FYI, I do have a modification to the 7730 ecms that adds a switchable
Dallas battery backed up ram chip (switchable between eprom and
nvram... all within the original case). I'm working on better software
now (diacom/table editor functions within the ROOT C++ development
framework). The ecm data are alterable through the aldl. I'll get a
picture up on the web as soon as I can borrow a digital camera.
