Ages ago, probably all the way back in oh, 1993 or so (?) I stumbled across
a mailing list calling itself DIY-EFI, and that's what those guys were all
about Much of it *way* over my head, and I've completely lost track of it,
but it did make for some fascinating reading for a while there. Roy J. Tellason wrote:

If you're talking about eprom emulators, "back in the day" I used to
use a device called a "PROMICE".
It was wonderful. I did a few different boot proms with one. Very handy.
It was made by (I think) Grammer Engine. Try www.promice.com. But
gosh, they do seem more expensive now that I remember...
I looked on ebay and didn't find one, sadly; I did find, however an
"ostrich 2.0" USB eprom emulator which looks nice. www.moates.net
Apparently there is a large community of people out there hacking engine
ECU's. who knew? :-)
