Motronic error states / limp home mode

[Joseph Vella]

does anyone know a simple way to prevent the ecu from going into limp home
without re-programming the eproms, maybe from the diagnostic port ?

it is a '93 Audi S4 motronic, and I believe I'm getting the Manifold pressure sensor
failure mode ( due to it not agreeing with the air mass sensor, due to running
23 PSI of boost ) making it enter limp home after about 10 seconds on boost.

How long does the ECU take to recover from a power interruption (reset)
thought two was that I would reset the ECU at 5 second intervals when the boost 
exceeded 15 PSI ( say .02 sec pulse of the supply voltage ) ?

Thought 3 - which registers are responsible, I can cut a new EPROM if I have to,
but I'd rather not if it isn't necessary.

If someone has mapped one of these to 23PSI I wouldn't mind having the code ?

Thanks!
