LS XR4040
I just found out I'll need to replace the ECU on my XR4040. (420 hours) Has anyone else had to replace theirs? Has anyone had to replace it twice? At $3k, I don't feel like running into this problem every 3 years.
Secondly, is there any value to keeping the core/old unit and sending it out to be refurbished/reprogrammed? I've found this company among others that offers repairs, but I'm in over my head with this type of repair.
Any info/advice is appreciated. Wondering if this is a fluke or if it could have been prevented. Thanks!

Looks like they do work on New Holland. Might be worth a call and ask if they can repair your ECU. If they can't, you're only out a phone call.
They maybe an opportunity for all with tier 4 ECM, possibly ability to improve performance if they can modify software. Changing 4 hour burn off cycle to 15 hour window or more. You’re right if you own a core it would be worth the expense to see what they can do for it, regarding repair. Thanks for sharing the site.

Crazy high ECU prices that’s for sure ! Hopefully ECU prices will start getting lowered and it will never fail again
I am anxious to hear the results once it’s fixed

That's not encouraging about your ecu beer_hunter. I do believe that's the first I have learned of going gunny bag though.

It should not be that difficult, one would think, to refurbish an LS ecu. But, different things being 'locked under patent' might make it challenging.

The good part of this is LS is a base machine for NH and case/IH tractors in that hp range. So it may not be so hard to get a refurbished ecu.... Hopefully

YES! differently give them a call find
out the price of repair and if they can
reprogram the regen so it don't go
on so often like 50 hours or more
I wonder if the censors have something
to do with the regen going off so often

Based on tier 4 system earlier versions it was time based element to do regen. 4 hour cycle. Later models was more dependent on sensors or to reach the 50 hour regen. Not sure why EPA felt ag equipment needed tier 4 not like we run tractor every moment of the day. Would thought industrial equipment would have been the focus. Difficult to understand why the start level had to be 30 hp. Makes more sense on larger displacement motors that generate more particulate.

The Deutz 5080D don't have regen I
don't believe they have any pollution
control and its 75/80 hp

“No Maintenance” emissions: EPA compliant without SCR technology and without a diesel particulate filter (DPF)


comes with all 4 wheels with brakes

If you can't find any affordable repair options for your ECU and you decide to throw it in the trash, please PM me before doing so. I'll give you a little something for it.

dealer replaced mine under warranty at about 350 hours chasing a regen issue, it didn't fix it, but they did replace it.

Well........I also just found out that my XR4040 will need a new ECU. I have about 480 hours on mine. To make matters worse, the price has gone up to near $5000 after tax. 1/4 of the cost of the tractor. Told the dealer to sit on it while I recover from the gut punch. I'm not complaining so much about having to replace an ECU, but the cost is stupid.

Need to check out pc board houses a lot of places repair pc board’s industrial at fraction of the cost. Someone else on this sight had lead on repair house. All this board is doing is monitoring various sensors and providing close loop on emissions. Another thought would be tractor salvage have to believe these get rolled, on fire or some other unfortunate loss. Your right 5k usd is robbery at its finest. Might raise further concerns with your local farm bureau they have pushed for farmers on right to repair equipment. If this was insured by farm Bureau insurance you could have claimed repair for down time. They offer some repair replace on ag equipment used on farm through their policies. Farmers don’t always have liquid cash for down Tractor repairs especially in the spring time.

i think this is our ECU. Wonder how to get it programmed?
my tractor is in dealer for intermittent stalling which tech can’t replicate.

dealer should be able to program it with the stock flash

Wonder if they can program before it installed in tractor? I have 160 mile round trip to dealer and don’t have my own trailer.

An XR4040 uses a Shibaura engine I think. Regen on Shibaura engines was every 4 hours and LS did not make anything related to the engine, so wherever Shibaura got the ECU for them is anyone's guess. LS quit using Shibaura because of the problems with them. You can get an ECU for an LS engine for about $1200, but for a Shibaura over $3000. Don't know if anyone can refurbish it for you but good luck. Tier 4 A was phased in by starting with on-road engines only at first, then went to off road equipment over 175 HP, then went to 75 HP, and then with Tier 4 B down to 30 and above. Thank the tree huggers for pressuring the government to force this on us.

I've got the same problem with my 2015 XR 4040h. The fuel shutoff fuse keeps blowing. After a lot of diagnosis I decided to take the ECU apart, sure enough the board has a quarter size burn mark under the capacitors. Did you find a reasonable priced ECU replacement?

I have no way of knowing one way or the other about any vendors, and I don't live in Texas, but check that company's address, then start looking at reviews from Google Maps. In other words, do lots of research!
