The most popular sensors are usually
covered, being the L1H1 (Honda) and the LSU4 (Bosch). Both cheap(ish)
sensors. There are some low-budget and kit based controllers out there
from Tech Edge and the DIY-WB, that derived from the original EFI332 project,
the predecessor to the MegaSquirt.
Been reading about this.. kinda fancier with the datatlogging (but
that's cool, too) would be nice to have a plain vanilla meter for less
as well..Now, I wouldn't buy say a new VW or Honda and rip out the factory engine
control. As Eric pointed out to me, there's far more to it than just
injector opening times and head temperatures. If you had a more primitive
system like an L-Jet or early Motronic, EEC-IV, GM-ECM, it would be
worthwhile. The UMS will support sequential injection. The debate over
sequential rolls on whether it really buys you much. I'll try and post
info on these projects as they are announced and released by B&G. The PWC
(precision wideband controller) might be of interest to many here.
Apparently, the LSU4 sensors are available cheap from VW (~$50). The L1H1
sensors are a bit more expensive, as anything Honda does. I hear of
people
grabbing them out of junkyards for short money though.

From what I've read on the Tech Edge site.. the VW (Bosch LSU 0 258 007
057) sensor is now $29 from a place called 1stVWparts.com! Cheaper!!
