ECU don't usually fail by themselves. Cummins injector wiring or even an injector failure can cause ECU overheating and failure. Here is a list of the most common reasons ECUs fail.

So, having an extra ECU with you may save the day or may only remedy the situation for a short time.

Ive got 35k miles on my replacement unit, guess it could go out any time soon then

So this has been in the back of my mind since I purchased my rebuilt ECM. Lifetime warranty. Like 950K miles recorded on it. Its not rebuilt but reflashed. Very few failure history, but without a working ECM you have a expensive paperweight.
I offen consider getting a "new" spare knowing that it would be less than the cost of a tow. Would also carry with me in the coach in a shipping box. Im guessing if I was to purchase one I would never need it! But would have with me to overnight to someone who did. It can take days to get one and longer to get it programmed to your coach. I am my own worst enemy. Good warranties are great till you need the product
Programmed Control Module ECM ECU 3408501 Cummins Engine Parts QSM11.... I contacted them and they said can be programmed to our coach.  Was $1190? This is made by Cummins of China. Anyones guess as to build quality

If you got that, which I'd be hesitant to being from China, I'd want to swap it, take it for a spin around the block and if all is good, start a trip asap to ensure everything works. You'd have your backup as a spare should something go wrong. If anything does not work as it should, you have 60 days to return it.

Is there a junkyard for these? I wouldn't mine buying one as well and having it reflashed/reprogrammed.

You got me looking Scott.... My 2000 is a different part # than your 2001, I have Cummins ISC ECM 3944105 – Diesel ECM. 

I don't know anything about this place, but the price seems fair for it being guaranteed tested, programmed and a lifetime warranty. Or send in yours for a lower price. I did price a new one for mine, it was just under 3 coach bucks. Ouch.

Here is the part # you supplied. Cummins ISM ECM 3408501 – Diesel ECM

Anyone used this place before? They're in Grand Prairie, TX.

Does anyone know someone who has successfully replaced their king control with an air throttle.  I lost mine in 2019 on a trip to Florida. I have a 1998 U270  with 8.3 Cummins and an MD3060R transmission. A trucking company in St. AUGUSTINE Fl. Installed an air throttle I purchased out of California. Total price $4500.00. I asked about the fact that the transmission was electronically controlled and the engine was mechanically controlled.  The said don't worry the tranny will figure it out. They were wrong obviously and shortly after I arrived at Space Coast I figured that out and installed a tips. It sifted better but still not right. When returned to Maryland had Johnson and Tower reset the counts and it was shifting as it sould however it would stick in first gear occasionally and would not release unless you shut down the engine and restart. Returning from Forida in 2020 we lost the transmission.(hole in side of the case). $9000.00 later with a replacment rebuilt transmission we were back on the road but transmision was shifting all over the place. Got it back to Annapolis and had local Allison dealer reset the parameters and was told to drive it locally in stop and go traffic. Having done this for an hour or so it figured out appropriate shift points. However it still gets stuck in first gear after initial start  and is an enigma to all so far. I'm sorry for such a lengthy description of my woes. Does anyone have a idea what's causing this condition?  I've talked with John Kopaluk and he said the codes I'm throwing don't suggest he can help me. I've taken off the connectors at the pad and ECM, cleaned and replaced them. No change. Ive also replaced the outspeed sensor which is the origin of most of my codes.  HELP
