switches on the back.

Wow...that brings back the memories. That was the first thing I bought when I got my greddy kit 14 years ago.

Yep I remember my Bipes ACU that I ran back in the day. Worked like a charm. Whenever I ran 110 octane I would just unplug it and hammer my GReddy @ 15psi. Made 227whp/217 ft/lb on the GReddy @ 15psi.
