I didn't want to make another thread, but wasn't successful in getting an answer so I figured I'll try this one..


I finally got the cover off my ecu to get the number down : 37820 PJO 666


I'm looking for another one on ebay, and I came across a 37820 PJO 665, will this still work? I couldn't find any info through google on these numbers, so any help would be greatly appreciated!

 

What exactly are you trying to do? All F-I 86-89 Accords are OBD0 so you *should* be able to swap ECU around the years.

 

Thanks! That's what I figured. But I wanted to make sure before buying an ECU offline.

The ecu in my car now isn't working right, so I've been trying to find another one to work with the stock, so hopefully with 665 will work. Thanks again for your help!
