Qsx15 turbo wastegate control valve?

[Moffat]

Yes I removed exhaust and tested. Also tested complete intake system. And I’ve checked all over on quickserve. Although I’m not an expert on it I’ve gone through most if not the whole service manual on the enginei have tried to follow the troubleshooting to the best of my ability. I just can’t find any additional information on that valve whether it controls the fueling or wastegate or what it’s actually doing. I’m thinking it’s not a part that was commonly used so they’re isn’t a whole pile of information on it. Only an ohm test for the electrical side of the valve which isn’t failing. That’s also the reason I’d like to just make this tractor identical to my others if it’s only the turbo and a tune away. It would make diagnosing a power issue more accurate when I could hop between two supposed identical tractors. When Cummins was out they did injector cutout test but it just tested front 3 cyl vs back 3 cyl. No bubble test but it idles smooth and doesn’t smoke mores than it should. I’d like to have a way to acces the information or get somebody who knows what they are actually looking at to watch the computer. It would make my life a lot easier. I’ve done a hours of reading but I can only dig so deep without any computer software and I don’t want to screw something up with nobody showing me what I’m reading in the ecm. Local Cummins closed down this year so they aren’t an option anymore either
