the biggest issue with core mem-cals is the knock filter module is part of the mem-cal assembly. dispite this, however, you have a couple of options.
I can do a part number search for knock sensors and find out what year(*) used the same knock sensor. Then you could use ANY mem-cal from that compatibilty list. This would make it easier to find a used mem-cal from a junkyard. The problem is I don't have the time to go out to the junk yard and get the mem-cals, but I can supply you with a list of what cars you can get them from so you can get it.
You can purchase a new mem-cal from GM. These usually cost $55.
I offer a service in which I can modify your stock mem-cal so you can switch out the EPROM chip without having to remove and send off the mem-cal for reprogramming. This means you would only have the downtime of that modification to the mem-cal. After I do the mod, I can send you individual chips that you can install yourself.
