Do Factory PROMs Include the Memcal?

It looks like I will have to special order a PROM from GM, which I had sort of planned to do initially, but I am not sure that they come with a memcal. I asked the parts rep if Calpak type PROMS came with the memcal, and he could not answer this question directly, but he did say that the "ones with the two chips only come with the PROM". I still do not understand this. It seems that if the PROM is soldered to the MEMCAL, the whole thing should be sold as a unit. I just don't want to have another incomplete setup after going through all this crap. Thanks.

The MAF/165 PROMs have the memcal with them also.

If your ecm uses a memcal, then everything is under a blue cover devise that is removeable, and everything is on that Board.

If it uses a lil black holder then there might be two lil chips to use. The larger the eprom (only), and the smaller one which is a netres.
