It looks good, much more 0 values now and not just random. Parts that was FF (unused) now looks like ran...

I agree, there are very few cars with the CEMB unit left. We do not take these cars for diagnostics because of their age. But I was interested in reverse engineering and the lack of a tool for this block, so I decided to try my hand at it.
