Real world... X15, MX13, d13, or DD15???

I’ve only used Motive and haven’t had any issues. I can’t remember what it’s called but there’s another port to plug into under the dash instead of using the diagnostic port. I imagine it’s plugging into the diagnostic port that can cause issues.

 

Since 2019 the RP1226 is the standard connector to interface with third-party devices. We had so many J1939 faults caused by poor installation of devices splicing into the datalink in random places. lol

 

For local use. It's totally avoidable.

 

I know this post is months old and you probably already made your decision, but I figured I would add my. 02. I have a 2018 Cummins X15 in my truck with 450hp/1750tq hooked up to an Eaton 10sp auto. To put it mildly, this truck is the reason I will NEVER buy another Cummins motor. I bought the truck in z June, 21 with 389k on it. I'm now at 523k miles. In that time, I have replaced the turbo twice, replaced the DPF, replaced the DOC, replaced nox sensors three times, new cylinder head, rebuilt cylinder 5, replaced the #5 injector, replaced the water pump, replaced the fuel pump, replaced the ECM, had two power steering leaks (one major, one minor), three separate coolant leaks, replaced the air dryer, replaced the fan clutch, replaced the throttle intake valve, replaced the fuel rail high pressure sensor, and I'm currently tracking down an electrical issue that's draining my batteries.

In short, I've dumped at least 100,000 in repairs into this truck in under 3 years. A Cummins will bankrupt you faster than any other engine on the market.

 

After 22 years. The mx motor so far is the only motor I've driven that just keeps on trucking. Almost a year now. And it has 650k.

The truck has had its quirks. But most of it I attribute to the eld that used to be plugged in. And bad batteries. It's not seeing the shop much these days. Other then a couple of flex pipes because it always needed a regen.

 

There is a reason Cummins is Nick named cumapart. I wouldn't own one after the n14, was actually looking for an n14 when I got my current truck with the c15 but couldn't find one that was reasonably priced.

 

That is crazy $100,000 on 134000 miles is practically 75 cents a mile on maintenance not to mention covering or losing loads .hopefully it doesn’t put you out of business. Hopefully your luck changes with the red beast.
