I know about megasquirt, but had "set it aside" thinking that I
could use a stock GM ECM box and avoid the hacking. I even own a
dev kit and ICE for that Motorola chip! I was hoping I could find
an appropriate ECM for say a 4.3L v6, with distrib, bolt on to my
4.2L and drive. I've avoided software hackery in all my cars so
far!  But it's really hard to wade through all the raw info and
increasingly looking like hackery is needed anyways to "tune" the
GM boxes.

I'd forgotten this -- found your website. You should brag about it
more :-)

Let me mull this over until next payday :-)
