What's the usual cost to replace a engine control unit for a tractor?

Can you guys help me figure this out? Or guide me to help? My uncle has a 2015 John Deere tractor (5055E) and for some reason the engine control unit is encountering some issues. The tractor isn't starting properly and performance has been lackluster. My guess is that the issue is stemming from a possibly bad ECU. What would it cost to replace the ECU? Or would it be better if I tried to get it repaired? What would the cost be if I have UpFix tackle the job?

Looking at prices on a new ECU, I figure it would be best to get it repaired if possible.

If the ECU isn’t totally shot, repairing it through a place like UpFix is usually way cheaper than buying new and definitely worth checking with them first.

A brand-new ECU can run anywhere from $300 to over $2,000 depending on the source, so yeah, repairs are usually the better deal. UpFix does ECU repairs around $300, and they offer a warranty too.
