Todd and others,

I was able to download the cal from the Marc Randolph chip currently in my 92 Z. The ECM is service #16163993. The Mask ID in that bin is set as $AA. When I look at the stock AYWT bin, the MASK ID is $D0. I'm assuming since the 3993 was used for multiple years that it can handle mutiple masks. So I should be able to replace or transfer this bin over to a $D0 mask if I wanted to. Correct? What year is the $AA mask for? When I look for ZR def files on TP or Moates, I find an $AFA mask. Are these two the same? When I do a compare, it appears they are.
