Purchased truck used not quite a year ago. We were told and given paperwork to confirm it had new head and machined the block.

The sticker on engine is serial # 79382815. Turns out, This was a complete engine swap prior to the engine work even being done. This engine belonged to a 2010 KW T660.

Our truck is an 09 KW T800. The engine serial number that matches our truck VIN (last 7 digits being J939104) is serial# 79295149.

When our truck is plugged into insight I think it might be picking up the T660 programming and not the programming for our original off the lot engine serial # 79295149 T800.

The Kenworth dealership is using the replaced engine serial # 79382815 but I’m not sure if this would use the same program and calibrations as the T800?

Please help.

Both of those engines ( 79295149 and 79382815) are compatible with each other 100%, after-treatment systems, programming, and all.

The question is .. Why are you still running a program that was meant for an out-dated dpf unit that is not longer made since 2015?. - Is this because of the after-garbage DPF installed?. .. and what does the company who make said garbage DPf say about what program you should be running?. The older program.. or the newer one?. -= Which standard did they go by for designing and making their garbage-can units?.

-= How much yow want to bet that the after-garbage company who made it cannot even answer those type of questions .. and likely don't even know about the changes to the DPF unit designs by cummins .. and at best, will only trying to tell you crap to dodge the subject and shut you up.
