was re: audi 90q gurus, now a strange discovery

[alan pritchard]

well in my previous post i said how i had a kv bottom mated to a ng
head/manifold etc.  I then went on to check it had an ignition ecu, i looked
under the drivers "shelf", (RHD) and couldn't find one...................
I found two, taped together back to back both wired in (with crimps) i
figure it has to be the ecu, its a black box 4-5" square, 1" deep, with 1
(or maybe2) bundles of wires coming out and a 4 or 5 way terminal block in
the middle, both boxes are dated 91, newer than the car, which leads me to
believe some one has performed this top end swap, and not swapped the bottom
end.
Any ideas on the dual ecu's?  My thoughts where that they could be
switchable somehow (chipped/unchipped).
Thanks.
