As far as GM Emulators /documents, from the few I know of, they were left overs from some of the GM College sponored design competitions. None of them that I know of had the software to use the system. There's a rumor that one of the AU firms got a full blown genuine setup, but that's just a rumor.
There are lots of guys that worked real hard off any list at trying to figure out the GM code.
Lingenfelter, and Callaway are two firms that got some back door GM Tech Support. There's a few other smaller player firms that got some rather interesting data, from GM. And again, there are some one man shops have done such great work, that it would be hard to tell their work from something that GM gave to them.

IIRC reading several mag articles in the early ninties about Bill Howell having worked at GM before going into business for himself. He was one of the only one's early on that I remember selling and/or tuning chips......mostly TBI since he would sell the retrofit kits that you could install on a "hot" motor. At that time I beleive the engine in the article was and early version ZZZ crate engine.

As I recall Howell was actually a suspension guy. Having contacts at work, is nice thou.
The ZZZ cal was a GM developement, from what I heard. They wanted an oem part number, and went to great lenghts to get the cal EPA/CARB firendly. You have to remember in those days, the EPA did their own emission testing.

The BUA hac. Where did it come from? I didn't see any names on it, just dates. The first one I find is 08/85 . Then it comments later than XXX portion was disassembled 02-05-95. Next date down is from 94. Looking at the bpw vs load table section, it was disassembled on 7-22-89. Was the dates a way to fudge up a GM doc, in order to cover things? If not, then it was a work in progress spanning from 89-95 (at least).

I've seen *comments* in EFI stuff, that were dated long before GM sold an EFI'd car. GM originally bought the 68HCxx as a package from Motorola, so the very, very first codes were all from *kennels* developed by motorola.

I found something very interesting in that article. THe single quote, " Besides, GM has let it be known they don't like people messing around inside their computers" . I really wish that I knew what they ment exactly.

Gm has been fighting the EPA since day one, about source code. There are lawyers that have spent their entire careers, and retired doing nothing but keeping GM's actual source code *private*. Originally, they (the EPA) mandated that the source code was to be public domained. But, GM, Ford, and all the oems consider it intellectual property, and will not publically domain any of it.

As a side note......
This has been a very imformative post for me, and I've come to appreciate the pioneers even more, especially since a few more have been named.
