Ddec6 turbo speed code

[trucklogger2]

Here’s a bit of an update...it’s a little slow going as the truck is quite a ways away. Test driving the truck after a bit the actuator froze on a partially closed position somewhere past 30% I’m guessing. So I pulled over opened the hood and could hear the turbo in a spooled up position and exhaust exiting the two big clamps on the turbo. Shut the engine off then keyed on and it was reset to normal. This seems to happen easier on the jake btw. The jake takes a while to spoil up too very slow.

Unilevers thought maybe the turbo was hanging up as it moved and was drawing too much voltage and froze at that point.

So after every little thing we do there is no improvement.
We have a new turbo and actuator, air filters,sensors,turbo outlet temp sensor wire was rubbing through and was black so we changed it, no change.
Turns out the dpf had several 2” holes drilled in it I set him to original shop to get it hollowed out so they drilled a 5” hole! They told him it would be too loud, but these guys gave him warranty on that turbo and threw on old actuator.!! Go get new actuator and have them check actuator wiring harness but they just said it’s the tune.
Mommaburt checked it out and gave that the thumbs up.

So now I’m suspecting mcm even though it’s eight months old(I’m thinking it’s a rebuilt which it could still be faulty) .
Somebody suggested it be set back to factory programming then retuned to mommaburts program.
Btw the dpf was like this for several years apparently.
The exhaust cooler was removed and plugged off , egr pipe removed and a plate installed at intake/valve. Note the exh manifold had cracked once maybe twice( hard to understand the owner sometimes) in the past after demandate. Maybe other long term damage?
Anyway we will clean out dpf completely this week
K thanks again TL2
