No shit?!?!   My V8 S-10 gets 16mpg/18mpg, which is comparable to the
2.8L that was in there, so I thought I was doing pretty well.  You must
be using a shorter Canadian mile or something!

There is promedit, which is a generic PROM editor program.  It's driven
by a file that describes how tables are laid out in a particular PROM
image.  So if you can figure out the locations, or know someone who has,
you can use promedit to edit your 165 image.

ECMGUY has a hacked 165 listing on his WWW page, so you could sit down
with that and make a .ecu file if someone hasn't already.  There's
another program called winbin (windows only) that is a graphical editor,
similar in concept to promedit and driven by the same .ecu file.

You have to have a chip programmer.  Check out www.needhams.com for some
inexpensive ones ($150-$200).  A programmer can read a chip and create a
.bin file, and then after you edit it it can program the new bin back
into the EPROM.  You'll also need a UV eraser to erase the chip after
you read it and before you write it.  digikey (www.digikey.com) sells
one for $50 called Datarase II (get the $50 one with the timer, not the
$40 one without).
