Just so everyone knows, all '06 Daewoo Delphi ECU's are probably going to be recalled for the cold weather problems. It's even worse with the Suzukis.

Latest TSB from Suzuki concerning Forenza's/Reno's:

06 Model year only

CONDITION: Engine will not start MIL “ON” and DTC P0606 (Control Module Performance)
stored. (This TSB does not apply to any vehicle with extended crank time-no
start only)
CAUSE: Outside temperature below -10º C (14º F) may cause an internal ECM circuit to
malfunction. This failure will prevent start up.
CORRECTION: Replace the Engine Control Module (ECM) with a new ECM as described below.

Please note the temp this condition may occur at.
TSB = Technical service bulletin
MIL= Malfunction Indicator Light, Check Engine Light, probably several other names
DTC = Diagnostic trouble code
