I've been digging through some boxes of stuff I've got (isn't it fun to remember that you've got three starters for your Z should you ever need 'em??) and I came across a couple of ECUs. They look different, one is black and one is aluminum... can't remember which cars they're out of. Is there a positive ID for them using the Bosch numbers? I know I wouldn't have kept them if they weren't out of good runners, but that doesn't narrow it down enough... any info you've got is much appreciated.
