I'm trying to heed Mr. Roe's warning to acquire spare parts for our 79 Seville. I have a friend with a 76 Seville that he's in the process of dropping a LS*/4L60E from a late-model Camaro into. So, the ECU out of this Seville will be available. I figure it if till work, I'll buy it. It is a friend of mine, so I don't want to cheap out on him, but don't want to pay top dollar, either. I've done some searching, but still have some questions:
1. It looks like the ECU from the 76 might work, but what do I need to look for? Any codes/part numbers? What should I avoid?
2. What's the 'going' price for a used ECU? I assume it was working, as the car ran perfectly to the friend's shop. This particular car has something like 30K miles on it. The interior still has that 'new leather' smell.
Thanks for any help.
At most $200. At most if you are generous.
Maybe $150
Here are the codes I got from Bruce. Which one is that ECU?
E = Eldorado
K = Seville
C = full size rear wheel drive
Fed = 49 state application
Cal = California application
500 = 76 Cad engine
425 = 77-79 Cad engine
350 = 76-80 Olds engine
Orig = original part
remf = remanufactured or replacement part

I haven't seen the ECU yet. It hasn't been removed from the car. And I have no clue where the car came from. But as I understand it, if either is a California car, but not both, they won't work? I'm pretty sure the 79 is a Fed. I don't remember seeing an O2 sensor on the exhaust, but I haven't spent any time specifically looking for it, either.
I think the open loop ECU's wont work with your car. The regular California one might. Maybe if it works, offer him $150. If it doesnt, give him $75 and keep it until someone needs it?
Well, it's supposedly off a 76, and none are listed in the above list as 'open loop', unless they all are, and there's no need to differentiate. Thank you.
I'm sure a ECU 76 will run well enough to get your car home in case of
an ECU failure. I also think there is very little difference between CA
and FED ECUs, some have an EGR output. An open loop ECU ought to
run a (very rare) car originally built with an OX sensor; you just lose
that feature. However, I haven't tried driving all the combinations,
to see if a difference is detectable. The primary thing is, don't use an
ECU from a different size engine. Bruce Roe
Bruce,
Thanks. That sounds good. It's out of a Seville, so we should be good to go. An added plus is it's a low-mileage car, and appears to have been always stored indoors. I've worked a deal where I'll be getting my friend a rear Quickor sway bar and we'll trade for that and some cash. He says he also has some of the engine sensors and a working right-side mirror assembly he'll throw into the pile.
I'll open the compartment to my ECU just to grab the codes off of it so I know what I have. Hopefully, that info is easy to access without having to pull the ECU out of the car.
Its on a sticker. I think if you look at the ECU from the front, it is on the passenger side. Driver side is where the cables go in.
