My car is an '88 5kcstq, so yes, standard shift quattro.

However, the ecu came from Nate Stuart via Ebay, and it is a TAP-modified unit, so it may have come from an automatic.  It would certainly make sense if it is an auto ecu.

Is there a jumper wire on the ecu that I can check to see if it is cut or not?

I've heard of the CA car (vs. 49-state) jumper, but wasn't aware of the automatic jumper.  Or maybe I was confusing that for something I made up in my head!

Can I tell by the ecu model number or the like?

It is a very OEM-like "wall" it hits when this happens.  Like the 1.5+ bar cutoff, or the rev-limiter.

My car is also modified with a TAP WG spring and pressure regulator mod.  I plan to put the stock spring in the WG and crank up the regulator to bring it back up to the current max boost levels, which is about 14/15psi.  I have an APC queued for installation as well.  It's a big queue tho'.
