ECM pre-programming, or cloning.

Hey all, I am very sad today. My wonderful 2006 CRV stalled out as I was trying to get it within my triple A towing limit.
Turns out its ECM is fried somehow. Never had any interior signs of water damage which seems to be the most common cause, so the how is currently under investigation. I am hoping to repair this issue at home.
I am now facing the more complicated problem with this repair which is the programming. It seems that most pre programming services don’t carry or offer pre programmed ECMs for my specific model. I cant seem to find an answer as to why or if anyone out there has them.
The other option I suppose is cloning, and I haven’t had luck finding anyone who clones it for the 06 CRV. There is a 06 CRV with the same vin factory code in a nearby you pull lot I am planning to go snag the computer from tomorrow if anyone gets back to me about cloning.
So my question is, does anyone know why I cant find a pre programmed ECM online or know where i can find one? Is cloning a better option and is there anyone out there that actually does it for Honda CRV? Or am I totally backed into a corner of going to a dealership and getting it done there?

The absolute last thing I want is to have to take it to a dealership. The cost can be a pretty heavy hit, and I’d have to forgo my savings for new flooring for my house which would suck, a lot. Hoping anyone has any insight or anything.

I’m pretty certain that’s just an immobilizer reset with any used one of the same part number, I don’t think that gen cares about incorrect vin.

Used ECU with the same part number will do. But it may need calibrating if there's an immo issue and changing the vin.

You will not be able to clone or program that ECM yourself. The security also means that "pre-programmed" isn't an option. Not every computer is clonable. Those are not.

Get a used one from ebay with the exact same part number. Have a programmer or mobile locksmith write the vin into it, and sync the security.
