I'm interested in this as well as I will be doing the swap this winter. Where are you guys finding computers? Ebay? Junkyards?
I have found computers from both of those sources.
There is a small amount of risk, as you can't test a computer on ebay, or in a j/y for that matter.
Check with parts stores too, as sometimes the refubished units are quite resonably priced.
I paid $75 for an LA3 computer on ebay, but could have purchased a reman'd unit for ~ $100.
If it is in the budget, a new/reman'd computer is less risky.
I asked how the reman'd computers were of lower quality...
I doubt there is any difference at all.
The computer code won't be any different, nor will the hardware of the EEC.
I asked more as a challenge, as I don't see any way one EEC-IV can be inferior to another, with the same catch code.
