Hello I'm in the middle of an engine swap on a toyota pickup using a 3.8 MFI out of a 85' Buick Century. The problem is I lost the ecm, I'm hoping it just ended up with the rest of my ecms, but the only possible one is missing the tag that had the service number and broadcast code on it,I pulled the cover off of it and the prom has the broadcast code ATNB.I have searched all over the net and can't find that code. If anybody knows what that code is from and what service number ecm it should be in, or where to find this information it would be greatly appreciated. Thanks

 

That's the one. A 1226461 ECM from an '85 Century, Ciera, or Cutlass.

I really appreciate the prompt response, glad thats the one. I just moved a couple months ago so now all my stuff is mixed up and not organized yet , I was starting to think it got left behind. Thanks again
