1981 Buick ECM
I have a 1981 Buick Skylark V-6 with an ECM 1224810 CO and I got a replacement ECM 1224810 FX from a 1981 Omega 4 cylinder what do I need to watch for?

Re: 1981 Buick ECM
You can watch for it most likely not to work, 4 vs 6?

Re: 1981 Buick ECM
As far as I can tell both units are the same as it runs fine and is rich on idle and lean on high speed.

Re: 1981 Buick ECM
Could be, but at least it runs leaner at high speed than if you have no computer at all this should save fuel as far as timing I have no idea what it actually does.

Re: 1981 Buick ECM
If the ECM number is same, should be able to use it....just have to transfer the PROM, or in some cases, there may be a knock sensor "module" also to transfer......
