[urq] EFI urq

As soon as I get my tax return back from the IRS that's what I'm doing
to my car.  Javad (the guy who's responsible for the system) knows a
hell of a lot about engines, particularly turbo-charged ones, and
particularly Audi inline-5 turbo-charged ones.  I got my hands on a
demo version of the ECU software, and I'm sold.

The idea of having all that space that is currently taken up by the
airbox, metering head, multitudinous hoses, frequency valve, etc. open
and free to work with (can we say SS tube header?  How about Garrett
T3/T4 turbo?) is enough for me, that I can get better performance, an
idle controller, intergrated spark (and eventually coil-pack ignition)
and use a wideband 02 sensor is just icing on the cake.  I fully
expect it to be the best money I've spent on the car so far.

A couple of guys with converted MCs have web pages up about the
conversion process, it really doesn't seem like it'll be that bad,
running all the wires looks like the most difficult part.  I do not
have the cash to go straight to coil packs, so I'll have to put a
distributor from a normally aspirated I5 in mine, the ECU needs a
5-window to do the timing correctly.  I'm figuring a weeks worth of
nights to get it all done.
