    Yep, I plan to switch over to aftermarket EFI one of these days. The
SEFI8LO is currently on the top of the list (well, the only one on the
list, actually) but I'm waiting to see some details about Accel's Gen 7.0
DFI, which is supposed to be released very very soon. From what I've read
so far, it will do the same stuff as the SEFI8LO (including wide band O2
sensor and WOT closed loop) but will cost about half as much
($1800). Sounds too good to be true. With Accel's greater market share
and what with economies of scale and such, it just might happen
though. I'm just sitting back and waiting for the magazine reviews, or any
info on the Accel web site. (GM High Tech Performance said they'd print a
review as soon as its released.)

   Yeah, that DIY EFI list is something else! I subscribe to it, but
haven't had a lot of time to read it lately (I hope it will be able to go
back to realtime mode soon, the digest is a bit of a pain to read.) :-(
If anyone ever gets to thinking that they're pretty hot stuff with
electronics and/or automobiles, hanging out there for a few days can be
really humbling! :-) I want to try building my own EFI system some day,
maybe something I can use on my Suzuki Intruder 1400 or my 447cc
ultralight, but I'm gonna start on safe, cheap stuff like lawnmower engines
and go-karts. (I think it'd be pretty cool to have an EFI go-kart, or an
EFI weed-whacker, just for the heck of it) :-)

     I wish I had some background in EE. I've got CS coming out the wazoo,
but it seems like the EE guys have all the fun. :-) I just got into
electronics and microcontrollers recently, so I'm trying to learn this
stuff on my own. :-(
