An alpha-N system only works well when the engine caracteristics are very well known. If you change anything, or if the engine wears a bit with age, the fueling becomes inaccurate.
This is about all I know. We eventually sold the Uno, after replacing the EFI with a conventional carburettor setup.
The Daewoo Cielo uses what I've been told is a standard (General Motors) Delco 808 ECU. (Note -- this is probably not true.) It uses a 32K eprom, and the code and tables are totally different from the ones used in cars produced by GM. The EPROM is in a blue carrier, labelled DELCO BWJT 0723
The Delco 808 uses a Motorola 68HC11 microcontroller. I couldn't find a decent disassembler on the web, so I wrote one, based on a 6809 disassembler I wrote yonks ago.
