I don't think that is a valid error code. You can look on this website to verify HUD ECU Hacker (netcult.ch) I have this software along with the real Tetris adaptor and I can connect to the dephi ECU, read and reset error codes. I tried the cheap route as far as adaptors go but ended up buying the real thing. Here's the link to the delphi ECU manual. Microsoft Word - Delphi_CTC_Small_Engine_EMS_Service_Manual_Rev1_Eng.doc (netcult.ch) At the end of the manual are all the error codes and there isn't a 1111 listed.
