The software installed came with the truck and original engine, both the rebuilt engine and reman injectors were all ordered to match original equipment. Pensacola Fuel Injector says no trim codes needed.
This is not a little knock, when it knocks its huge, load, definetly more than just a trim code issue.
While driving yesterday, was running okay not knocking with sensor connected and out of engine, then engine compartment started getting hot, the sensor starting rising due to engine heat (air) once the temp guage reached 125 degrees the engine started knocking. I pulled over and poured cold water on sensor tip, temp went down, and the knocking stopped.

The engine came in a 2005 Freightliner M2 business Class.
We bought a rebuilt long block from Blackwater engines, their paperwork says....
SERIAL / ARRANGEMENT #KAL86820/258-9208
Our old engine plate says......

Okay, I have an update......purchased Cat cooling system temp sensor......plugged into harness (but not installed in block) started engine, started knocking cold, once engine warmed up knock went away???? Cooling gauge staying at 100 degrees (because not screwed in) runs and drives great warm with cooling sensor reading 100 degrees. Another words I think I tricked the computer, still don't know why she knocks and smokes when cooling sensor connected and reading normally???

I have a 2005 Freightliner M2 with a Cat C7 engine. Just replaced the long block with a rebuilt from Blackwater Engines. All rebuilt injectors from Pensicola.
Runs great until temp hits 125 degrees then its like a switch goes off and she starts knocking and pushing black smoke. Checked codes with computer, none. Used software to cut each cyclinder looking for a bad injector, still knocked, could not pinpoint a bad injector. Fuel pressure is 65 idle and over 85 under throttle. Replaced atmospheric pressure sensor, still knocking. Unplugged temp sensor, no knocking with no temp reading, then the temp gauge jumps to 200 degrees and then she starts knocking again?
