Cummins ISX CM871 Technical discussion

Great thread spent idle time this morning reading it. Hats off, good job Rawze.

Awesome work!

 

Thank you for the videos. I watched them all. That engine is similar to mine. It is an ISX CM870 so it's a little different. I'm going to try and clean it in the next few days. I'll let you know how it turns out.

 

I'm going to do mine soon too, but I'm going to make the bossman a deal.

He gives up about $400 in parts, I'll supply the labor, and anything over 5.5 mpgs we'll split.

Engine is missing, idles rough, slow to rev, and getting 4.6 mpgs. I'll run this by him when I get back into town

 

Hi Rawze i have a new problem, every once in a while I'll get a CEL that displays Turbo Actuator but then the turbo does a slight whistling sound and the CEL goes away so i have a question is there a tune-up process for the turbo sort of like the one for the EGR system?

 

i have, a couple of times.

 

It's just so nice not having my truck idle like a dozen hair dryers.

 

Its my Chrome browser failing once in a while. Thanks.

 

That is exactly what I asked Rawze. I told him there is no way an APU make that much difference. He said when he runs his APU at night he loses 2 miles per gallon. He told me to try shutting down my APU for a few days and see what happens. He was right. APU need to be tuned as well. What I know for sure is that when I shut off my APU I got the highest miles per gallon I have ever had in this truck.
