Mike, in a way I am sort of sorry I asked the question?
But...for what it is worth, I have a much better understanding of my Ignition, ECM and a couple other gizmo's.
Thanks.
I took my GM manual out and sat down for about an hour, and the points you make seem valid.
I don't think I will be trying to make anything happen inside. my Dist., though!!!
The list of "Plug & Play" items to be bought is longer than the time I have to tinker.

It takes me hours and hours and hours to read a very minor part of disassembled code, and even then sometimes I 'understand it wrong'. These guys impress me. The fact that he has no problem just diving in and modding an ECM that to date has no public definition file (meaning it CANNOT be tuned by commonly available software) puts him on the top of my 'super smart guy' list.
I'd love to pick his brain about some things, but I imagine they would probably all be covered under some past intellectual property agreement he signed with previous employers. heh oh well.

On the majority of GM ECMs, was the BIN's originally coded in C, or assembler?
I've heard rumors that they used some development environment in C which is why lots of code segments in various ECMs are the same, but other folks have said no it was written in assembler from day 1.

Could you answer this age old questions that has been speculation for years.
