90 vert special issues with ecu and na engine

So I know I need a new ecu. The car is a 90 vert with a replacement na engine from an unknown 89 model.
That being said, I need to know which ecu model #'s will work in my s5. The top is already hard wired to the fuse box, so if the only difference in ecu's for the vert is top control, then that is non relevant. I just do not want to screw something else up. Thanks in advance!

Will those fit a coupe as well? I'm looking into a na coupe with similar issues.

Oh snap, I should have an S5 5 speed vert ECU laying around somewhere (blasphemous motor swap negated ECU need). Will try to find it tonight and get back to you.
