Bosch Motronic chipping

[quk at isham-research.freeserve.co.uk]

Got a problem with an S2 Avant - intermittent refusal to start.
Bosch Motronic - Audi 895 907 551B, Bosch 0 261 203 643/644.

Only code stored is 1111.

ECU has been chipped. Two chips - "SZF1551B Boost" and
"SZF1551BKey100 Fuel".  The Zs could be Ts.  The original
250kPa pressure sensor is still fitted.  Soldering is excellent.

Anyone any idea who did this, and whether this is one of the
mods that always stores 1111 straight from the factory?

Further - anyone know where I can get stock chips to restore the
car for diagnostic purposes?
