I have a buddy that swapped a Detroit 14L egr for a 1999 MK 12.7L. It runs great, but the cruise only works at idle. It’s in a 2005 Western Star...
What’s weird is it only happens to mid nineties or earlier Cummins. I hooked to a ninety-nine model using the 6 pin and had no issues.
That’s what we’ve had issues with. I’m wondering if the older usb 1 would work, too.
It’s just the standard 6 pin gray plug. I wonder if there’s another adapter plug that I need? They have the older style powered adapter for...
Yes. He even tried hooking to the 6 pin right by the ecm. I was told that the newer firmware and drivers could be different on the usb link 2....
My friend has Cummins Insite and a Nexiq USB 2 adapter. He’s tried hooking to two older trucks with a 6 pin connector with no luck. One engine was...
I’m working on a M11 Celect Cummins in a toter home. It had intermittent issues and then just wouldn’t start. We believed it to be an ecm issue,...
Thank you for the replies. I'd like to hear from someone who runs a 701 turbo, too. He's wanting a non-wastegate turbo, so I think the 701 would...
I have a guy wanting to swap his factory Garrett on a 470hp Detroit 12.7L for a newer turbo. I'm thinking a k31 or a 171701 would work best for...
I gotcha. They will definitely smoke some and the ole turbo will sing. I thought you meant excessive smoke. It's not so much the smoke. It's only...
Those old B models would throw some smoke. It might need the pump freshened up, if it's excessive. This Detroit should smoke some and it looks...
We thought that to be a possibility. You're right about the settings, because there are quite a few with low nox settings. This one has been...
We checked everything and changed the mufflers out. They were stopped up. The temp is running right at 185 degrees now and the pyro is normal. The...
That might be the next route he takes. We're trying to exhaust all possibilities first. I think the radiator is okay. We're leaning towards...
He's not necessarily wanting it to smoke, but we know similar models smoke some. I mean not a drop, when I say no smoke. It almost feels held back...
I have a friend that has a 98 Peterbilt 379 with the factory original 6067BK60 12.7L Detroit set at 500hp. It runs great and had an in-frame done...
You're welcome. Hopefully that will fix it up. :cool:
It sounds like an issue with the cecu and the multiplex wiring system.
Have you asked Peterbilt to hook to it with the Paccar ESA and update it? I believe they can update them, and it might fix your issue.
In my opinion it's probably the crankshaft damper. We have a c15 that the driver thought had a driveline vibration. I suspected the damper, so I...
