Computer upgrade for a 556 200 1992

posted by  someone claiming to be Dharvey on  Mon Dec 2 08:50 CST 2002 [RELATED]

Recently I reported replacing the 556 ECU in my 1992 with a used 561 that came out of a 1991 240. Works great so far, but I recalled some mention here that the 561 was trouble. I looked through the archives and found a couple of brief comments but no true skinny.

So, let me ask:

1. Is it true that the 561 has a bad reputation? If so, does it tend to croak suddenly, leaving one sitting on the Interstate?

2. Is the 951 a direct replacement--and if so, what cars/years would normally have a 951?

Thanks for any help you can provide.
