Wastegate Sol. question

[globalrebel]

Info . . .
Engine: 93 S13 SR20DET Blacktop
ECU: Blacktop ECU with Nistune Daughter Board

I am getting a VERY weird problem. After driving around for 10 - 20 minutes, the car will act fine and then all of a sudden start bogging stuttering and misfiring. I've connected to the ECU and think I've narrowed it down to the wastegate sol.

Everytime I press on the gas during this time, the wastegate sol turns and stays to ON. But, when the car is running fine, the wastegate sol stays OFF. I was wondering, where does it get this signal from? Our wastegates are controlled via vacuum so I don't understand what the WasteGate Sol would be for in Nissan DataScan.

Any help is GREATLY appreciated.

Normally, you have a info in the data display

but, I do not know the unit of measure
